QMK-based firmware for ASkeyboard Sono1 keyboard with additional Sono2 numpad
ASkeyboard Sono1 keyboard conversion project: direct connection of Black Pill to the matrix.
- Keyboard Maintainer: DmNosachev
- Hardware Supported: ASkeyboard Sono1, Black Pill STM32F103C8T6 MCU board. Alternatively you can use any MCU which is supported by QMK and has 28 IO pins or more (15x8 matrix and 5 LEDs): Teensy 2.0++, Blue Pill, etc.
Make example for this keyboard (after setting up your build environment):
make handwired/sono1:default
See the build environment setup and the make instructions for more information. Brand new to QMK? Start with our Complete Newbs Guide.
Modding
Matrix
ASkeyboard Sono1 has 15x8 matrix. Sono2 numpad connects directly to the main matrix.
Rows (R0-RE) and columns (R0-C7):
LEDs
Keyboard has 5 LEDs with common anode. Their cathodes are connected to R10–R14 resistors (you may want to replace them to adjust LED brightness for 3.3V voltage). Add 5 wire jumpers to connect them to the corresponding traces.
Black Pill
Suggested mount position for the Black Pill (view from the bottom side of the PCB):
R8 R9 RA RB RC RD RE L0 Vcc C7 C6 C5 C4 C3 C2 C1 C0 Vcc

Asterisk sign designates pins of the Black Pill that don't align properly with PCB and need to be rewired.
- Desolder all ICs, capacitors and resistors except R10–R14.
- Solder 4-pin SWD header to Black Pill.
- Burn STM32duino bootloader to Black Pill.
- Compile and flash the firmware:
make handwired/sono1:default:flash - Connect rows, columns and LED pads to the corresponding pins of the Black Pill.
Keymap
'CUR LOCK' key on Sono2 numpad has locking switch by default (Alps SKCL lock). QMK supports mechanical locking switches for CapsLock, NumLock and ScrollLock keycodes.
