STMicroelectronics Low Data Rate Transceiver Daughterboard Sub GHz SPI Interface 915MHz IKR002V5D

STMicroelectronics IKR002V5D Low Data Rate Transceiver Daughterboard is engineered to support RF wireless applications operating within the sub 1 GHz frequency band. This communication and wireless development tool features the SPIRIT1 low power RF transceiver module finely tuned to 915 MHz, enabling efficient and reliable wireless data transmission.

The daughterboard supports various modulation schemes including 2-FSK, GFSK, MSK, GMSK, OOK, and ASK, allowing flexible integration with different RF system requirements. Its programmable air data rate ranges from 1 to 500 kbps, accommodating diverse data throughput needs while optimizing power consumption.

Designed with very low power consumption in mind, it draws only 9.8 mA during reception and 20 mA during transmission at a power output of +11 dBm, making it suitable for battery-powered or low-power IoT applications. The receiver sensitivity reaches down to -108 dBm, ensuring excellent signal reception even in challenging RF environments.

The device is interfaced via SPI, enabling seamless microcontroller control and integration within embedded systems. It features advanced communications management with automatic acknowledgment, retransmission, and timeout protocol engine, enhancing data integrity and wireless link reliability. Security is reinforced by an AES 128-bit encryption co-processor, protecting data transmissions from interception.

Compliance with RoHS standards underscores product safety and environmental responsibility. Made in Italy, the daughterboard presents a robust solution for developers working on RF wireless communication projects, IoT devices, sensor networks, and embedded wireless systems.
