Product details

Overview

STEVAL-IKR002V2D from STMicroelectronics is an evaluation board for the SPIRIT1 sub-1GHz low-power RF transceiver IC (SPIRIT1QTR), designed to accelerate development of wireless sensor networks and AMR systems. It supports 150–174 MHz, 300–348 MHz, 387–470 MHz, and 779–956 MHz bands; offers 2-FSK/GFSK/MSK/OOK/ASK modulation; delivers -118 dBm receiver sensitivity and +16 dBm programmable output power; and features AES-128 encryption, antenna diversity, and embedded CSMA/CA protocol engine.

For engineers reviewing the STEVAL-IKR002V2D datasheet, STEVAL-IKR002V2D pinout, STEVAL-IKR002V2D application, or STEVAL-IKR002V2D equivalent, this board enables rapid validation of SPIRIT1's low-power RX/TX performance (9 mA RX, 21 mA TX at +11 dBm), dynamic packet handling (96-byte FIFOs), frequency offset compensation, and regulatory compliance with EN 300 220, FCC Part 15, and ARIB STD-T67/T93/T108.

Technical Context

The STEVAL-IKR002V2D implements a complete reference design for the SPIRIT1QTR transceiver in QFN20 package, integrating matching network components, crystal oscillator (26 MHz), RF switch, and antenna interface for 868/915 MHz operation. It exposes all SPI control lines (CSn, SCLK, SDI, SDO), GPIOs (GPO_1–4), IRQ, and analog sensor inputs (battery monitor, temperature sensor) to host MCU.

Board-level architecture supports three operating modes: standard RX/TX, Tx boost mode (enhanced PA drive), and SMPS OFF mode (ultra-low-power sleep). It leverages SPIRIT1's integrated ultra-low-power RC oscillator for wake-up timing and includes hardware support for automatic acknowledgment, retransmission, CRC/FEC, and sync word detection per packet.

FAQ

What microcontroller interfaces are supported on the STEVAL-IKR002V2D?

The board uses a standard 4-wire SPI interface (CSn, SCLK, SDI, SDO) for full register and FIFO access to the SPIRIT1QTR transceiver, plus four configurable GPIO pins (GPO_1–4), one dedicated IRQ output, and analog inputs for battery voltage and temperature sensing - all compatible with STM32, ESP32, and other 3.3 V logic MCUs without level-shifting.

Does the STEVAL-IKR002V2D support antenna diversity?

Yes - the board implements hardware-level antenna diversity using the SPIRIT1QTR's integrated antenna switching algorithm, with two SMA connectors (ANT1 and ANT2) and automatic RF path selection based on real-time RSSI and PQI metrics, improving link reliability in multipath environments like smart meter installations.

Can the STEVAL-IKR002V2D be used for FCC or CE certification testing?

Yes - the board is pre-aligned to meet radiated emission and spurious response limits per FCC Part 15.247/15.249 and EN 300 220-1/-2. Its layout, matching network, and component selection are identical to those used in ST's certified reference designs, enabling direct reuse of test reports for end-product certification when used with approved host firmware.

Is source code or firmware provided with the evaluation kit?

Yes - ST provides the SPIDriver library, SPIRIT1 firmware examples (including point-to-point, star-network, and M-Bus-compliant stacks), and STM32CubeMX-compatible projects via ST's official GitHub repository and X-CUBE-SPIRIT1 software package, covering initialization, packet transmission/reception, AES encryption, and low-power mode sequencing.
