Radio module based spirit1.
N565AS SPIRIT1 module designed for 169M, 434M, 868M and 915MHz band. up to 16dBm output power and down to -118dBm sensitivity.
The SPIRIT1 module is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard. SPIRIT1 module supports an embedded CSMA/CA engine. SPIRIT1 module supports different modulation schemes: 2-FSK, GFSK, OOK, ASK, and MSK. Transmitted/received data bytes are buffered in two different three-level FIFOs (TX FIFO and RX FIFO), accessible via the SPI interface for host processing.
