iSpindHub

Overall Project Information

This project is widely inspired by TiltBridge and Nautilis' iSpindel Relay.

Easiest way to install is through BrewFlasher, project is iSpindHub.

It is basically a receiver to get information from your iSpindels and display it allowing you to use your iSpindel(s) even if you do not have WiFi available in your brew cave.

It also acts as a WiFi repetiter and will push iSpindel information to various services (BrewFather, LittleBock, CraftBeerPi etc).

Generic stuff

I will try and list the various screens I have tested and am sure are working (this might lead to multiple releases unless I find an elegant way to have this as a selectable option) I might have to rewrite my code to use a generic library and not a specific one ...

1.4 TFT Screen

This one is an easy to find on Ali Express and is nice because it plugs directly onto a D1 Mini. Display is square 128*128

/!\ I have not tested it (recently) directly plugged onto the D1 Mini. I used the bottom connection and soldered pins.
