EdgeS3[D] - ESP32-S3 Reusable Dev Board with Dual Antenna

by Unexpected Maker

EdgeS3[D] is Unexpected Maker's brand new REUSABLE development board/module.

EdgeS3[D] uses an M.2 B-Key edge connector to allow you to insert and remove this module from a carrier PCB using an compatible M.2 B-Key socket. No more single use soldering of modules onto your boards while prototyping, which allows you to have less boards and move them between projects easily.

EdgeS3[D] also included is an onboard IO Expander with an additional 8x IO broken out to the connector, for those demanding applications that require just a few more IO..

EdgeS3[D] include everything you'd expect in a full featured board from Unexpected Maker - Onboard 3V3 regulator, battery charging and monitoring, excellent deep sleep and a finely tuned RF layout, it also has ESD protection for those of us that forget we are a walking static charge machine!
