ESP32-S3 (WROOM) Small Dev

Minimalistic breadboard friendly small dev board for ESP32-S3-WROOM-1 modules

• 2 layers
• 12uA current in deep sleep (using ESP-IDF deep sleep example)
• weak, but typically sufficient, voltage regulator (constant current 250mA, pulsed current 550mA)
• PMOS for reverse polarity protection on VIN
• Arduino IDE compatible pin names for I2C and SPI

See https://oshwlab.com/Miraculix200/esp32-s3-mini_copy for a circuit with more powerful voltage regulator

Names next to the pin numbers were taken from the Espressif Arduino IDE repository (ignore the wrong numbers in the photos, which have been updated).
