Orange Pi Prime Single Board Computer {#_orange_pi_prime}
=============================
Orange Pi Prime is a Allwinner H5 based SBC(Single Board Computer) by Orange Pi. It can run android or some Linux distributions. Orange Pi Prime features a quad core ARM processor, 2GB DDR3, HDMI, CSI, 3.5mm jack with CVBS video out, onboard mic, 802.11 b/g/n WIFI, Bluetooth 4.0, USB Port, Ethernet, 40-pin expansion header. Also, Orange Pi Prime supports USB OTG and has barrel jack for power.
Board Support
-------------
- [Orange Pi Prime](http://www.orangepi.org/orangepiwiki/index.php/Orange_Pi_Prime)
Interface notes
---------------
- On Armbian, use armbian-config to enable UART, I2C, PWM and SPI on expansion header.
Pin Mapping
-----------
Orange Pi Prime has a 40-pin expansion header.
