SIG9 Macropad

Informazioni su questo modello

SIG9 A 3x3 handwired macropad for a Raspberry Pi Pico or a Pico-shaped RP2040 clone. The keys and the LED strip are configured in VIA. V2 is now slimmer, uses this Pico Clone: https://a.co/d/0gPIyDTJ , and is USB C. No more heatset inserts, just four M3*16mm screws. What you need A Pico or a Pico clone with a BOOTSEL button Nine switches, each with a diode, wired as a matrix A WS2812 strip of 11 LEDs QMK installed, including the ARM toolchain (qmk setup) A Chromium browser (Chrome, Chromium, Brave, or Edge). Firefox cannot talk to VIA. Wiring Rows, top to bottom: Top row: GP2, header pin 4 Middle row: GP3, header pin 5 Bottom row: GP4, header pin 6 Columns, left to right: Left column: GP7, header pin 10 Middle column: GP6, header pin 9 Right column: GP5, header pin 7 Each diode points from the column to the row. The banded end goes to the row wire. The other end goes to the switch, and the switch goes to the column wire. LEDs: Data in: GP28, header pin 34, through a 330 to 470 ohm resistor at the Pico 5V: VBUS, header pin 40 Ground: any GND pin Brightness is capped at 128 so 11 LEDs stay within what a USB port can supply. The red LED next to the USB plug is a power light wired to the board. Firmware cannot turn it off. Build and flash Extract the .zip at keyboards/handwired/sig9 inside your QMK checkout. From that checkout, run: qmk compile -kb handwired/sig9 -km default Hold BOOTSEL and plug the board in. A drive named RPI-RP2 appears. Then run: qmk flash -kb handwired/sig9 -km default After the first successful flash, double-tap the RESET / RUN button to enter the bootloader again. Holding the top-left key while plugging in also enters the bootloader, and it clears the layout saved by VIA. VIA This keyboard is not in VIA's public list. The layout file is via.json in this folder. Open usevia.app in a Chromium browser. Open Settings and turn on Show Design Tab. Leave Use V2 definitions turned off. On the Design tab, click Load and choose via.json. The Configure tab then shows the 3x3 and a Lighting section. The keys start as 1 through 9. Changes you make in VIA are stored on the keyboard. Editing keymap.c and flashing again does not replace them until you clear the saved layout by holding the top-left key while plugging the board in. If you load via.json again later, delete the existing SIG9 entry under Draft Definitions first. VIA keeps the old copy when the vendor ID matches. V1 uses four M3*8mm Heat Set Inserts and M3*25mm Screws to close it up.
