- Tue Jun 30, 2015 9:21 am #22058 Hi everyone, I've explained on my blog (italian language, no spam) how to make available all 10 GPIO on ESP-01, adding 6 more pins to the board:

The trick is possible soldering wires to the pins indicated here. Each one is an extra GPIO. The #5 is not really handy, but it is usable anyway.
Final result:

I don't mean to sound negative, but what is the point?

Someone with poor soldering skills and poor eyesight will simply short pins. Why not just use an ESP8266-12?

Or falling that if ESP8266-01 is the option and they have loads of them like me, simply use an I2C bus expander, a much more elegant approach.

Well done on your soldering though, takes a good eye to solder these tiny pins to wires

You can solder ADC input to TOUT pin.
So it will be 10 + 1 (input).

BTW: clean solder flux before doing a photo pls

Dan, the point is that some times you need more io and buying a bigger module will mean 30 to 40 days waiting in the mail.
