ESP8266 ESP-12 breadboard adapter enables you to use popular ESP-12 modules with standard solderless breadboards with 2.54 mm (0.1 inch or 100 mil) clip raster.

It’s targeted mainly for designers who want to quickly test their ESP8266 prototypes and do not need complicated ESP8266 kits. The main idea was to create fully featured breadboard adapter that includes only components usually present across all ESP designs (but even these are optional) and puts absolutely no constrains on your project.

Following goals are achieved:
  • Every single pin of ESP-12 module can be used. That includes SPI interface and GPIO9 / GPIO10 available on ESP-12 E and F versions.
  • It’s ready for optional THT pull-up / pull-down resistors for RESET, CH_PD, GPIO0, GPIO2 and GPIO15 pins.
  • All signals are available at uncovered breadboard tie points. As a result you don’t need to route all signals before plugging adapter into breadboard or remove adapter to route a new signal.

Kit consist of:
  • PCB board (characteristics below),
  • set of THT pull-up / pull-down resistors,
  • set of pin headers.
ESP8266 (ESP-12) module is not included. All items in the kit need to be soldered to the PCB.
