this is a breadboard  for the LOLIN NodeMCU  Development Board ESP8266-12E for Arduino IDE see other listing (the nodemcu is not included)

please note this has a pin spacing of  28MM between the rows  unlike the unit made by DOIT witch  is  23 MM

this is compatible with the LOLIN NodeMCU not the DOIT device

this is just the breadboard the last picture just shows the NodeMCU to show how it fits togather
