More Details about Some Pin Connectors
1.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.
2.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.
3.I2C Communication Connector: GND / VCC(3.3V) / SCL / SDA are standard I2C connector. It is compatible with 3.3V I2C sensors and devices.
4.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.

Jargon buster
Plain-language definitions for the technical terms used above.
- CS
- CS stands for chip select, a control pin used by SPI devices to tell which connected device should listen. It matters when you connect more than one SPI module to the same microcontroller, because each device usually needs its own CS pin.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
