Product details
Overview
STEVAL-IKR002V3 from STMicroelectronics is a dual-node Sub-GHz transceiver development kit built around two SPIRIT1 RF transceivers (433 MHz band) and two STM32L ultra-low-power microcontroller motherboards. It supports wireless M-Bus systems, offers AES-128 encryption, 2-FSK/GFSK/MSK/GMSK/OOK/ASK modulation, 1–500 kbps air data rate, and achieves –120 dBm receiver sensitivity with 9 mA RX / 21 mA TX current.
For engineers reviewing the STEVAL-IKR002V3 datasheet, STEVAL-IKR002V3 pinout, STEVAL-IKR002V3 application, or STEVAL-IKR002V3 equivalent, this kit enables rapid prototyping of secure, low-power ISM-band wireless metering nodes with GUI-driven configuration, JTAG firmware development, and USB-hosted firmware updates.
Technical Context
The kit implements a complete dual-node wireless M-Bus system architecture: each node integrates SPIRIT1 for sub-GHz RF communication (433 MHz ISM band) and STM32L for protocol handling, AES encryption, and host interface management. The SPIRIT1 provides programmable modulation schemes and automatic packet acknowledgment/retransmission logic.
USB connectivity enables real-time GUI interaction and firmware flashing; JTAG debug support allows full firmware customization on the STM32L. Low-duty-cycle RX/TX operation and deep-sleep modes align with battery-powered utility metering requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Band | 433 MHz ISM band - enables license-free deployment in European utility metering infrastructure. |
| Modulation Schemes | 2-FSK, GFSK, MSK, GMSK, OOK, ASK - supports legacy and modern wireless M-Bus physical layer variants. |
| Air Data Rate | 1–500 kbps - configurable for trade-offs between range, interference resilience, and power consumption. |
| Receiver Sensitivity | –120 dBm @ 1.2 kbps - ensures reliable reception in noisy urban RF environments with minimal transmit power. |
| Supply Current | 9 mA RX / 21 mA TX @ +11 dBm - enables multi-year battery life in periodic-readout metering applications. |
| Security Engine | AES-128 co-processor - hardware-accelerated encryption for secure wireless M-Bus Class C/C1 message protection. |

FAQ
Does STEVAL-IKR002V3 support over-the-air firmware updates?
No - firmware updates require USB connection to a host PC using the provided GUI tool. The kit lacks integrated OTA update capability; all firmware revisions must be loaded via USB interface and STM32L bootloader.
Can the SPIRIT1 transceivers operate outside the 433 MHz band?
No - both daughterboards are factory-tuned for 433 MHz ISM band only. Antenna matching network and RF front-end components are fixed for this band; operation at 868/915 MHz requires different hardware variants (e.g., STEVAL-IKR001V3).
Is JTAG debugging supported on both STM32L motherboards simultaneously?
Yes - each motherboard includes a standard ARM Cortex-M JTAG/SWD connector. Both can be debugged independently using separate debug probes; no shared JTAG daisy-chain or multiplexing is implemented.
What software tools are included with the kit?
The kit ships with SPIRIT1 SDK (including register configurator), STM32L firmware examples, Windows-based GUI for RF parameter tuning and packet monitoring, and full documentation including hardware schematics and layout files.
