Arm® Cortex®-M4F + eFPGA SoC tiny form factor dev kit fits in USB Type A port found on almost every computer, enabling portability and development anywhere

Qomu development kit is a tiny form factor Arm® Cortex®-M4F MCU + eFPGA combination that fits into a USB Type A port. It features QuickLogic’s EOS S3 multicore MCU + eFPGA SoC. Optimized for the QuickLogic Open Reconfigurable Computing (QORC) Initiative, the kit is supported by open source development tools, including Zephyr, FreeRTOS, SymbiFlow and Renode. Qomu also supports nMigen for a Python-to-FPGA design flow.
