Some weeks ago, Wemos announced a board based on the new ESP32 chip, named LOLIN32. This board hosts an ESP-WROOM-32 module and can be powered by a single cell (1S) LiPo battery. The board can also recharge the battery thanks to a circuit based on the TP4054 chip.
I brought a LOLIN32 board from Wemos’s official store on Aliexpress. The board is shipped inside an anti-static bag, with a label with your name:
The bag also include some pin headers:
Curiously I noticed that other Aliexpress stores sell boards named “lolin”. I brought one of them:
Although this board has the “wemos” logo printed on it, it actually looks like a clone of the D-duino-32 project by Travis Lin: unlike the LOLIN32 indeed this board does not include the LiPo battery connector and the charging circuit while it adds a 0.96″ OLED display.
Here’s a visual comparison between the two boards:
The advantage of purchasing an original Wemos card is the availability of the electrical schematic, some tutorials and a support forum… all that is missing for the clone board (how is the OLED display connected?). My suggestion is therefore that if you want to buy a Wemos board, you should get it from the original store.
If instead you are interested in a board with a OLED display, why not buy it directly from the designer’s tindie page, to support its development?
