The Wemos LoLin32 is a more traditional development card than the Wemos d1 mini. With the LoLin32, Wemos abandons (for now?) His concept of shields to stack. The Shields of the d1 mini are not compatible. It returns to a format of development card for more traditional connected objects. Compared to the competition, the LoLin32 stands out however slightly by proposing a connector for LiPo battery. There is still no technical information but it seems possible to charge the battery from the micro USB port. The connector is not specified but it looks identical to that of the shield battery (presentation), connector JST XH2-2.54mm. The dedicated page of the Wiki is under construction.

A very important point, the LoLin32 is narrower than the competing boards. It leaves free a row of connector on each side on the breadboard

The Wemos LiLo32 is available now on the official Wemos shop for €6.45 + shipping (€8.10 in my case).
