Good value, but check visually before turning on!

Overall I am happy with this product, the price was good and the delivery was fast. The only problem is that you need to check that the pins on the I2C board are not shorted to the back of the LCD board. What I got was a short between one of the pins of the 4 pin header (the I2C board) and a solder joint on the back of the display board. main problem; There wasn't enough spacing between the boards to accommodate the length of the connector pins on the back of the I2C board. To fix the problem without soldering all the pins on the board, I inserted insulating material (thin insulating sheet) between the pins of the 4-pin connector and the LCD board.

Pros
