One powerful feature of the Tinker Board is the row of available GPIO (general purpose input/output) pins along the edge of the board. These pins are a physical interface between the Tinker Board and the outside world. At the simplest level, you can think of them as switches that can be turned on or off. Of the 40 pins, 28 are GPIO pins (shared with SPI/UART/I2C pins). The Tinker Board is equipped with one SPI bus that offers two chip selects. The SPI bus is available on the onboard 40-pin header.
