+### Bootloader
+Default bootloader is `atmel-dfu`.
+Reboot to bootloader via magnetic switch next to icsp header.
+Flash using regular dfu methods.
+
+### XD84 pin mappings
+Taken from [kimera-config.json](https://github.com/kairyu/tkg/blob/master/keyboard/config/kimera-config.json)
+
+	"row_mapping": [ 1, 2, 3, 4, 5, 6 ],
+	"col_mapping": [ 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 ],
+
+# RGB
+- PIN C7
+- Number of RGB LED 7
+
+# Backlight
+- PIN B6
+
+# Light Through Cat
+    TODO - PWM C6
+
+## Assumptions
+### Pin/Port mappings
+- All cols are on the same IC
+- All rows are on the same IC and port
+- Pins mapped sequentially
+- Each port only does row or column not a mixture of both
+  - No need to have complex port config
+  - 
+
+| ROW index | Kimera Pin | PCA9555           |
+| ----------|------------|-------------------|
+| 0         | 1          | IC1 Port 0  pin 0 |
+| 1         | 2          | IC1 Port 0  pin 1 |
+| 2         | 3          | IC1 Port 0  pin 2 |
+| 3         | 4          | IC1 Port 0  pin 3 |
+| 4         | 5          | IC1 Port 0  pin 4 |
+| 5         | 6          | IC1 Port 0  pin 5 |
+
+- Safe enough to assume `row_index == pin`
+
+
+| COL index | Kimera Pin | PCA9555           |
+| ----------|------------|-------------------|
+| 0         | 17         | IC2 Port 0  pin 0 |
+| 1         | 18         | IC2 Port 0  pin 1 |
+| 2         | 19         | IC2 Port 0  pin 2 |
+| 3         | 20         | IC2 Port 0  pin 3 |
+| 4         | 21         | IC2 Port 0  pin 4 |
+| 5         | 22         | IC2 Port 0  pin 5 |
+| 6         | 23         | IC2 Port 0  pin 6 |
+| 7         | 24         | IC2 Port 0  pin 7 |
+| 8         | 25         | IC2 Port 1  pin 0 |
+| 9         | 26         | IC2 Port 1  pin 1 |
+| 10        | 27         | IC2 Port 1  pin 2 |
+| 11        | 28         | IC2 Port 1  pin 3 |
+| 12        | 29         | IC2 Port 1  pin 4 |
+| 13        | 30         | IC2 Port 1  pin 5 |
+| 14        | 31         | IC2 Port 1  pin 6 |
+
+- Safe enough to assume here col_index does not need to be converted to pin
+- Reading both ports one after the other gives us the same sequential behavior
+  - maps to the usual practice of reading matrix columns
+  - while this technically gives 16 column reads, the 16th column can never be set so is safely ignored
+
+## Notes
+[pca9555 datasheet](https://www.ti.com/lit/ds/symlink/pca9555.pdf)
+
+- Other Kimera based boards with non sequential pin mappings, pins mapped across ICs, or mixed row/col configs will need more complicated `pin -> i2c_addr,port,pin` logic as well as rather more complex pin functions.
+
+## Return to stock firmware
+Not tested but original firmware seems to be available in the [kairyu/tkg-firmware](https://github.com/kairyu/tkg-firmware/blob/master/kimera-core.hex) repo.
