Hi all — I'm developing a custom nRF5340 development board (Raytac MDBT53-1M) and would value the community's honest read on whether it's worth producing.
The goal is a board optimized for the flash–debug–power-profile iteration loop, using open-source tooling.
Key features:
- Onboard CMSIS-DAP debugger (RP2040 + debugprobe firmware): full SWD flash and live debug over USB-C, working directly with probe-rs, OpenOCD, pyOCD, and the nRF Connect SDK / Zephyr toolchain.
- Current measurement without board modification
- LiPo charging with load-sharing power path for battery-powered prototyping.
- Arduino-compatible + dual GPIO headers, Qwiic, USB-C, NFC connection.
Intended price: ~$44*
To be clear, the DK is excellent. What I'm testing is whether out-of-the-box measurement, open CMSIS-DAP tooling, and battery charging are worth anything to people here, or whether the DK already meets your needs.
Would this fit into your workflow? What would you change or add? If you'd want one, I'd appreciate a note here or a signup on the waitlist so I can gauge whether to do a production run: forms.gle/V1ZPMtDSSYrA95TK9
Thank you for any feedback.
