The APC802 radio module provides a simple and economic solution to wireless data communications. The employment of an embedded high speed microprocessor and high performance IC creates a transparent UART/TTL interface, and elminates any need for packetizing and data encoding. It is a updated version of APC220 which provides up to 2800 meters communication ranger (line is sight). Also, it supports RS232,TTL, RS485 interface.
