Zerosprey42 MonoBlockSplit Unibody RP2040 Wired Keyboard Kit

Zerosprey42 Keyboard is a beginner friendly, choc hotswap, MonoBlockSplit (Unibody), column-staggered, DIY low-profile mechanical keyboard. It balances between portability and ergonomics with a sleek case. This is a remix of ebastler‘s osprey with a low cost RP2040-Zero.

Features

• MCU Board – WaveShare RP2040-Zero
  • It includes a powerful RP2040 with a lot of flash memory (2MB), so you can enable many QMK features and layers without worrying about the firmware size.
• Easier to solder (for the DIY soldering option)
  • There are very few components/pins to solder. You will need to solder diodes, hot swap sockets, and the castellated holes for the RP2040-Zero.
• Choc spacing
  • Key switches are arranged tighter than the standard spacing.
• Ergonomics
  • Slightly angled sides, with a bigger thumb key.
• Enclosure
  • There is an elegant case modified from the original osprey keyboard. It includes a top case, switch plate and a bottom case.
• Firmware
  • QMK and Vial are supported. For advanced users, you should be able to use other firmwares including ZMK, KMK (Python-based), PRK (Ruby-based), keyberon (Rust-based) and ZMK.

The Basic Kit includes

• 1x PCB
• 1x WaveShare RP2040-Zero
• 50x 1N4148 SOD123 diodes
• 42x Kailh hotswap choc v1 sockets

Notes

• You will need to solder the parts if you do not choose the presoldering option.
• DIY assembly by hand and a screwdriver is required for the case, key switches and keycaps.
• For 3D printed PLA parts, the default color is black. Please let me know in the order notes if you would like other colors or combinations.
• The switch plate is a soft, flexible plate. It is not a hard plate like FR4.
• This is a hardware DIY kit / product with minimum firmware support. For advanced firmware related features, please visit the community sites and Discord channels.
• You need to use a USB A-to-C or C-to-C data cable. Charging-only cable does not work.
