Boardcon Idea3399 Feature-Rich SBC Comes with M.2 NVMe SSD and 4G LTE PCIe Sockets


A few years back, Boardcon introduced EM3399 single board computer powered by a Rockchip RK3399 processor through the company’s PICO3399 SO-DIMM system-on-module.

They’ve now designed another RK3399 based SBC , the Idea3399 – comprised of a baseboard and module, but instead of re-using the SO-DIMM module, CM3399 system-on-module with castellated holes was used instead. The new board comes with many of the same features as their first board but adds an M.2 NVMe SSD slot and mPCIe socket for 4G LTE modem on the back of the board.

CM3399 SoM

Key features and specifications:

  • SoC – Rockchip RK3399 dual Cortex-A72 @ 1.8GHz + quad Cortex-A53 @ 1.4GHz
  • System Memory – 4GB LPDDR4
  • Storage – 8GB eMMC flash
  • 202 castellated pin (1.3mm pitch) with  USB2.0 host, USB3.0 host, USB OTG, UART, MIPI, Ethernet, SPI, HDMI out, I2C, I2S, PCI Express, SDIO, SD/MMC, eDP, Camera, PWM, ADC IN, etc…
  • Power – Supply Voltage: 5V; RK808 PMU
  • Dimensions – 55  x 50mm (8 Layers, complying with EMS/EMI)

The module comes with Android 7.1.2 preinstalled and targets AIoT applications such as intelligent interactive devices, personal computers, and robots. The Android BSP is based on  Linux 4.4.126 and the cross-compilation toolchain runs on Ubuntu 16.04.

None of the software and related documentation is available publicly, but they do have some hardware documentation and datasheets which you’ll find on the product pages for the SoM and SBC respectively. Pricing has not been made public, but I understand the board and module have been available since late July.
