The EFR32 module is our latest low-power, high-performance SOC wireless transceiver module. It is developed based on SILICON’s EFR32FG14. It adopts advanced direct sequence spread spectrum communication modulation technology (DSSS), and higher performance 32-bit ARM®Cortex®-M4.
The EFR32 module is easy in the secondary development of the module. The traditional wireless module is that the wireless transceiver chip and the MCU are independent of each other, and the MCU needs to control the wireless transceiver chip to transmit data wirelessly through SPI/IIC and other methods. The secondary development of EFR32 directly skips this cumbersome step, and can call the wireless library function when using the wireless function, which greatly accelerates the development progress.
