BPI-R1 GPIO Pin define

GPIO define

We can check R1 PIN definition in this thread, including CON1, CON2, CON3, J12 and J13.

J13 contains the default serial port UART0 (UART0-RX,UART0-TX). UATR0 is configured to be used for console input/output. Whilst this is useful if you want to login using the serial port. So it is the most common used PIN.

J12 also contains serial port. CON3 contains CAN bus, SPI bus, PWM, serial port and etc. It can be configured to be used for kinds of peripherals.

CON1 is a CSI camera connector.

CON2 is a DSI display connector.

Pictures and tables below show the specific layout and definition of PIN.

CSI Camera Connector Pin specification:

the CSI Camera Connector is a 40-pin FPC connector which can connect external camera module with proper signal pin mappings. The pin definitions of the CSI interface are shown as below.
