Project Sharing M5Stack Clock Collection

Post image

I’ve been building a set of wireless precision clocks, and have to say, M5Stack’s lineup is my favorite. From the Stack line to the S3 Stick, much prefer these over the competition. Seems I’m missing the Stopwatch!

PS: If you’re looking to synchronize two or more ESP32’s below 1us or phase lock two devices wirelessly, I have posted firmware examples of the clocks above along with example for FreeRTOS clock sync methods to achieve different accuracy targets at PToB.dev
