Soldering Sequence

  • Resistor 560 ohm (R20)
  • Green LED 3mm (D1)
  • Photo-interrupters (U1, U2). They are in opposite orientation.
  • 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.

Mounting post for Control Board

  • M3 x 10 screw + nut
  • brass post M3 x 25

    The hardware sucks, always breaks.Don't EIE have enough money to buy a good one?

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
