Radiocrafts AS RF Transceiver Modules and Modems RC1210

The RC1210 RF Transceiver Module is a compact, surface-mounted device designed for 25 kHz narrow band FSK operation, featuring an embedded protocol. It measures 12.7 x 25.4 x 3.7 mm and is fully shielded, making it suitable for OEM applications, radio modems, alarm systems, point-of-sale terminals, barcode scanners, telemetry stations, and fleet management. This module operates within the frequency band of 418.725 to 419.450 MHz and supports up to 30 channels with a channel bandwidth of 25 kHz. It has a maximum output power of 8 dBm and a sensitivity of -112 dBm. The RC1210 is designed for low power consumption, with a current draw of 20.2 mA in receive mode and 26 mA in transmit mode, while achieving a sleep current of only 0.9 mA and an off current of 3 nA. The module features a simple UART interface for easy integration, a 128-byte data buffer, and requires no external components for single-channel use. It operates over a wide supply voltage range of 2.8 to 5.5 V and conforms to Chinese regulations for license-free bands. The RC1210 is suitable for applications requiring reliable wireless communication over distances of 1-2 km with appropriate antennas.
