This version is the first that gets flashed on the purchased devices
If you had a device you built yourself this changes the wiring setup from SPI to I2C native.
Breaking changes
With this version, we introduce the use of native I2C and drop SPI if you have a device with a lower version than v4.0 don't update since your reader won't work anymore and you will have to change the wiring.
Fixes
- Some devices had issues connecting to the wifi and were dropping the connection. This shouldn't be the case anymore
