CSM Si24R1 + Geochip GC1101 2.4 GHz Module

The RC24R1AP is a general-purpose low-power, high-performance radio frequency transceiver module developed by RF Crazy technology. It integrates a 2.4 GHz radio frequency transceiver Si24R1 and the radio frequency front-end chip GC1101, which is designed for low-power long-distance wireless applications.
The operating frequency range of RC24R1AP is 2400 MHz ~ 2525 MHz, supports GFSK/FSK digital modulation and demodulation, and the data transmission rate can be adjusted, supporting three data rates of 2 Mbps, 1 Mbps, and 250 Kbps. Transmit power +20 dBm (adjustable), receive sensitivity: -83 dBm @ 2 MHz, RC24R1AP is specially optimized for low-power applications, in the shutdown mode, the current is only 1 uA; in the standby mode, the current is 15 uA, and the data transmission and reception can start within the longest 130 uS time.
The RC24R1AP has a very low system application cost, and only one MCU and a small number of peripheral passive devices are required to form a wireless data transceiver system.
