# rp2040_orbweaver
|
||
|
|
QMK firmware for RP2040 based MCU replacement PCB for the Razer Orbweaver gaming keypad
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
This firmware is for the Razer Orbweaver Chroma keypad with a custom, plug and play, RP2040 MCU PCB. For installation instructions and board availability see [geekhack](https://geekhack.org/index.php?topic=124092.0).
|
||
|
|
|
||
|
|
The firmware controls a 6x5 key matrix (4x5 keypad + 6 additional keys on the thumb pad and up to 4 additional keys added by user). It also controls a IS31FL3731 RGB Matrix controller (on the Chroma model) via I2C interface. This requires a single I2C Driver with 20 common anode RGB LEDs.
|
||
|
|
|
||
|
|
Key 20 (bottom right) is used to switch layers.
|
||
|
|
|
||
|
|
The default key map provides 3 preset layers.
|
||
|
|
|
||
|
|
(layer 0) is a generic layer based on the original Razer defaults.
|
||
|
|
(layer 1) replaces modifier keys with letter keys.
|
||
|
|
(layer 2) replaces the 2 top rows with RGB control keys.
|
||
|
|
|
||
|
|
The three LEDs on the thumb pad indicate the active layer.
|
||
|
|
|
||
|
|
Blue = layer 0
|
||
|
|
Green = layer 1
|
||
|
|
Yellow = layer 3
|
||
|
|
|
||
|
|
All LEDs will be off when any other (user added) layout is activated
|
||
|
|
|
||
|
|
A set of RGB animations are included in confg.h. These are controlled by activating the Yellow layer and using keys 01 - 11 (11 toggles the lighting on and off - see /keymaps/default/keymap.c for more information)

Many thanks to a_marmot. Without his original handwired project, this board would not have been possible. His original work can be found here. [geekhack](https://geekhack.org/index.php?topic=119396.0).
