I’m going to tryout my ESP32 Super mini and I thought I would share this photo I just took showing three boards for comparison of their size.

From Left to right : Arduino Pro mini, ESP32-C6 Super mini and ESP-WROOM-32 ESP32/ESP-32S Development Board.

These boards are being using to test out low current interfaces or WiFi/BT powered projects directly from the USB port or adapter cable in the case of the Pro Mini.
