Product as description. Function test was not ok as I found out the oled is cracked. This happeh due to poor packing and rough handling during transit. Seller is saving money and the percentage of “dead on arrival” is increasing. On long term is not a good approach. Customers will stop buying often as the risk of receiving a damaged item increased significantly.

Very nice development board with joystick input button and oled lcd. Take care when inserting the battery, there is no protection and the regulator chip will explode as you see in the attached pictures. The impact was so severe a part of the charging chip exploded, you even see the crate in the chip in the last picture. It was my fault but I subtract one star for missing polarity protection on the input. The rest of the board is great, I could not drive the board with the Adafruit oled library but I found a replacement oled library which works.
