[CNX-Software] - Romu – A Tiny Raspberry Pi RP2354A board for USB application development (Crowdfunding)

Bitmerse Romu is a tiny (15.5 x 12 mm), almost minimal Raspberry Pi RP2354A USB board with a USB 2.0 interface on one side of the PCB, and the dual Cortex-M33/RISC-V MCU on the other side, connected to a few debugging/programming pads, buttons, and an RGB LED. It doesn’t come with any GPIO, and it’s mostly designed for USB applications such as a security key for passwordless login, a USB MIDI controller, a macro pad, or a custom HID device. You can plug it directly into a spare USB Type-A port of your computer/host without any cables, breadboard, or adapters required. Romu specifications: SoC – Raspberry Pi RP2354A CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot Dual-core 32-bit RISC-V Hazard3 @ 150 MHz (3-stage in-order pipeline; RV32IMAC with Zba, Zbb, Zbs, Zbkb, Zcb, Zcmp, and Zicsr extensions) Up to two cores can be used at a time, either 2x [...]
