Prepare the Mainboard

If the mainboard does not have any firmware, you need to install it for the first use

Info

If you have bought the hardware kit, the mainboard already has firmware installed, but it’s a good idea to update it to the latest version anyway.

If you have just soldered the mainboard yourself, you will need to upload firmware once via USB. This is because without the firmware, the main Raspberry Pi won’t turn on.

For this, follow the Manual Firmware Installation guide.
