Radxa Rock has two 2.54mm 40 pins(20*2) extension header on board, which includes GPIO, I2C, SPI, Line in, USB 2.0, PWM, ADC, LCD etc interfaces. You can easily connect the breadboard or other sensor board to the rock. All the rock/rock pro/rock lite is compatible on the extension header, so it works on any hardware revision.
