Akruvia Maker Badge PCB:

Akruvia Maker Badge Dimensions:

Soldering steps:

Step 1: Solder male header pins to ESP32 TFT Feather

Step 2: SN74LV1T125

Step 3: 100nF capacitor

No polarity orientation

Step 4: RGB LEDs (RGB1-RGB5)

Step 5: Kailh Choc v1 hot swap sockets (SW4-SW8)

Step 6: female Header pins for ESP32 TFT Feather

Step 7: slide switches (SW1-SW2)

You could cut the legs of the slide switches if you want.

Step 8: encoder

Case assembly:

Step 1: Put the battery.

Step 2: Use the 2x 12mm M2.5 screws and 2x M2.5 lock nuts.

Step 3: Use the 4x 18mm M2.5 screws and 4x M2.5 lock nuts to attach the PCB to the case.
