Posted May 17, 2025 at 3:15 am · in Bare ESP-WROOM-32 modules on our own little board: what’s the minimum around them? #5

Board rev 1 came back from the fab last week. 9 of 10 boot and report to Hermetry, the tenth had a solder bridge. My first attempt had no capacitor on EN and two boards only started when I touched the pin, exactly like you said. Programming with the CP2102 adapter and a pogo clip now.

Noted! Power would be a 5 V USB phone charger in the wall socket, there’s one near every desk.
