NewMsg-RF2411 is a 2.4Ghz wireless communication module which supports ISM band and allows modulation in FSK or GFSK, and the transmission speed can be 1Mbps or 2Mbps. The output power is programmable from -35 to 5 dBm.
The NewMsg RF2411 is a 34 mm × 17 mm wireless module operating in the 2.46 GHz ISM band. It supports FSK and GFSK modulation, offers data rates of 1 Mbps or 2 Mbps, and provides programmable output power levels from -25 dBm to +5 dBm. The module runs from a 1.9 V to 3.6 V supply and features low‑power modes, including a 3 µA power‑down current.
This programming manual describes the module’s pinout, hardware interface, internal architecture, and four operating modes (TX, RX, standby, power‑down). It includes detailed register tables, SPI command sequences, and example code for configuring and using the RF2411 in embedded applications. This manual is written in Chinese.
