Technical overview

• The system supports both a Raspberry Pi and an Arduino; jumpers select which board controls the peripherals.
• The motor drive uses an ST L298P dual H-bridge chip (up to 2 A per channel) with diode protection.
• Power comes from two series-connected 18650 batteries (nominal 7.4 V); the onboard LM2596 regulator provides stable 5 V to the boards.
• An onboard TLC1543 (10-bit, 11-channel) ADC allows the Raspberry Pi to read analog sensors.
• Modules include an infrared proximity sensor, ultrasonic ranging, line tracking, speed measurement using a coded disc and WYC-H206 photoelectric sensor, and a servo connector.
• Remote control options include an infrared receiver (NEC protocol), UART for a Bluetooth module, SPI for an NRF24L01 wireless module, and optional ZigBee.

Notes and version constraints

• The source does not provide explicit command-line commands; therefore no commands are listed.
• Depending on the purchased kit, some described modules or accessories may be missing; check the product page.
• Jumper settings are version-sensitive; if motors do not move, reposition the jumper cap as described in the user manual.
• If the green LED of the IR obstacle module stays on or off, adjust the module's potentiometer until the LED just turns off.
• Battery cells must not be discharged below about 3 V or 2.75 V per cell, otherwise permanent damage can occur.
• External power supplies must not exceed 12 V input voltage.
