The SparkFun HSTX PTH Breakout is a versatile board designed to interface with the HSTX connector on the RP2350 IoT RedBoard and the camera and display connectors on a Raspberry Pi 5. It facilitates prototyping by breaking out all 22 pins to a standard 0.1-inch spaced plated through-hole header. This includes four differential pairs, I2C signals, and power connections, enabling seamless integration with various peripherals such as cameras and displays.
