Overview

The NRF905 is a high-performance RF module operating at 433MHz, designed for low-power, long-range wireless communication between microcontrollers (Arduino, STM32, ESP8266). With SPI interface and configurable channels, it’s ideal for remote sensors, IoT, and wireless control systems.

Description

Key Features:

✔ 433MHz ISM Band – Long-range (up to 500m in open areas) with external antenna. ✔ SPI Interface – Easy integration with Arduino, Raspberry Pi, STM32. ✔ Configurable Channels – 126 frequency steps (avoid interference). ✔ Low Power Consumption – 1.9–3.6V operation, sleep mode for battery savings. ✔ High Speed – 50kbps max data rate (adjustable). ✔ Built-in CRC & Auto Retransmit – Ensures reliable data delivery.

Applications:

Wireless Sensor Networks – Weather stations, soil monitors.
Remote Control – Drones, RC cars, smart home devices.
Industrial Telemetry – Machine data transmission.
DIY IoT Projects – Replace Wi-Fi where coverage is weak.

Pinout & Wiring (SPI):

VCC → 3.3V (1.9–3.6V range).
GND → Ground.
SCK, MOSI, MISO, CSN → SPI pins of MCU.
CE, TX_EN, PWR_UP → Control pins.

Technical Specifications:
