Photo Build Logs

Step 1: Flash and test the controllers

1. Connect the Sea Picro to the computer using a USB data cable.

2. Use tweezers to briefly connect the GND and RST pins for 2 seconds. Avoid shorting the 5V and GND pins to prevent controller damage.

3. Drag the .uf2 file of the DASBOB firmware onto the RPI-RP2 drive to flash the controller.

4. Open VIAL and check if the "DASBOB" keyboard is detected after flashing the controller.

5. If VIAL successfully recognizes the keyboard, then you are ready to proceed to the next step.

Step 2: Solder the components on the board

Here is the photo of the Right board of DASBOB

Front side of the Left board

Back side of the Left board (with the hotswap socket footprints)

To connect the controller, you will need to use the 12p and 5p pins. Insert these pins into the front side of the board, ensuring that the controller components are facing down towards the PCB.

Solder the pins (I normally solder the pins on the back side first)

Solder the other components (reset buttons, TRRS jacks and hotswap sockets) to the board

Last Step: Jumpers for Wired Builds

For wired builds, you'll need to close two solder bridge jumpers as shown below.

Done :)

After cleaning the board, you can insert the key switches to the hotswap sockets and connect the 2 halves of the board using the TRRS cable.

Important: Please fully connect the TRRS cable, then connect the USB data cable. Do not plug/unplug the TRRS cable when the keyboard is powered.
