RK3399 SBC offers 40-pin and M.2 expansion

Oct 15, 2020 — by Eric Brown 3,175 views

The Novasom-M9 is a compact SBC that runs Android or Linux on the Rockchip RK3399 with GbE, HDMI, eDP, MIPI-DSI and -CSI, USB 3.0, 40-pin GPIO, and an M.2 slot.

Novasom Industries has launched a media-oriented, 105 x 56mm Novasom-M9 SBC equipped with the hexacore Rockchip RK3399. Novasom previously produced two SBCs based on Rockchip’s quad-core Cortex-A53 RK3328: the SBC-M7FT and the later, modestly enhanced Novasom M7+.

Three Novasom-M9 models are available:

  • SBC-M9D — 2GB RAM
  • SBC-M9E — 2GB RAM; 64GB eMMC
  • SBC-M9FT — 4GB RAM; 64GB eMMC

Otherwise, the boards are identical, running Android or Linux on the same RK3399 SoC with 2x Cortex-A72 cores 4x -A53 cores, and a high-end Mali-T860 GPU. No clock rates were listed but they are usually 1.8GHz or 2.0GHz for the -A72 and 1.4GHz for the -A53 cores.

Novasom’s spec presentation is a bit spotty in places. It appears that like the Novasom-M7, there is one USB 3.0 host port and micro-USB debug port on the coastline plus one more USB 3.0 and two USB 2.0 interfaces onboard. The board supplies coastline GbE and HDMI ports along with eDP, MIPI-DSI, dual MIPI-CSI, and 802.11ac with Bluetooth 4.1.

The Novasom-M9 is further equipped with a Raspberry Pi like 40-pin GPIO connector, an M.2 slot (type unknown), a microSD slot, an audio jack, and an RTC. The 12V SBC is available in 0 to 80°C and -20 to 85°C models. The board is referred to as a RASPMOOD design, which refers to 40-pin expansion, standardized connector types and positions, protected power input, and “USB extender.”
