DaESK - Dual axis Ergonomic Split Keyboard

DaESK is designed as an Ortholinear split keyboard with a detached thumb-key cluster, allowing a different angle/level of tent and positioning for the two parts.

Key design features:

• Full SMD design with onboard Atmega32u4 MCU compatible with QMK/TMK and other firmware suites.
• Onboard IS31FL3737 RGB controller for full per-key adressable RGB matrix with built in effects.
• Cherry MX type keyswitches in Kaihl Hot-Swap sockets.
• Mid-mounted USB-C connector for durability and low profile.
• Dual sided reversible design, identical PCB and thumbcluster PCB for both halves.
• Each half can work as a master/slave pair (TRRS/I2C link) and as a one-hand gamepad without reprogramming.
• Flexible thumbcluster design, supports 1-8 keys per side, connected to main PCB with ribbon cable.

Available main layouts:

• DaESK-4R a ~60%, 4-Row (4x6 key) layout with 48 keys plus 2-16 key thumbcluster for a total of 50-64 keys.
• DaESK-3R a ~40%, 3-Row (3x6 key) layout with 36 keys plus 2-16 key thumbcluster for a total of 38-52 keys.

Available Thumbcluster layouts:

• DaESK-TH1 an adaptable ErgoDox style thumbcluster with break-away parts.

Planned features:

• Already designed in mounting holes for a low profile FR4 midplate/backplate case design.
• Multiple thumbcluster designs.

Current Version: v0.9x - Almost ready for prototype PCB order
