An Arduino Nano-sized board based on nRF5340. Idea is to have modern and accessible alternative to a sea of nRF52840 boards.
- Similar, but not identical, pinout to Arduino Nano 33 BLE.
- Based on Raytac MDBT53-1M (nRF5340).
- USB-C connector.
- RGB LED.
- Uses TI TPS62291 for better efficiency. This also allows to use batteries in 2.3-6.0 V range (no on-board charger).
- Two buttons: Reset & User configurable.
- SWD pins on the edges.
- Chip antena for better wireless.
- Rather easy to solder this board at home.
- This board is not (yet?) available in Zephyr. Zephyr board definition from this repository should be used when building for this board.
- Board will be revisioned to improve & simplify design.
- Buck converter is used to improve efficiency, but maybe will be converted for LDO in next revisions.
- Bootloader is not required, but MCUBoot can be used as one. UF2 bootloader is not currently (15 Dec, 2024) available for nRF53.
- There are 0402 resistors in revision 0.1, which will be replaced by 0603(or even 0804) in next revision for easier placing & soldering.
