This Wireless Transceiver module offers a balance of performance and cost-effectiveness for wireless communication systems. It is compatible with common microcontrollers including MCU, ARM, PIC, AVR, and STM32. The NRF24L01+ module features an integrated power amplifier and SMA antenna, supporting wireless communication up to 800 meters in open space. Communication and configuration with a host microcontroller occur via a 4-pin Serial Peripheral Interface (SPI). Configuration registers are accessible through the SPI interface. Adjustable parameters include channel frequency (125 selectable channels), output power, and data rate (250 kbps, 1 Mbps, and 2 Mbps). The on-chip voltage regulator supports supply voltages from 1.9 V to 3.6 V. Input pins are 5 V tolerant, enabling direct connection to compatible microcontrollers. Internal filtering helps meet RF regulatory standards. The radio uses Gaussian Frequency-Shift Keying (GFSK) modulation and fast Automatic Gain Control (AGC). An Interrupt Request (IRQ) pin allows the host microcontroller to wake from sleep mode upon receiving a transmission, improving energy efficiency in battery-powered applications.
