In terms of wireless capabilities, TobuFi stands out with its dual Wi-Fi functionality. It incorporates the Qualcomm QCN9074 Wi-Fi 6 chipset, supporting both 2.4 GHz and 5 GHz bands with 2×4 MU-MIMO (2 transmit chains and 4 receive chains), and offers bandwidth options of 20/40/80/160 MHz. The module achieves an RF output power of up to 28dBm at 2.4 GHz and 27dBm at 5 GHz.

Furthermore, it includes the Qualcomm WCN9380 Wi-Fi 5, also covering 2.4 GHz and 5 GHz frequencies with 1×1 MU-MIMO and providing RF output power of up to 22dBm at 2.4 GHz and 20dBm at 5 GHz. This dual-band Wi-Fi setup ensures reliable and flexible wireless connectivity for a myriad of applications.

The TobuFi’s software environment is built on OpenEmbedded/Yocto, offering a comprehensive and adaptable development platform. This includes multiple Board Support Package (BSP) and application layers, as well as a range of development and upgrade tools. These capabilities facilitate seamless integration of TobuFi modules and enable the development of customized software distributions.
