YS­1020UB RF Data Transceiver
YS­1020 series Low power RF modules designed for the professional UART data transmission systems in
short range. YS­1020 adapt Texas Instruments (Chipcon) CC1020 RF IC, works on ISM frequency band, half
duplex integrated receiving and transmitting. Modules could directly connect with monolithic processors, PC,
RS485 devices, and other UART components with RS­232, RS­485 and UART/TTL level interface port.
Transparent data interface, nakedness, and wide temperature design handles most industrial application though
indoor/outdoor environments.
