Samuel Y. ★★★★★

This little board solved my battery power problem perfectly for an outdoor temperature sensor. The charging circuit works flawlessly and it fits snugly onto the D1 mini without any extra wiring needed.

Zoe ★★★★★

Bought this to power a battery-backed sensor node, and the charging circuit works without a hiccup—my D1 mini runs off a LiPo for days and recharges cleanly once the USB is plugged back in. The board's compact layout leaves plenty of room for wiring on the breadboard.

Aurora ★★★★★

The charging board sits flush on the D1 mini and the solder pads are nicely spaced, so wiring up a LiPo took me under five minutes. I’ve run a few battery-powered sensor nodes for a week straight and the voltage stays rock solid until cutoff.
