Arbor Technology has introduced a pair of System-on-Module (SOM) products both based on Rockchip SoCs, the RK3399-based SOM-RK391 and the Rockchip PX30-based SOM-RP301. Both modules run Ubuntu, Buildroot, or Android 9.0. Along with the pair of modules, the company has also released the PBA-9000-A, its SOM-Series, single pin-out design carrier board.
The Rockchip RK3399 SoC has been a favorite among high-end community backed Arm-based boards over the last couple years, and we’ve covered at least one every month over that period. Recent examples include Arbor’s own EmQ-RK390 Qsevenmodule, Geniatech’s DB9 SBC and Vamr’s 96Boards CE-compatible Rock960 Model C. In contrast, the SOM-RP301 appears to be the first module we’ve seen based on Rockchip’s low-power PX30 SoC.
Built around the Rockchip RK3399 hexa-core (2x Cortex-A72 + 4x Cortex-A53) SoC, the SOM-RK391 is designed for high-performance applications such as AI computing, edge computing and machine vision, according to Arbor.
The RK391 also provides WiFi /Bluetooth support including 2T2R 802.11 a/b/g/n/ac for WiFi and Bluetooth 5.0 with real simultaneous dual-band (RSDB). You also get 2x MIPI CSI RX camera interfaces with 13MP ISP. For I/O you get 4x USB 2.0, 2x USB 3.0 2 (Type C), 2x 2-wire UART ports and 2x 4-wire UART ports. There’s also support for RTC, 10-bit 1MS/s ADC, SDIO, DIO, GPIO, SPI and I2C.
The SOM-RP301 meanwhile is based on the Rockchip PX30 Quad-Core Cortex-A35 processor and measures a compact 70 x 50 mm. Arbor touts the board for its low power consumption, flexible thermal management, cost-efficiency and its suitability for IIoT applications. The combination of its hardware media decoder and processing power makes it a fit to implement in retail kiosks such as electronic restaurant menus, automated currency exchange machines, ticketing kiosks and so on, according to Arbor.
The RK391 also provides WiFi /Bluetooth support including 1x 802.11 a/b/g/n/ac for WiFi and Bluetooth 4.0. You also get 1x MIPI CSI RX camera interface with 8MP ISP. For I/O the RP301 provides the all the same ports as the RK391 as described above. Despite the fact that Arbor touts the RP301 as a low power solution, its datasheet currently says “TBD” for the board’s power consumption.
PBA-9000-A SOM Carrier Board
Arbor’s PBA-9000-A Carrier Board for its SOM-series features a single pin-out design that enables it to easily support future boards in the Arbor SOM-series CPU Board family. The PBA-9000-A’s I/O configuration supports all of the interfaces on the SOM-series boards.
