Powering ESP modules with fake FT232 adapter
Posted: Sun Mar 22, 2015 6:48 am
I have tried to power my ESP modules (ESP-01, ESP-03, ESP-07) in several ways.
There's no problem powering with batteries (1S LiPo or LiIon) or 3.3V regulator.
Powering with CP2104 USB to serial didn't work well, but when i use FT232RL adapter everything works fine.
The adapter that I've bought on e-bay has a counterfeit FT232RL chip (I did not know that when I bought it) and I was very upset when it got bricked with new windows driver.
I managed to unbrick it and use it with older driver.
Original FT232RL can supply only 50mA from its 3.3V regulator, so I was curious about regulator on fake FT232RL.
I connected 10ohm between 3.3V and GND output, and I'm happy to say that output voltage was still above 3.1V, while supplying more then 300mA!
So don't trow those fake FT232 adapters away, they are very well suited for our beloved ESP8266.
