QMK-based firmware for ASkeyboard Sono1 keyboard with additional Sono2 numpad

Sono1

ASkeyboard Sono1 keyboard conversion project: direct connection of Black Pill to the matrix.

  • Keyboard Maintainer: DmNosachev
  • Hardware Supported: ASkeyboard Sono1, Teensy 2.0++ or 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): Blue Pill, Black Pill STM32F4xx, etc.

Make example for this keyboard (after setting up your build environment):

qmk compile -kb 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): Sono1 rows and columns

Desolder all ICs, capacitors and resistors except R10–R14.

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.

Sono1 LEDs

Teensy 2.0++

Asterisk sign designates pins of the Teensy that don't align properly with PCB and need to be rewired.

  1. Compile and flash the firmware: qmk compile -kb handwired/sono1/t2pp:default:flash. Press the reset button on Teensy to launch the bootloader.
  2. You will need to solder several pin headers to Teensy: two 7 pin headers (C0–C7, D5–B7), 8 pin (F0–F7) and 4 pin (B1—B4).
  3. Solder the Teensy to keyboard's PCB. You will need to manually reroute only 3 pins.

Asterisk sign designates pins of the Black Pill that don't align properly with PCB and need to be rewired.

Black Pill

  1. Solder 4-pin SWD header to Black Pill.
  2. Burn STM32duino bootloader to Black Pill.
  3. Compile and flash the firmware: qmk compile -kb handwired/sono1/stm32f103:default:flash
  4. 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.

There is 'debug' keymap which doesn't output any scancodes, but displays row and column numbers of pressed buttons to console (hid_listen or QMK Toolbox).
