NewMsg-RF905 Development Guide, introduces the characteristics of NewMsg-RF905 module, including working frequency, working speed, number of channels, power consumption, receive and transmit mode, interface circuit pins, etc.
This guide introduces the NewMsg RF905 series modules (RF905SE and RF905B), describing their physical dimensions, key features, and typical applications in wireless communication. It details the pinout, electrical specifications, and recommended connections for microcontroller integration.
The document explains the four operating modes (ShockBurst TX/RX and standby/power‑down), the SPI configuration process, and includes a FAQ section addressing common integration questions such as the proper use of the CSN pin. This manual is written in Chinese.
| Operating Voltage (minimum) | 3.0 V |
|---|---|
| Maximum Transmit Power | 10 dBm |
| Maximum Data Rate | 50 kbps |
| Receive Mode Current | 12.5 mA |
| Power‑Down Current | 2.5 µA |
| Operating Temperature Range | -40 to +85 °C |
No, CSN is the SPI chip‑select line and must be driven high for the RF905 to accept data.
The module draws about 2.5 µA in power‑down mode.
