Flashing the un-flashables

Post by Electroguard »

I have a Wemos D1 Mini with a faulty onboard regulator, so it cannot be connected to USB for re-flashing or for power.
No need to throw it away though, cos it has 3.3v pin allowing it to be powered from elsewhere, and TX, RX and gpio0 pins allowing it to be re-flashed using an external serial UART (FTDI adapter)... which can also supply it with power for re-flashing.

That highlights something worth remembering... if your OS fails to load the appropriate serial drivers for a particular ESP device, simply flash it using your good old faithful external FTDI adapter which it does already have the drivers for (if you can still remember how to use it!).
