Description

ESP8266 Adapter Board size is 31 x 28 x 3 mm.

2.54mm pitch breadboard friendly.

It is easy to solder.

There is no need to connect an external resistor between VCC and Chip enable.

Its weight is 4 grams.

The thickness of the PCB is 1.6mm.

The PCB color is white.

On the top layer of PCB is in black color.

10K pull-up resistor is populated on the PCB board.

It is compatible with the latest ESP-12F ES8266 Wifi Module.

On the bottom layer, there is a land-pattern for a 3.3V regulator.

To use a 3.3V regulator you will need to desolder 0-ohm jumper resistor R1.

The VCC pin then becomes 4.5V to 9V power input.
