U.con assembling guide

  • Only bootloader was installed. After soldering, you have to upload firmware.
  • When you order more than 2 pieces, sometimes PCBs are chained in a row. If then, you should separate them.

  1. Soldering

    1) Main board

– Resistors have no direction(polarity)

– Capacitor 2(C2) has direction. Solder it like the pic.

– Crystal shoud be added like the pic.

– Diodes and Transistors should be soldered like the pic. They look similar so don’t be confused.(You can tell them by the lable on them)

 

– MCU(IC1) also has direction.

 

2) USB Board for Connector

4) Like the pic below, connect USB after shorting FW_JP(col1, row2). Bootloader starts.

If you are shorting KEY_JP(col2, row2), then BootMapper starts.
