[Product size]：19*12mm
[Introduction]：E01C-2G4M01S1B is a 2.4GHz SMD wireless module with a small size and built-in PCB antenna based on Si24R1. It uses an industrial-grade high-precision 16MHz crystal oscillator. The module's RF performance and component selection are in accordance with industrial standards, and the product has obtained authoritative certification reports such as FCC, CE, and RoHS at home and abroad, so users do not need to worry about its performance. Since E01C-2G4M01S1B is a pure RF transceiver module, it needs to be driven by an MCU or a dedicated SPI debugging tool.
