nRF24L01 2.4GHz 無線電收發模組

The power consumption is incredible—I've been running a sensor node on a coin cell for weeks without changing it. With a 2Mbps data rate, my Arduino projects are talking to each other faster than I expected for such a small module.

These modules are sipping under 14mA during transmit, which let me build a remote temperature reader that runs for months on two AA batteries. The 2Mbps data rate is plenty fast for my sensor data, and pairing them was surprisingly straightforward.

Got these running in a low-power sensor node and the sub-µA standby current is exactly what I needed for battery life. The 2Mbps data rate also handles my telemetry bursts without any packet loss. Wired up and talking to the Arduino in under ten minutes.
