Firefly-RK3399 is a development board powered by Rockchip RK3399, and the company behind the board has now launched a system-on-module called RK3399 Coreboard with 2 to 4GB RAM, 8 to 128GB flash, a PMIC, and a 314-pin MXM 3.0 edge connector exposing various I/Os.
- SoC – Rockchip RK3399 hexa-core big.LITTLE processor with dual core ARM Cortex A72 up to 2.0 GHz and quad core Cortex A53 processor, ARM Mali-T860 MP4 GPU with OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL and DX 11 support
- System Memory – 2GB or 4GB DDR3
- Storage – 8, 16, 32 or 128 GB eMMC flash
- Carrier Board Interface – 314-pin MXM 3.0 edge connector with Ethernet, PCIe, HDMI 2.0, DP 1.2, MIPI DSI, eDP 1.3, S/PDIF, I2S, GPIO, USB, etc… signals
- Power Supply – 5V/3A input; RK808 PMIC
- Dimensions – 82 x 63 mm
- Weight – 24 grams
The company provides support for Android 6.0.1 and Ubuntu 16.04 for the module, and we should expect the same kind of support as for Firefly-RK3399 board. In order to help their customers getting started before they design their own custom board for the module, T-Firefly also offers a complete development kit combining RK3399 Coreboard with a carrier board.
The carrier board – which they call backplane – exposes the following interfaces and I/Os:
- Video Output – HDMI 2.0, MIPI DSI, DVP interface, eDP 1.3
- Camera – MIPI CSI
- Audio – Audio in/out, built-in microphone, speaker header, optical S/PDIF, MIC IN header, LINE OUT header
- Storage – 2.5″drive SATA connector (back of the board), PCIe M.2 M key, micro SD card slot
- Connectivity – Gigabit Ethernet (RJ45), Fast Ethernet (RJ45), WiFi and Bluetooth module, mini PCIe slot for LTE module + SIM card slot
- USB – 2x USB 2.0 host ports, 1x USB 3.0 port, 1x USB type C port, micro USB port
- Expansion – 30-pin GPIO header
- Misc – IR receiver, power/recovery/reset keys, RTC battery header, fan connector
- Power Supply – Via power barrel jack
- Dimensions – TBD
Either they’ve hidden it well, or they don’t have product page for RK3399 Coreboard on their website, and the only place where we’ll find some information is RK3399 Coreboard page in their online shop with the SoM going for $95 with 2GB RAM, 8GB flash, and $119 with 4GB RAM, 16GB flash, The development kit and variant of the SoM are not sold online (anymore), so you’d have to contact them to find about pricing and availability.
