Here are ideas for the next generation of the Grove Beginner Kit for Arduino.
- Use a more powerful MCU, eg. a Cortex-M0+ like in the Seeeduino Lotus Cortex-M0+.
- Expose the SWD signals for debugging, already in place in the Seeeduino Lotus Cortex-M0+.
- provide the tools and tutorials for debugging. I like the very affordable Segger Edu mini with the excellent GUI debugger Ozone.
The main is to provide an affordable solution to learn debugging, as it is an important part of development.
