 The button is not connected to GPIO00 so flashing the unit requires some extra work. I managed to flash the iFan02 by soldering a wire to TP16 (GPIO00) on the bottom of the PCA. While connecting this wire to Gnd and also keeping the button pressed when applying power to the unit it will be in firmware upgrade mode.
 
+If you have an Arduino you may be able to flash without providing an additional power source. I have successfully flashed using an Arduino Duemilanove with the atmel chip pulled out (basically using it for FTDI and 3.3v power regulation). Rx on Arduino goes to Rx on iFan02, Tx to Tx (no crossover like with FTDI). I did not have to press the button, only to ground TP16 while initiating the flash in Arduino IDE. The Arduino provides enough power to flash, however it will not boot into Tasmota unless you plug in to external power (it boot loops after flashing is complete).
