FriendlyELEC NanoPi M4 is a Rockchip RK3399 single board computer that follows Raspberry Pi 3 form factor, and was launched in a year ago for $65 with 2GB RAM, and $95 with 4GB RAM. Raspberry Pi 4 introduction brought some more competition, and helped the prices drop to $50 and $75 respectively.

But now the company has launched a revision 2 of the board, NanoPi M4V2 that replaces LPDDR3 memory with faster LPDDR4 memory, adds power & recovery buttons, and the audio jack now also support microphone input. It’s only available with 4GB LPDDR4 memory, and the price is lower at $70.

The rest of the specifications are mostly identical:

SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0GHz, 4x Cortex-A53 @ up to 1.5GHz, a Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC, and a VPU with 4K VP9 and 4K 10-bit H265/H264 6decoding

System Memory – Dual-channel 4GB LPDDR4

Storage – eMMC module socket ( now more reliable installation ), micro SD card slot

), micro SD card slot Video Output HDMI 2.0a up to 4K @ 60 Hz with HDCP 1.4/2.2 support 4-Lane MIPI-DSI connector

Audio – 3.5mm headphone jack with audio output and microphone input , HDMI digital audio output, microphone header

, HDMI digital audio output, Camera – One or two 4-lane MIPI-CSI connector(s) (one multiplexed with MIPI-DSI), dual ISP up to 13MP

Connectivity – Gigabit Ethernet, dual-band 802.11 a/b/g/n/ac WiFi, Bluetooth 4.1 with 2x u.FL antenna connectors

USB – 4x USB 3.0 ports, 1x USB 2.0 type-C port with OTG mode and power input

Expansion 40-pin GPIO header with 3x 3V/1.8V I2C, up to 1x 3V UART, 1x 3V SPI, 1x SPDIF_TX, up to 8x 3V GPIOs, 1x 1.8V 8-channel I2S 24-pin extension port with 2x USB 2.0 interface, PCIe x2, 1x PWM

Debugging – 4-pin UART header (3V 1.5Mbps)

Misc – Power key, power LED, user’s LED, 2-pin header for RTC battery, power & recovery buttons

Power Supply – 5V/3A via USB-C port; RK808-D PMIC

Dimensions – 85 mm x 56 mm (8-layer PCB)

Temperature Range – -20°C to 70°C

The company provides Android 8.1, Lubuntu 16.04 (32-bit), FriendlyCore 18.04 (64-bit), and FriendlyDesktop 18.04 (64-bit) firmware images, and basically everything is the same as for the original NanoPi M4 board, so software and accessories like NanoPi M4 metal case will be compatible.Alternatively you could also use Armbian.
