Less than $1 USD.

That's how I like them, the board looks very decent too; I will order a couple.

You gotta love those Chinese: "Professional blue power light"; I also always have to laugh when a semi conductor is described as "Fashionable"

Thanks @rudy

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

But this was best post in any forums that fitted the best my problem.
I have also a CP2102 adapter which outputs 4.2V on the 3.3V rail.
The board is identical to the board featured in this video: https://www.youtube.com/watch?v=8qcGdB2yVd8
This is my board:

While checking on some signals I discovered I was getting 4.2V TX signal from my CP2102 based USB serial adapter.

Nevertheless I have corrected my development interfaces by cutting the track to the RST pin on the CP2102 module.

Was this the module you fixed? If so did you just destroyed the trace on the RST pin?
Would be nice if you could help me.
