*The NanoPi M4 is a RK3399 SoC based ARM board. It has the same form of factor as the RPi B3+ and has ports and interfaces compatible with RPi B3+ too. On a 85 x 56 mm compact board there are rich hardware resources. These features make it a good platform for rapid product prototyping and various applications.
*The NanoPi M4 has an onboard 2.4G & 5G dual-band WiFi + Bluetooth 4.1 combo wireless module, four USB3.0 Type A host ports, one Gbps Ethernet port, one HDMI 2.0 Type A port, one 3.5mm audio jack and one Type-C port. In addition it has a RPi compatible 40-pin connector, dual MIPI-CSI camera interface, PCIe x2, USB2.0 x2, eMMC socket, RTC port and etc.
*The NanoPi M4 has two RAM options: 4GB LPDDR3 and 2GB DDR3.  Both can be booted from either a TF card or an external eMMC module.
*The NanoPi M4 supports Ubuntu Desktop 18.04(64-bit), Lubuntu 16.04(32-bit), Ubuntu Core 18.04(64-bit), Android 7.1 and Lubuntu Desktop with GPU and VPU acceleration. With these rich resources and powerful performance it can be widely used in applications of machine learning, AI, deep learning, robots, industrial control, industrial cameras, advertisement machines, game machines, blockchain and etc.
