Long Range Wireless Embedded UART Module in 865 to 870 MHz
This is a versatile, long range wireless embedded module which can be interfaced through UART to the host microcontroller. The module works as a high power RF transceiver, to transmit the data given through the UART. The module has UART data interface and do the RF communication at 865 MHz to 870 MHz. The integrated RF front end gives an output power of +24 dBm. Most of the RF and other network parameters can be configured on the module through the AT command interface which makes it flexible for use. The UART data transfer between the Host processor and the RF module is done with three handshaking signals (RTS/CTS/EOF). This module can be integrated with the host controller with little customization and minimum effort.
