Additional Details

The SI2403-FTR operates in the sub-GHz frequency range, offering excellent range and penetration compared to higher frequency bands. The integrated modem handles data encoding, decoding, and packet handling, simplifying the software development process. The programmable output power allows for adjusting the transmission range to optimize power consumption. The device also features a wake-on-radio function, enabling the receiver to remain in a low-power sleep mode and wake up automatically upon receiving a valid signal, further extending battery life. The small package size makes it suitable for compact and space-constrained applications.
