More Details about Some Pin Connectors
G / V(3.3V) / P3 / P4 / P6 are connectors for GVS electric bricks. Among it, P3 / P4 are connectors for analog / PWM / digital connectors, which can help you connect servos and various sensors conveniently.
UART Connector: V (3.3V) / G / TX / RX / S are serial port connectors. It is compatible with the common wireless communication modules like HC08 / HC11.
I2C Communication Connector: GND / VCC(3.3V) / SCL / SDA are standard I2C connector. It is compatible with 3.3V I2C sensors and devices.
SPI Communication Connector：V / G / CS / RS / AO / DA / CK correspond to the connector of TFT 1.8 inch LCD module. It can directly compatible with TFT 1.8 inch LCD module, including SPI communication connector on micro:bit board.
