Meet Qomu, the latest in the Tomu family of devices that fit inside you USB port. What’s different about Qomu? It’s not just an MCU, it’s not just an FPGA — it’s a complete SoC that fits inside a USB port. Qomu is differentiated by its vendor-supported open source tooling -– even the FPGA tools. The Qomu dev kit is the most capable tiny USB device, featuring QuickLogic’s EOS S3 multicore MCU + eFPGA SoC and its suite of 100% open source tools, including Zephyr, FreeRTOS, nMigen, SymbiFlow, and Renode.

MCU + eFPGA

The QuickLogic EOS S3 SoC on Qomu integrates an Arm® Cortex®-M4F MCU and an embedded FPGA (eFPGA), which means you can seamlessly blend firmware with gateware. Whether you need an accelerated machine learning classifier or glue logic for a new peripheral, the EOS S3 SoC puts you in control of making fine-grained design tradeoffs. Qomu is the perfect EOS S3 dev kit to get started — slot it into any USB Type-A port and take your project development with you everywhere you go.

100% Open Tools

Target Qomu’s eFPGA with SymbiFlow 100% open source tools for synthesis, place and route, and bitstream generation. Many example applications and gateware are available to try out completely free. And you don’t need to be a Verilog expert to use the eFPGA; in addition to standard Verilog support with SymbiFlow, Qomu supports nMigen for a Python-to-FPGA design flow. Both Zephyr and FreeRTOS real-time embedded operating systems support Qomu, and full device simulation is available with Renode.
