Sick macropad Estella! Your PCB wiring is a bit off though, you need to wire GND and 3V3 on your XIAO, if you need any help with it, feel free to send a message in #blueprint on slack! You also need to change the PCB a bit to qualify for a grant, this means adding a rotary encoder, maybe an OLED, some more keys and neopixels, it's up to you, it just needs to be moderately different from the tutorial!
