What is Classic Peripherals?
3 parts
Classic Peripherals is an addon for CC: Tweaked. It adds a bunch of new peripherals and a couple of tweaks to existing ones, so it's aimed at you if you're building computers and automation with CC: Tweaked. This pack ships version 0.6.3.[1][2]
What it adds
- Radio Towers for long-range wireless communication. You build one from a Radio Tower Base, at least one Radio Tower Segment and a Radio Tower Antenna.[1]
- NFC and RFID. The NFC Reader can read and write data on an NFC Card, and it can write to an RFID Badge (write-only). The RFID Scanner reads all badges in its range wirelessly, with no user interaction.[1]
- A Cryptographic Accelerator with Ed25519 and X25519, AES encryption and SHA hashing, for securing your communications.[1]
- A Scanner peripheral that reads printed paper, including colors.[1]
Tweaks to know about
The mod nerfs the Ender Modem. In vanilla CC: Tweaked it can send and receive across all dimensions with virtually unlimited range. Per the project page, Classic Peripherals limits its range to 2x a normal wireless modem's range, unaffected by weather. Cross-dimensional messaging only works if the block position is close by, within 8 blocks, with scaling applied (1:8 for the Overworld and the Nether).[1]
It also adds the network name of the Redstone Relay peripheral to the redstone event, which is handy if you run several relays.[1]
Progression in this pack
Unverified The sources don't show any quests for this mod, any place for it on the ATM Star path, or any in-pack changes to its recipes or values. Treat the Ender Modem numbers above as the mod's own description, not a confirmed pack setting.
How do you get started with Classic Peripherals?
5 parts
Classic Peripherals is an addon for CC: Tweaked that adds extra peripherals and a few tweaks. You'll get the most out of it once you already have CC: Tweaked computers and modems, because several of the recipes build on those parts. This is the order I'd make things in.[1][3]
First, the Copper Coil
Start with the Copper Coil. It's the shared part for the NFC Reader, the RFID Scanner, the RFID Badge and the Radio Tower Antenna, so making a few early saves you trips later. The pack changed this recipe, so don't rely on what you remember from the mod's defaults.[3]

Next, NFC Reader and NFC Card
Next, the NFC Reader is a good first peripheral. It can read and write data on an NFC Card, and it can also write to an RFID Badge, though badges are write-only.[1]

Then, RFID Scanner and Badge
If you want something hands-free, make an RFID Scanner and some badges. The scanner reads all badges within its range wirelessly, with no player interaction. The badge recipe is changed by the pack.[1][3]

How does Classic Peripherals work?
6 parts
Classic Peripherals is an addon for CC: Tweaked, so everything here is a peripheral your computers talk to. You get a few tweaks to existing CC: Tweaked behaviour, a radio network, NFC and RFID, a cryptographic accelerator and a scanner for printed paper.[1]
Ender Modem tweak
In plain CC: Tweaked, Ender Modems reach everywhere across all dimensions. Classic Peripherals normally limits them to 2x the range of a normal Wireless Modem. Cross-dimensional messages then only work if the block position is close by, within 8 blocks.[1][4]
The two range settings are still in the config. enderModemRangeMultiplier is 2, a multiplier on the Ender Modem range where the base range is the same as the Wireless Modem. enderModemCrossDimensionalRange is 8. Both match the mod defaults.[5]
Redstone Relay event
The network name of the Redstone Relay peripheral is added to the redstone event. This is controlled by betterRedstoneRelayEvent, which is enabled in the pack.[1][5]
Radio towers
Radio towers help with long-range wireless communication. A tower is built from a Radio Tower Controller, at least one Radio Tower Pole and a Radio Tower Antenna, stacked together.[1][3]

Recipe id: classicperipherals:tower_head
The pack leaves the tower settings at the mod defaults. Height, counting the base and head, runs from radioTowerMinHeight = 2 up to radioTowerMaxHeight = 24.[5]
- radioTowerSegmentRange is the range per segment, set to 128.[5]
- radioTowerMinY is the minimum Y coordinate for maximum effective range, set to 96.[5]
- radioTowerLossFactor is the tower's loss factor, set to 0.15.[5]
- radioTowerMaxMessageSize is the maximum message size in bytes, set to 8,388,608.[5]
The config also has antennaCanBroadcast, which decides whether the Mini Antenna can broadcast instead of only receiving. It is true in the pack.[5]

NFC and RFID
The NFC Reader can read and write data on an NFC Card. It can also write to an RFID Badge, but badges are write-only for it.[1]
The RFID Scanner reads all badges within its range wirelessly, with no user interaction. In the pack, rfidScanRange is 8, and nfcMaxDataSize caps NFC card and RFID badge data at 128 bytes.[1][5]

Cryptographic Accelerator
The Cryptographic Accelerator gives your computers Ed25519 and X25519, AES encryption and SHA hashing. Its random bytes generator is capped by cryptographicRandomBytesMaxSize, which is 65,536 in the pack.[1][5]
The pack changed the main recipe. You can also convert between the full block and the Cryptographic Accelerator version with shapeless recipes.[3]

