You sure GPIO2 resistor is pull-down? I think that will interfere with flash and/or normal boot.

You are right, I was wrong. The pull-down is on GPIO15. I'll edit my initial posting.
Thank you!

- Wed Jan 13, 2016 5:56 pm #38717 The 0 Ohm resistor is a bypass for the SOT-89 voltage regulator. Some boards come with a higher resistance, which I've just left in place. I've soldered in an HT7333 linear regulator and removed the 0 Ohm resistor. Works fine from a 5V supply now. I soldered a 22uF tantalum cap across the regulator's Vin and GND lines. Not sure if the ESP8266 module has input decoupling capacitors (eliminating the need for a tantalum cap across Vout and GND), but it should.

They are wide, but you can pre-wire the breadboard and put the adapter plate on top. Like so:

Or you can use them with two breadboards put side-by-side.
