|Mini-breadboards or DIY ESP Development Board?|
What do you do when you can't wait for cheap breadboards to arrive from China? Build a development board of course!
The picture shows the work of an afternoon, to make a dev-board for the ESP-12 "IO Adapter Plate Expansion" (ebay) soldered up last time, which inconveniently didn't fit any breadboards around the house.
The circuit is based on this one except that it's powered from the FTDI cable.
The following week the mini-breadboards arrived. Haven't used them yet!
