PolyU EIE3105 Hardware Info (a)

   Soldering Sequence 1. Resistor 100 ohm (R10, R11) 2. Hearder 4-pin right angle (UART1) 3. LED red x 8 pieces (D0 - D7) 4. LED green (B6) 5. Capacitor (C1, C2) 6. Socket 20-pin x 2 pieces (BD1) 7. Socket 4-pin x 2 pieces (J2, J8) 8. Header 4-pin straight (UART3) 9. Tactile switch (A12) 10. Socket, 4-pin x 2pc (J5, J6), 7-pin (J7)

   Component Order in Soldering 1) right angle header 2) 3-pin headers 3) 17-pin headers (fixture required) MCU Pinouts The on-board LED is connected to PB12. Pull it  LOW to turn it 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 powering up. Normally the jumpers should be set in NORMAL MAIN FLASH. Schematic
