Professional GPIO expansion board with 8 RJ45 40-pin ports for Raspberry Pi 1A+ 1B+ 2B 3B 3B+ 3A+ 4B

Discover our Raspberry Pi expansion board, designed to simplify and extend the capabilities of your projects. This breakout board offers high compatibility with 40-pin Raspberry Pi models, including the 1A+, 1B+, 2B, 3B, 3B+, 3A+, and 4B versions, thus meeting the diverse needs of users. It is equipped with eight RJ45 connectors that allow for convenient and secure connections between the GPIO pins and the power supply of your Raspberry Pi and peripherals, providing comprehensive expansion capabilities. Each RJ45 port benefits from flexible power supply, supporting independent selection between 5V, 3.3V, or power via the blue terminal block, to precisely meet the power requirements of your external devices. The GPIO pinout is optimized: each of the eight ports supports different interfaces such as UART, SPI, GPIO, and I2C, facilitating interaction with a wide range of peripherals. The pinout details per port are as follows: Port 1 (UART: RXD, TXD, GPIO17, GPIO4), Port 2 (SPI: SCLK, CE0, MISO, MOSI), Port 3 (GPIO6, GPIO12, GPIO5, CE1), Port 4 (GPIO21, GPIO26, GPIO20, GPIO19), Ports 5 to 8 (I2C: SDA, SCL with various GPIO combinations). Additionally, the board features a 2x20-pin expansion design, allowing you to easily add more peripherals to your Raspberry Pi for even more innovative and practical projects. This breakout board is made of high-quality PCB material. You will receive exactly one Raspberry Pi expansion board.
