Product Description
SIM20
SIM20 is a high integrate half-duplex, multi-channel low power wireless communication module. It includes high speed MCU and perfect performance RF chip, so it has high receiving sensitivity, programmable transmitting power and data rate. SIM20 supports the multi-channel choice, transparent date transfer without complex user setting; it supports UART, IIC , SPI, GPIO interfaces.

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