Category: Shields

The WeMos lithium battery shield provides a means of powering your WeMos mini, or WeMos mini Pro (see item HCWEMO0002) from a single cell (3.7V) lithium battery. The shield contains a DC-DC converter to step-up the batteries 3.7V to 5V supplying your WeMos mini and shields with up to 1A of power. When the battery is depleted simply plug the shield into a USB power source using a mini USB cable and it will automatically recharge the battery. Two LEDs on the shield indicate when the battery is charging and when charging has completed.

Sebastian ★★★★★

Perfect for my outdoor sensor project—the integrated DC-DC converter means stable 5V output even as the battery drains. It’s nice not needing extra wiring or voltage regulators.

Matthew ★★★★★

I've got two of these now to run outdoor sensors, and the DC-DC converter means I can use any old 18650 cell without worrying about voltage spikes. The shield fits flush on the D1 Mini with no extra wires needed.

Aurora ★★★★★

The DC-DC converter keeps my D1 Mini running steadily off a 3.7V cell, which is exactly what I needed for a portable sensor project. Soldered it on in under five minutes and haven't had a single power hiccup since.
