As expected, FriendlyELEC has now launched NanoPi M4 board, a lower cost version of NanoPC-T4 Rockchip RK3399 SBC, and mostly following Raspberry Pi form factor.
NanoPi M4 board specifications:

FriendlyELEC provides Android 7.1, Lubuntu Desktop, Ubuntu Desktop 18.04 64-bit, Lubuntu 16.04 32-bit, and Ubuntu Core 18.04 64-bit image for the board, as well as fairly good documentation – as usual – on the Wiki.
If you want to get an idea of the stability and performance of the Android 7.1 firmware reading NanoPC-T4 Android review would be a good indication, and as we’ve just seen in Firefly-RK3399 review, cooling is really important to get the most out of Rockchip RK3399 board.
That’s why beside the board you should definitely add the $6.99 heatsink which cover the full area of the board (see above). Other accessories which you can tick during your order include a USB Type-C to USB-A male 2.0 cable (useful for firmware updates), an 8GB eMMC Module ($9.90) for better performance, a micro SD to eMMC adapter to flash firmware to the eMMC module, a 2.0MP USB camera module, a 13.2MP MIPI camera module ($25.00), a USB 1602 LCD Module, and/or for some hard-to- understand reasons, a mini USB WiFi dongle.
