ESP8266 FIOR Mini Development Board - ESPFIOR

Released: July 2017, finished July 2015

This is a small development board for the ESP8266 ESP-01 IoT device. It brings out all the pins, has on-board 3.3V regulator, FTDI level-shifting for programming and updating the device (FTDI adapter required).

It fits perfectly on a breadboard, provides 3.3V ower pins for connecting other devices (sensors, switches, memory, etc.). It also has a reset button for quick rebooting instead of having to cut the power, furthermore you can reset the board by toggling the DRT pin in your terminal program!

Jumper pads to disable the LDO regulator externally and current measurement pads are available on the bottom side. A LiPo battery can be connected to a JST PH-connector for portable or field testing. USB charging option will also be available soon.

When you are finish prototyping on a breadboard, you can make the assembly very compact by dropping the pin socket and soldering the ESP-01 directly to the FIOR board - providing a very low profile with all the necessary pins still easily accessable.

This kit comes with the FIOR board and an unsoldered 8-pin socket.
