the LoLin32 Wemos is a more traditional than the Development Board Wemos mini d1 . With the LoLin32, Wemos abandons my concept of shields to stack (for now?). The Shields of the mini d1 are not compatible. We’re back to a format of Development Board for connected objects more traditional. Compared to the competition, the LoLin32 stands however slightly by proposing a LiPo battery connector. There is not yet information technical but it seems possible to charge the battery from the micro USB port. The connector is not specified but it seems identical to that of the shield battery ( presentation ), JST Connector XH2 – 2.54 mm . The page dedicated wiki is under construction.

The Wemos LiLo32 is now available on the official store of Wemos priced at €6,45 + postage (€ 8,10 in my case).
