Specifications
Wireless RF module 315MHz / 433MHz /470MHz / 868MHz / 915MHzISM Band FSK module
low cost and small size
data rate 250kbps
FC-RF1023RF Transceiver is a compact surface-mounted half-duplex FSK module.It is a low-cost small-size wireless module with SPI for embedded applications. There is an external 128 bytes EEPROM to save the data used for frequency calibration. MCU will read the data in EEPROM After power-on to calibrate the frequency.It contains 64 byte FIFO buffer, which can relieve the MCU's load while processing the data. This makes it possible for a low-cost MCU to implement high-speed data transmission task. The RF data rate can reach 150kbps. The module with optional FEC , CRC and Manchester encoding can realize stable and reliable data transmission in busy ISM band. The module is completely shielded and designed for operation under the European and US radio regulations for license-free use.
Main Applications:
- Intelligent home control system
- Wireless RFID tag
- Wireless sensor
- POS terminal
- Industrial data transmission
- Automatic data collection system
- Wireless remote control
- Wireless AMR for water, gas and hot, electricity and other meters.
