EIE3105 / EIE3106 Robot Car Info

  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

  The primary use of this USB to TTL module is uploading program to the robot car. Secondly, it helps communication between robot car and a personal computer via the UART interface. The wifi modules can also be connected to PC through this device. Uploading program When connecting to UART of robot car, use the 3.3 volts line. Connecting to UART 2   Connecting to UART 3 Connecting to HC-05 / HC-06 The input voltage of the WiFi modules is 5 volts.
