The WiFi IR Blaster includes a
3.3V low dropout regulator
which can supply up to 600mA and handle voltage
inputs up to 6V. To use this regulator, connect your power source to the
VIN pin
.
Alternatively, a pair of 3.3V pins are broken out on both headers. This pin directly supplies the ESP8266, so it
should remain regulated to the range of ESP8266: 3.0V-3.6V.

Powering via FTDI Header
The WiFi IR Blaster can be powered via the 3.3V pin on the 6-pin serial header. Voltage supplied to this pin
should be
regulated to 3.3V
. Your power source will need to be able to
supply at least 300mA
, which most
FTDI boards cannot do. We recommend the Beefy 3 FTDI Basic Breakout which can supply up to 600mA.
Removing the Standoff Edge
A pair of standoffs are provided towards the bottom of the WiFi IR Blaster. If you don’t need these standoffs, and
want to save some space, the standoff board can be removed by breaking it along the v-score line.

Programming the ESP8266
The WiFi IR Blaster’s ESP8266 is designed to be programmed with a 3.3V FTDI Basic or a similar 6-pin USB-to-
Serial converter. We recommend a Beefy 3 FTDI Basic Breakout if you’re powering the Blaster with the FTDI (see
the note in the previous section for more information).
Plug your USB-to-serial converter in making sure you match the “GND” and “DTR” signals on the edge.
