#3242 I designed these boards over the weekend to make the ESP-03 a little easier to work with for quick projects, and was wondering if anyone else would be interested in these. The ESPuino (terrible name, I know) is breadboard-compatible and has a voltage regulator for higher voltage power sources, and the ESPBee is pin compatible with the ZigBee. The ESPuino also has the pin functions printed on the bottom silkscreen - The 5-pin header on top is for an FTDI programmer.

If there's any interest, I can also add a reset button (that would work by disconnecting power while pressed) and some DIP switches to put the chip in firmware flashing mode.

#3247 its good. you can add reset and firmware mode switches.
i think ams1117 wrong choise for low power operation. it consume 2-3ma on iddle mode. maybe you can change ams1117 with ldo(low drop voltage regulator)

Thanks. What did you have in mind, something like the MIC5219-3.3? I picked the am1117 since it'll provide up to 1A and is very cheap. Also, by supplying 3.3V directly to the 3V3 pin, you can bypass the regulator entirely - If used for low-power purposes, I'd also recommend not soldering the power LED on.

#3250 i agreed

like this. but i cant see idle power consume on data sheed
MIC5219-3.3

ldo for direct battery powered applications. like send data on the web and sleep every minute.
