STMicroelectronics STEVAL-IKR002V1

Overview

STEVAL-IKR002V1 from STMicroelectronics is a dual-node Sub-GHz RF development kit built around two SPIRIT1 transceivers (169 MHz ISM band) and two STM32L ultra-low-power microcontroller motherboards. It supports 2-FSK/GFSK/MSK/GMSK/OOK/ASK modulation, 1–500 kbps air data rates, -120 dBm receiver sensitivity, 9 mA RX / 21 mA TX current, and integrated AES-128 encryption.

For engineers reviewing the STEVAL-IKR002V1 datasheet, STEVAL-IKR002V1 pinout, STEVAL-IKR002V1 application, or STEVAL-IKR002V1 equivalent, this kit enables rapid prototyping of secure, low-power wireless sensor networks in industrial monitoring, smart metering, and building automation where sub-GHz propagation and battery longevity are critical.

Technical Context

The kit implements a complete point-to-point or star-network wireless development platform: each node integrates SPIRIT1's embedded packet engine with automatic ACK/retransmission/timeout handling and AES-128 hardware encryption, tightly coupled to the STM32L's low-power runtime and USB/JTAG debug infrastructure.

Both daughterboards are factory-tuned for the 169 MHz ISM band with matching RF front-end components; the motherboards provide regulated 3.3 V supply, USB-to-serial bridge, and SPI interface routing between STM32L and SPIRIT1-enabling full firmware control of modulation type, data rate, output power, and packet structure.

FAQ

Does STEVAL-IKR002V1 support over-the-air firmware updates?

Yes. Each motherboard includes USB connectivity and preloaded STM32L firmware that enables bidirectional OTA updates via the PC-based GUI. The SPIRIT1 transceiver handles packetized firmware segments with automatic acknowledgment and retransmission, ensuring reliable delivery even in lossy RF conditions.

Can the 169 MHz daughterboards be used independently of the STM32L motherboards?

No. The daughterboards lack onboard voltage regulation, clock source, or host interface circuitry. They are designed exclusively as SPIRIT1 carrier modules requiring the STM32L motherboard for power, SPI control, GPIO signaling, and USB bridging - no standalone operation is supported or documented.

What software tools are included with STEVAL-IKR002V1?

The kit ships with the SPIRIT1 Software Development Kit containing GUI configuration tool, STM32L firmware examples (Keil/IAR/TrueSTUDIO), driver libraries, AN3974 application note, and packet-engine API documentation - all accessible via ST's official website under product page STEVAL-IKR002V1.

Is FCC/CE regulatory certification pre-applied to this kit?

No. STEVAL-IKR002V1 is a development tool intended for lab evaluation only. While its 169 MHz RF design complies with ETSI EN 300 220-1 V2.4.1 (2012-05) limits, final end-product certification requires integration into a fully shielded enclosure and full-system testing per applicable regional regulations.
