8devices TobuFi SoM is designed for drones, robotics, and advanced audio systems

8devices has recently introduced TobuFi, a Qualcomm QCS405-powered System-on-Module (SoM) featuring dual-band Wi-Fi 6 and Wi-Fi 5 capabilities. The device also features 1GB LPDDR3, 8GB of eMMC storage, and multiple display resolutions. It also offers various interfaces, including USB 3.0, HDMI, I2S, DMIC, SDC, UART, SPI, I2C, and GPIO.

In previous posts, we covered 8devices product launches like the Noni M.2 WiFi 7 module, Rambutan and Rambutan-I modules, Habanero IPQ4019 SoM, Mango-DVK OpenWrt Devkit, and many more innovative products. If you’re interested in 8devices, feel free to check those out for more details.

8devices TobuFi SoM features Qualcomm QCS405, dual-band Wi-Fi 6/5, 1GB LPDDR3, 8GB eMMC, and interfaces like USB 3.0, HDMI, and more.

While I was looking at the specifications, I wondered why the SoM features two radio modules. It turns out that the QCN9074 radio module provides a host of neat features. It operates on dual-band 2.4 GHz and 5 GHz frequencies with a 2×4 antenna setup and supports extended frequency ranges from 2312-3000 MHz and 4900-5925 MHz. This setup is crucial for that 5/10MHz narrow bandwidth support that extends the range of the device to 10 kilometers and beyond.

The module also reduces channel steps to 1 MHz for both the 2.4 GHz and 5 GHz bands, enhancing precision in frequency selection. Furthermore, it uses non-standard center frequency channels to minimize interference, enhancing the stability and reliability of wireless connections for various applications.
