Component Order in Soldering 1) right angle header 2) 3-pin headers 3) 17-pin headers (fixture required) Pinouts The on-board LED is connected to PB12. Pull it LOW to turn on . It can be programmed either through the 4-pin header or through UART1. To program through UART1, set the jumpers to SERIAL PROGRAMMING before power up. Normally the jumpers should be set in NORMAL MAIN FLASH. Schematic

Capacitors (C6, C10,C11,C12) Sockets 4-pin (J5, J6), Socket 7-pin (J7) Terminal blocks (J3, J4). Beware of the orientation. Battery holder. Check orientation Switch  Other modules Ball caster Infra-red light panel (use M3 x 8 screws) Gear-box (38.2:1). Use two drilled gears in place of photo-interrupters (U1, U2).  Wires connecting motor to PCB AWG#20 40mm in length for the end connecting to motor: stripped 2mm and tinned for the end connecting to terminal block: stripped 5mm, do not tin. solder wire to tab of motor. There is no need to push wire into eyelet of the tab.   Wheel The construction of the wheels are different to the illustration provided by vendor. Please refer to the sample given.
