The TX433-JK-11 with Wireless Modules 110mmx9mm RoHS is an electronic component manufactured by ZIISOR. It is a compact, low power radio transceiver with the frequency band of 433MHz. It is specifically designed for use in telemetry applications, devices for remote data-collection, and wireless control systems. It provides an unparalleled transmission range of up to 1000m in LOS (Line of Sight) conditions. The radio operates in half-duplex that enables two-way communication with low power by using a low data rate (up to 250kbps air data rate). It is also equipped with advanced RSSI and packet store/forward capabilities that allow communication even at long distance, through trees, buildings, and other obstacles. The device measures 110mmx9mm and is RoHS compliant.
