SigmaStar SSD201/SSD202 are low-cost, highly integrated SoC’s with a dual Cortex-A7 processor, 64MB to 128MB on-chip RAM designed for Full HD smart displays, but we’ve also found SSD201 in a 4G LTE industrial gateway.
There’s now a different type of board based on the SigmaStar processors with Wireless Tag/Industio IDO-SBC2D06-V1B-12W and IDO-SBC2D06-V1B-22W SBC’s powered respectively by SSD201 and SSD202, and both equipped with dual Ethernet and a connector for a 4-inch or 7-inch display.
- System-on-Module (one or the other)
- IDO-SBC2D06-V1B-12W SBC – IDO-SOM2D01 module with SigmaStar SSD201 dual-core Cortex-A7 processor @ 1.2 GHz with 2D GPU, 64MB DDR2, 2Gbit SPI NAND flash
- IDO-SBC2D06-V1B-22W SBC – IDO-SOM2D01 module with SigmaStar SSD202 dual-core Cortex-A7 processor @ 1.2 GHz with 2D GPU, 128MB DDR3, 2Gbit SPI NAND flash
- Storage – MicroSD card slot
- Display – 4-lane MIPI DSI connector for 4-inch RGB565 display or 7-inch RGB888 display
- Audio – 2-pin Microphone connector
- Dual 10/100M Ethernet ports
- Sigmastart SSW101B 802.11b/g/n 2.4GHz 1T1R WiFi 4 module + u.FL antenna connector
- USB – 1x USB port, 1x Micro USB port
- 40-pin expansion header with GPIO, UART, DMIC, USB, etc… as well as 5V, 3.3V and GND power signals
- 6-pin UART header
- Debugging – 4-pin UART console connector
- Power Supply – TBD (5V via Micro USB port?)
- Dimensions – Around 86 x 55 mm
Wireless Tag did not reply to our email asking for additional information in time for the publication of this article, so all details come from the text and photos from Taobao, where the boards are sold for 170 and 180 RMB ($26 and $27.6 US) respectively.
The SBC should run Linux with an SDK from the company, but as noted in previous SigmaStar SSD20x product news, Daniel Palmer (and maybe others?) is/are working on mainline Linux, and the aforementioned industrial gateway could boot with mainline Linux last January. The SSW101B WiFi module code can also be found on Github.
The single board computer should be suitable for intelligent controllers and IoT gateways where dual Ethernet, WiFi and a human machine interface are required.
