New ESP8266 with the size of a Mini Pro

[Jopiek]

Here you can find a board with the size of an Arduino Mini Pro. It does not have an usb connection so first time flashing with ESP easy is a little of an hassle but when your firmware is around 430kB in size OTA update is possible.

For flashing you will need a UART module.

For flash mode:
EN Pull up to V+
IO15 Pull down to GND
IO0 Pull down to GND

For running ESPEasy:
EN Pull up to V+
IO15 Pull down to GND
IO0 Pull up to V+

Hi,
Nice small card, watch for the 5v. connection, it's missing in the text.
Maybe 3.3 means power input.
But anyway, there is a 3.3v regulator on the board.

Robotdyne is until now the only supplier, as far as I can see.

It has a VIn for 4-9V powersupply. The onboard voltage regulator takes it down to 3.3V. I use the 3.3V pin and supply power with 2 x 2000mAh Nimh batteries through a step up converter. The onboard regulator I have taken of to limit power consumption during deep sleep.
