Electronics Evening 13th Oct

#1

Hi Guys, I’m looking to be down tomorrow for electronics evening, will bring the normal bits and bobs, Arduinos, ESP8266, STM32’s etc
Has anyone got any special requests or is it just a tinker night ?

yea that looks like it.

these look good too For breakouts.

#7

I like those too. Takes a 5v input from a phone charger, built in USB, dirt cheap. I buy them by the dozen via AliExpress.

#8

Is it possible to remove the ESP-12 from the NodeMCU and put an ESP-07 in its place?

#9

I used these before I made my own, they have a space for an onboard regular if required and the two pull up resisters onboard

@andrew_d it is possible using the hot air gun and liquid flux… it’s high risk and the old esp-12 won’t make + you have to be very careful of components on the bottom of the board… would it not be better to buy a USB breakout and solder an esp-07 to it ?

That’s what I am doing at the moment. However, it is not as neat as the NodeMCU, and programming is not as simple as plugging in the USB.

Cool, Happy to have a go at swapping it Thursday if you want…

I can’t make Thursday evening sessions for a while, due to a degree I am doing by evening study. I also do not have any ESP-07s spare at the moment.

Thanks for the tip. Up and running in no time.
