Flashing using only a USB to serial converter will not work as the unit draws too much current as can be observed by a flashing blue led on the PCA and a lot of serial gibberish. As AC is not connected to Gnd I used the available power supply of the unit and connecting the USB to serial converter to J3 pins Gnd, Tx and Rx.

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. Keep this wire connected to Gnd during the power-on or reset process (pressing the button) and the unit will be in firmware upgrade mode. If you've soldered the gpio0 connection don't forget to unsolder before booting normally. The button is not connected to GPIO0 so flashing the unit requires some extra work.

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).