How do you progress through Classic Peripherals?
4 parts
Unverified The sources here do not show any quest in this pack that involves Classic Peripherals, and they do not place the mod on a quest path. The order below comes from the crafting recipes alone, not from a quest chapter.
Start with the Copper Coil
The Copper Coil is the building block for much of this mod. The pack changed its recipe, so don't rely on what you remember from the mod's defaults. Make a few first, because the RFID Scanner, NFC Reader, RFID Badge and Radio Tower Antenna recipes all take one.[3]

How does Classic Peripherals work with other mods?
3 parts
Classic Peripherals is an addon for CC: Tweaked, so every in-pack recipe that links it to another mod connects it to CC: Tweaked. All of these recipes belong to the radio network, which helps with long-range wireless communication.[1][3]
Radio tower crafting
To build a radio tower you craft a Radio Tower Controller, at least one Radio Tower Pole and a Radio Tower Antenna. Each of these recipes uses a CC: Tweaked item, such as the Networking Cable.[1][3]

Crafting Shaped
Recipe id: classicperipherals:tower_head
This is the mod's own recipe, and it needs the Ender Modem from CC: Tweaked.
The tower head is the part most tied to CC: Tweaked. Its recipe calls for the Ender Modem, which the pack names Ender Modem.[3]
Radio Antenna
The Radio Antenna is also built from CC: Tweaked parts, including the Wireless Modem. Its recipe is the mod's own and the pack does not change it.[3]

Ender Modem tweak
The mod's project page says Classic Peripherals nerfs CC: Tweaked's Ender Modem. In vanilla CC: Tweaked it can send and receive across all dimensions with virtually unlimited range. With this mod, its range is limited to 2x a normal wireless modem's range, unaffected by weather. Cross-dimensional messaging only works if the block position is within 8 blocks, with scaling applied (1:8 for the overworld and nether).[1]
Which Classic Peripherals config options matter?
3 parts
Most of Classic Peripherals' config is left at the mod defaults in this pack. There's one change that really matters, though, and it affects how you plan wireless setups. Everything lives in enderModemNerf and its neighbours in the same file.[5]
The one value the pack changed: Ender Modem nerf
enderModemNerf is set to false in this pack. The mod default is true. With the nerf on, the mod limits Ender Modems to 2x the range of a normal wireless modem and only allows cross-dimensional messaging when the block position is within 8 blocks (scaled 1:8 for the Overworld and Nether). Since the pack turns the nerf off, you shouldn't plan around those limits.[1][5]
The pack leaves enderModemRangeMultiplier at 2 and enderModemCrossDimensionalRange at 8, both the mod defaults.[5]
Unverified Whether those two range options still have any effect while the nerf is disabled is not confirmed by the available sources.
Radio tower settings (all mod defaults)
If you build Radio Towers for long-range communication, these are the values to know. The pack hasn't changed any of them.[1][5]
- radioTowerMinHeight is 2 and radioTowerMaxHeight is 24. Both heights include the base and the head.[5]
- radioTowerMinY is 96. This is the minimum Y coordinate of the tower for maximum effective range.[5]
- radioTowerSegmentRange is 128. This is the range per segment.[5]
- radioTowerLossFactor is 0.15.[5]
- radioTowerMaxMessageSize is 8,388,608 bytes.[5]
Other options at their defaults
- rfidScanRange is 8. This is the maximum range of the RFID scanner.[5]
- nfcMaxDataSize is 128 bytes. This is the data limit for NFC cards and RFID badges.[5]
- cryptographicRandomBytesMaxSize is 65,536. This is the most bytes the cryptographic accelerator's random bytes generator will produce.[5]
- antennaCanBroadcast is true, so the Mini Antenna can broadcast and not just receive.[5]
- betterRedstoneRelayEvent is true. The Redstone Relay's network name is added to the redstone event.[1][5]
What changed in Classic Peripherals between versions?
2 parts
FTB StoneBlock 4 1.21.0 ships Classic Peripherals 0.6.3. The mod has been in the pack since 1.19.0 or earlier, so it's not a new addition.[2]
Mod 0.6.3
- Turtles with upgrades now show up in the creative tab.[6]
- Pocket Computers with upgrades are in the creative tab too.[6]
- Colored NFC Cards and colored RFID Badges were added to the creative tab.[6]
- A new configuration option, cryptographicRandomBytesMaxSize, limits the size of cryptographic_accelerator.randomBytes(). If you write scripts that ask the cryptographic accelerator for random bytes, this is the cap to know about.[6]
Mod 0.5.1
- Bugfix: Radio Towers emit particles for every message, as the changelog words it.[7]
Unverified No pack changelog entries for Classic Peripherals were available, so any changes the pack itself made to this mod are unverified. The notes above come from the mod's own changelogs.
