CGM Freestyle Libre Link Up Abbot ESP32

Hello

Made this “tiny” tool for my kiddo since she always "forgot" to check it before sleeping to make the correction if needed.

Recycled my Air Quality Monitor project and it came pretty well.If you want you can run it with a battery and soon I'll post the slimmer case for just the TFT 2.0 inches and ESP32C3 no expansion board and battery

It works using the Freestyle Libre sensors and the online account(the one you use for the APP via mobile)

You need

ESP32C3 Supermini super cheap from aliexpress https://pt.aliexpress.com/item/1005007941259180.html? paid below 2euros

Expansion Board (not mandatory) you can solder your battery's cable under of the esp32 https://pt.aliexpress.com/item/1005010643172397.html paid around 1euro

TFT 2.0 IPS Screen https://pt.aliexpress.com/item/1005006423091182.html used to pay around 2/4 euros

Li-Po 3.7v, I'm using 2000mAh around 24hrs https://pt.aliexpress.com/item/1005009590723370.html paid around 8euros for 3pcs

Some AWG and dupont cables

As you can see it's a pretty cheap project but useful for those who needs it
