RF Module Sim20

Product Specifications /Features

SIM20 is a high integrated half-duplex,multi-channel low power wireless communication module. It includes high speed MCU and perfect performance RF chip with high receiving sensitivity, programmable transmitting power and data rate. SIM20 supports the multi-channel choice, transparent date transfer without complex user setting and UART(CMOS/TTL),RS232RS485IIC/SPI,ADC interface.

The leading features of the module make it ideal for industrial applications such as automatic metering,wireless medical telemetry service,home automation,process and building control.
