Compact and Powerful

The S3 chip handles multitasking well. Bluetooth LE works as expected for my sensor network.

Solid board

No issues so far. Wish it had a battery connector built-in though, had to solder one manually.

Good value but pins are tight

Works well with Arduino IDE. Pin headers are a bit close together for breadboarding without adapters.
