Ran two of these on AA batteries for over a month in a greenhouse sensor setup, and the low-power draw is the real deal. The stackable radio header made wiring up the NRF24L01+ a five-minute job. Still ticking without a hiccup.

The compact size is exactly what I needed for my battery-powered sensor setup, and the stackable radio design means no messy wiring. It sips power off a single 1.5V cell, so I’ve left it running for weeks without swapping batteries.

Battery life is the standout here—it sips power from standard 1.5V cells, which is exactly what I needed for a remote sensor node. The compact footprint makes stacking the radio a bit fiddly, but it’s a fair trade for something this small.
