- Solder PICO micro controller to the top of the PCB facing up (components on top).
- Next solder the diodes of choice to the back of the PCB, these can be either surface mount or through-hole diodes
- Take note of diode direction.
- If using through-hole diodes you'll need to snip the excess from the legs on the other side.
- If you are installing LED's under the 18 switches then you can do this now.
- The LED's can be dropped into place from the rear of the board.
- Ensure that the notch on the GND pin lines up with the triangle marker on the PCB.
- These can be fiddly to solder and take a bit of patience but once the first leg is soldered then the others become easier.
- If you are opting to use a rotary encoder then this can be soldered next.
- This is positioned in the center and needs to be done before installing a top plate
- If you are using a top plate read on, otherwise skip to step 5 (To hold switches in place)
- Place each of your chosen switches into the top plate
- The pins should be on orintated with the pins north of the the stem if looking straight on.
- Place each of your chosen switches into the top plate
- Place the switches down onto the main PCB, ensuring all switches are flush to the board.
- Turn board over onto the reverse and begin soldering each of the switch pins to the PCB.
- If you've got a base plate cut then this is where you'll use M2 screws and M2 standoffs to join the top plate to the base.
- Installing Firmware/Flashing
- Using QMK from github, building firmware
- make ashwing66:default:flash or make ashwing66:via:flash (For VIA Support)
- Copying U2F straight to RP2040 storage
- Hold down the BOOT button on the Pico while connecting the USB, a new device should be detected as storage.
- Copy the Ashwing66_via.uf2 file onto the storage.
- Reconnect the keyboard once the USB storage disappears.
- Hold down the BOOT button on the Pico while connecting the USB, a new device should be detected as storage.
