There is no documentation to install the Adafruit. Most users go the simple route and upgrade the display with one we sell. The Adafruit product uses the i2c bus, you will need to Connect 5v to 5v, GND to GND, SCL to SCL, and SDA to SDA. Your LCD may have a second header for i2c where you can solder another set of pins.

Hi all, I have V4 board with 40A relay with 3.11.3 firmware.
Sometime I have a display bug with my charger. You can see on the picture.
When this appears, the charger still working.
But one time last week, the charger stopped and I saw this bad things
Have you any idea about it?
