[Swansea Hackspace] ESP32

[Justin Mitchell]

I note that ESP32 dev boards are now appearing on aliexpress,
in the NodeMCU style like the cheap ESP8266 ones we now stock.

They appear to be in the £18-20 each range for the moment.
e.g. https://www.aliexpress.com/item//32758840305.html

I know these are faster, more memory, and have bluetooth as well as the
wifi, but what was it that people wanted to learn about them?
ie what topic could a workshop be run on ?
