Product details

Overview

STEVAL-IKR002V4 from STMicroelectronics is a dual-node wireless M-BUS development kit comprising two SPIRIT1 868 MHz sub-GHz transceiver daughterboards and two STM32L-based motherboards with USB interface, JTAG debug connector, and GUI-enabled firmware. It supports 2-FSK/GFSK/MSK/GMSK/OOK/ASK modulation, 1–500 kbps air data rate, −120 dBm receiver sensitivity, 9 mA RX / 21 mA TX current, and AES-128 encryption.

For engineers reviewing the STEVAL-IKR002V4 datasheet, STEVAL-IKR002V4 pinout, STEVAL-IKR002V4 application, or STEVAL-IKR002V4 equivalent, this kit enables rapid prototyping of low-power, secure, ISM-band metering systems compliant with EN 13757-4 wireless M-BUS physical and link layers.

Technical Context

The kit implements a complete dual-node wireless M-BUS system: each node integrates SPIRIT1 (SPI-controlled transceiver) paired with STM32L (ARM Cortex-M0+ MCU) for protocol stack execution, AES encryption offload, and low-duty-cycle RX/TX scheduling. The USB interface bridges PC-hosted GUI to both nodes for real-time parameter configuration and packet monitoring.

SPIRIT1 handles RF baseband processing-including automatic packet acknowledgment, retransmission, timeout management, and flexible preamble/sync word detection-while STM32L manages MAC-layer logic, secure key handling, and host communication via SPI and USB CDC class.

Key Specifications

Parameter	Value and Actual Design Meaning
Air Data Rate	1–500 kbps: supports narrowband utility metering (e.g., 2.4–100 kbps EN 13757-4 modes) and higher-rate sensor telemetry.
Receiver Sensitivity	−120 dBm @ 1.2 kbps: enables reliable reception at >1 km range in urban environments with minimal infrastructure.
TX Output Power	+11 dBm max: meets ETSI EN 300 220-1 Class 1A spectral mask and ERP limits for 868 MHz ISM band.
Supply Current	9 mA RX / 21 mA TX: allows battery operation >10 years in typical gas/water meter sleep-awake duty cycles.
Modulation Schemes	2-FSK, GFSK, MSK, GMSK, OOK, ASK: ensures interoperability with legacy and next-gen M-BUS endpoints and repeaters.
Security Engine	AES-128 co-processor: hardware-accelerated encryption/decryption for secure payload transport per M-BUS security profiles.

Availability

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, analog ICs, power devices, and sensors for industrial, automotive, and consumer applications.

This kit belongs to ST's STEVAL evaluation platform family, engineered to accelerate time-to-prototype for sub-GHz IoT and utility infrastructure systems using SPIRIT1 and ultra-low-power STM32L MCUs.

FAQ

Does STEVAL-IKR002V4 support over-the-air firmware updates?

Yes. Each STM32L motherboard includes USB DFU (Device Firmware Upgrade) capability, enabling field firmware updates without JTAG hardware. The provided GUI supports drag-and-drop binary loading and version verification via CRC-32 checksum.

Can the kit operate in point-to-multipoint topology?

Yes. SPIRIT1 supports configurable node addressing and broadcast/multicast packet filtering. The included firmware implements master-slave roles, allowing one node to act as concentrator polling up to 255 endpoints using configurable channel hopping and ACK retry policies.

Is antenna matching pre-tuned for 868 MHz operation?

Yes. Each SPIRIT1 daughterboard integrates a 50 Ω RF front-end with integrated balun and matching network optimized for 868.0–868.6 MHz, validated with −120 dBm sensitivity and <−60 dBc spurious emissions per ETSI EN 300 220-1.

What software tools are included with the kit?

The kit ships with SPIRIT1 SDK v2.3.0, STM32L firmware source (IAR EWARM & GCC compatible), Windows GUI for packet injection/analysis, and documentation including AN4251 (M-BUS implementation guide) and UM1721 (firmware API reference).
