Milk 2%

This Guide will help you build your Milk2% macropad kit.

0 - What you need​

  • Solder Iron
  • Solder wire
  • Soldering skills
  • A computer in order to flash the firmware (MacOS, Windows, Linux)

1 - Solder pin headers to the pcb​

caution

Make sure to solder the ehaders in the right side of the PCB as shown.

2 - Insert switches and solder switch pins​

Insert the switches in the macropad, carefully in the right orientation as shown, position the PCB in the Milk case in the right side with headers facing up and with the label This side up and towards port facing the USB hole of the case.

3 - Solder the microcontroller​

caution

Make sure of which microcontroller you are using, this tutorial shows a Promicro32u4 and Helios RP2040, follow the right part!

3.1 ProMicro ATMel32u4​

Position the microcontroller facing up (with the chip showing up), solder the needed pins.

3.2 Helios RP2040​

Position the microcontroller facing up (with the chip showing up), check the photo for the pin position as the Helios has an extra row of pins.

4 - Flash the firmware on your microcontroller​

Like step 3, this one too has 2 different paths depending on the microcontroller you have.

4.1 - ATMel32u4​

Flash your firmware with QMK blablablabla... link firmware

4.2 - RP2040​

Connect the RP2040 to your computer, it should show up as a RaspberryPi memory drive.

Copy ZanniKB's ARM Firmware available from HERE in the root memory off the RP2040.

Your microcontroller will automatically reboot after the file has finished transferring.

5 - Configure your macropad​

Using VIA you can now set custom macros or keys to your macropad.
