This board (60x60mm) is the basis for developing products with the ESP8266 processor. Thanks to the smart connections between the soldering islands, the electronic components as well as sensors and other modules always find a place on the 1of! -Proto board.Suggest adaptation
The 1of! -Proto board has a 20-pin connector that connects to the expansion port of a 1of! -ESP12 or 1of! -Wemos processor board. The experimental space has six power or data lines along its length. Four islands are always connected across the width. Optionally, you can solder two LEDs on the 1of! -Proto board connected to the 5-volt and 3.3-volt power supply lines.
