This development boards has two rows of 14 pin 0.1” headers with the I/O shown in the image. The header spacing is 0.7”, enough to give you two empty rows of pins on either side of the development board when inserted into a standard bread board.
The overall dimensions are 0.8” X 1.6” including the wi-fi antenna, that is right, this is a breadboard friendly ESP32 C6 with a full side wi-fi antenna for exceptional signal strength.
It is based on ESP32-C6-MINI-1-N4 microcontroller.
