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, enabling a line-of-sight range of up to 800 meters. 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 5V tolerant, allowing direct connection to compatible microcontrollers such as those used with Arduino IDE. Internal filtering helps meet regulatory requirements. The radio uses Gaussian Frequency-Shift Keying (GFSK) modulation and features fast Automatic Gain Control (AGC). An Interrupt Request (IRQ) pin enables the host microcontroller to wake from sleep mode upon receiving data, supporting energy efficiency in battery-powered applications.
