ISO Pad

This Guide will help you build your ISO macropad kit.

0 - What you need​

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

1 - Screw the standoffs in the case​

Use the flat head hex scres to mount the standoffs in the case

2 - Solder the headers on the PCB​

caution

Check the right side of the PCB before solder!

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.
