+# orbweaver
+
+This firmware is for a Razer Orbweaver Chroma keypad, modded to replace the stock MCU
+with an Elite Pi RP2040 microcontroller. Mod instructions can be found on [geekhack](https://geekhack.org/index.php?topic=119396.0).
+
+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. I found that the I2C clock speed must
+be slowed down to 100 kHz for the IS31 chip to keep up (the default for RP2040 seems to
+be 400 kHz unless specified otherwise).  
+
+The default key map (layer 0) is a generic layer based on the original Razer defaults. 
+You can change or add layers as needed, and change static colors in keymap.c
+
+Many thanks to bomtarnes, Drashna, Dasky, sigprof, and casuanoob for helpful discussions
+and coding suggestions and snippets.
+
+* Keyboard Maintainer: [a_marmot](https://github.com/a-marmot)
+* Hardware Supported: RP2040 + IS31FL3731
+* Hardware Availability: [https://geekhack.org/index.php?topic=119396.0](https://geekhack.org/index.php?topic=119396.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/orbweaver:default
+
+Flashing example for this keyboard:
+
+    make handwired/orbweaver:default:flash
+    
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* Press and hold the upper left hand key on the main keyboard while you plug in the USB.
+* Press and release both reset buttons on the top of the RP2040 inside the modded unit.
