nRF24L01 is a single-chip 2.4GHz transceiver launched by Nordic Semiconductor. It has ultra-low power consumption, long-distance transmission, multi-channel, etc. It is widely used in wireless mice, keyboards, remote controls and other portable devices.
The nRF24L01 is a single‑chip 2.4 GHz transceiver that integrates a baseband protocol engine (Enhanced ShockBurst™) and supports up to 2 Mbps air data rate. It operates from 1.9 V to 3.6 V and requires only an MCU and a few passive components, making it suitable for low‑power wireless designs.
The device offers 6 data‑pipe MultiCeiver™ channels, a built‑in voltage regulator, and 5 V‑tolerant I/O. Electrical specifications include 900 nA power‑down current, 22 µA standby‑I current, and 11.3 mA TX current at 0 dBm output. The chip is supplied in a 20‑pin 4 × 4 mm QFN package and complies with the worldwide 2.4 GHz ISM band (2.400‑2.4835 GHz).
