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.

The resistor in the top left corner overheats when the battery is charging. *** I burnt my finger on it *** This happenes while chrcharging at 5.10V and 0.85A. There must be something wrong with the charging circuit design. A 2500mAh battery lasted just under one day while running the demo code.

Great module for developement. The screen is SSD1306 with 128x64 resolution. The wifi module works as expected, the battery protection and charging circuit is working great. Can only recommend.

nice wemos board with battery holder. not yet tested and programmed but as soon as I inserted the battery the unit start to show several shapes and words on the small display. satisfied, good quality bella scheda wemos completa di porta batteria al litio. non ancora provato, ma basta inserire la pila per vedere il programma installato che mostra alcune scritte e simboli sul display. soddisfatto

Jól működik, minden rendben van vele.

Összességében ez egy nagyon szép tábla, kivéve a bal oldali kapcsolót, amely csatlakozik a visszaállításhoz - nem biztos, hogy miért tűnt ez jó ötletnek, de mindenesetre megnézem, hogy van-e egy módja annak, hogy módosítsa a fórumon. Az alacsony nézettség azért van, mert az egyik a három tábla, amit rendeltem megérkezett OLED kijelző törött. A csomagolást, amelyet a finom kijelzőkhöz készített, egyáltalán nem volt túl jó. Ha megrendeli, azt javaslom, hogy győződjön meg róla, hogy kérjen megfelelő csomagolást annak érdekében, hogy az OLED kijelző ne sérüljön meg. Számos ember sérült kijelzők miatt rossz csomagolás.

Overall this is a very nice board, except for the joystick left connection which is connected to reset - not sure why this seemed like a good idea, but anyhow I'll look to see if there is a way to modify the board. My low rating for appearance is because one of the three board I ordered arrived with OLED display broken. The packaging by Banggood for these delicate displays was not done very well at all. If you order, I would suggest to make sure to ask for proper packaging to ensure the OLED display does not get damaged. There have been a number of people with damaged displays due to bad packaging.
