Assembly of F4Lite DB25 V1.1

Version 1.1 of this kit has much simpler – all you need to add are the connector, termination packs, and microcontroller module.

Back of the PCB, everything’s already there!

The above picture shows the back of the PCB. Capacitors, voltage regulator, fuse, and diode are already installed.

Please be sure to install the resistor packs correctly. This picture shows how they should be oriented:

Everything else is very straightforward. Put the USB port of the microcontroller module on the correct end!

See those empty part footprints on the bottom right? The fuse and diode are already installed, on the back of the board.
