Pro Kit Power Supply Requirements

Does anyone know what the power supply requirements are for the pro kit with the Lolin Wemos D1 mini v4?

It appears it has a USB-C input. What voltage does it need from the power supply? How many watts does it draw?


For the D1 v4 we recommend 5v and at least 2.4A.

On the pro board that we start shipping now are two resistors next to the USB port. If you mount these you should be able to power the board from any USB C power source (eg usb c port from a laptop).
