Ebyte E01C-2G4M11S CI24R1 11dBm 2.4GHz Wireless RF Module - SPI Interface
E01C-2G4M11S is a small size, 2.4GHz SMD wireless module with PCB antenna based on the core of Nanjing CSM Ci24R1, which uses industrial grade high precision 16MHz crystal.
Since E01C-2G4M11S is pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.
Features
- Maximum transmit power of 11dBm, which can meet the battery power and greatly expand the communication distance.
- Communication distances of up to 120m under ideal conditions.
- Support for the global license-free ISM 2.4 GHz band.
- Support for 2 Mbps, 1 Mbps and 250 kbps air rate.
- 126 communication channels to meet the needs of multi-point communication, grouping, frequency hopping and other applications.
- Connection to MCU via 2-Pin hardware SPI interface at 0 to 10 Mbps.
- Professional RF shield, anti-interference and anti-static.
- Industrial grade standard design, supporting long time use at -40 to +85°C.
- Self-contained PCB onboard antenna, no need for external antenna
