Rockchip RK1808 neural network processing unit was initially an IP Block inside RK3399Pro, but the company eventually launched RK1808 Cortex-A35 processor as a standalone solution now providing up to 3.0 TOPS for AI inferencing in modules, USB sticks, and development kits.
Boardcon offers another option with EM1808, a Rockchip RK1808 SBC equipped with the processor. The board should be suitable for two main types of AI applications, namely smart audio applications thanks to four audio ports, speaker header, & an onboard 4-mic array, and computer vision with MIPI CSI & DSI interfaces.
Boardcon EM1808 board is comprised of a baseboard and CPU module with the following overall specifications:
- SoC – Rockchip RK1808 dual Cortex-A35 processor up to 1.6GHz with 3.0 TOPS (for INT8) NPU, VPU supporting H.264 1080p60 decode, 1080p30 encode
- System Memory- 2GB LPDDR3
- Storage – 8GB eMMC flash, MicroSD slot, M.2 NVMe SSD interface
- Display I/F – 26-pin MIPI DSI header
- Camera I/F – 26-pin MIPI CSI header
- Audio – 3.5mm audio jack, three 3.5mm I2S jacks for DAC output, 4-mic array, speaker header
- Networking & Wireless Connectivity
- Gigabit Ethernet port (RJ45) via Realtek RTL8211E
- 2.4 GHz 802.11b/g/n WiFi 4 + Bluetooth 4.0
- Optional 4G module via mini M.2 socket + Nano SIM card slot
- Optional GPS module (Ublox 7)
- USB – 3x USB2.0 Host port, 1x USB3.0 Host
- Expansion – 12-pin GPIO header with I2S, UART, ADC, and PWM; 2-pin CAN bus terminal block, 3-pin RS485 terminal block
- Debugging – 3-pin UART header for serial console
- Misc – RTC + CR1220 backup battery; buzzer; reset, recovery and power buttons; USB 3.0 / M.2 PCIe switch (only one available at the same time)
- Power Supply – DC 5V/3A
- Dimensions – Baseboard: 131 x 91mm; castellated module: 55x 35 mm
It should be noted USB 3.0 and PCIe are multiplexed and that’s why there’s a switch so it’s only possible to use the USB 3.0 port when the M.2 connector is not used for 3G/4G cellular modem or NVMe SSD.
The company will provide a Linux BSP based on U-boot 2017-09 and kernel 4.4.185, and the Rockchip SDK for RK1808 supports TensorFlow and Caffe frameworks, ONNX and Darknet models.
Boardcon usually sells its modules and boards online, but there’s still no price for EM1808 SBC and the unnamed module it relies upon. Check out the product page for further information
