Orange Pi Prime Single Board Computer {#_orange_pi_prime}
2+
=============================
3+
4+
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.
