ESP8266 Community Forum

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.

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.

i agreed

I'd also recommend not soldering the power LED on.

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.
