I mentioned that Espressif were kind enough to send me a test board to play with – and very nice too. Not had time yet as I’m struggling with learning how to make an installer for my Node-Red package – with some great help from the guys involved with this….

So meanwhile here’s a lovely diagram – which I asked Espressif for specifically so you could see what the board does.

If you double-click on the image you will get a larger version. What’s really nice are the logical groupings. Not TOO keen on the tiny connectors on the right – but the main ones are 0.1” standard stuff. Quite looking forward to having a play.
