Kimera core
What little available info that was available for the qmk port
- atmega32u4 16Mhz
- board seems to have a 6Mhz crystal
- 2x PCA9555 I2C IO expander

Bootloader
Default bootloader is atmel-dfu
.
Reboot to bootloader via magnetic switch next to icsp header.
Flash using regular dfu methods.
Southpaw Extended 65 pin mappings
Taken from kimera-config.json
"row_mapping": [ 2, 3, 4, 5, 6 ],
"col_mapping": [ 13, 14, 15, 16, 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 B5
Capslock
- PIN B6
Numlock
- PIN 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 | 2 | IC1 Port 0 pin 1 |
1 | 3 | IC1 Port 0 pin 2 |
2 | 4 | IC1 Port 0 pin 3 |
3 | 5 | IC1 Port 0 pin 4 |
4 | 6 | IC1 Port 0 pin 5 |
- Safe enough to assume
row_index == pin
COL index | Kimera Pin | PCA9555 |
---|---|---|
0 | 13 | IC1 Port 1 pin 4 |
1 | 14 | IC1 Port 1 pin 5 |
2 | 15 | IC1 Port 1 pin 6 |
3 | 16 | IC1 Port 1 pin 7 |
4 | 17 | IC2 Port 0 pin 0 |
5 | 18 | IC2 Port 0 pin 1 |
6 | 19 | IC2 Port 0 pin 2 |
7 | 20 | IC2 Port 0 pin 3 |
8 | 21 | IC2 Port 0 pin 4 |
9 | 22 | IC2 Port 0 pin 5 |
10 | 23 | IC2 Port 0 pin 6 |
11 | 24 | IC2 Port 0 pin 7 |
12 | 25 | IC2 Port 1 pin 0 |
13 | 26 | IC2 Port 1 pin 1 |
14 | 27 | IC2 Port 1 pin 2 |
15 | 28 | IC2 Port 1 pin 3 |
16 | 29 | IC2 Port 1 pin 4 |
17 | 30 | IC2 Port 1 pin 5 |
18 | 31 | IC2 Port 1 pin 6 |
- Need to read both ICs and corresponding port to compile the correct column data
- All pins are mapped sequentially
- maps to the usual practice of reading matrix columns
- Needs uint32_t to read 19 columns of data
Notes
- 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.
