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
Check the right side of the PCB before solder!
3 - Solder the microcontroller
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.
