STMicroelectronics STEVAL-ILL015V2

Overview

STEVAL-ILL015V2 from STMicroelectronics is an evaluation board for the LED2472G 24-bit constant-current RGB LED sink driver and STM32F103Cx microcontroller, configured with two TQFP48 LED2472G ICs driving three 16-LED RGB strings (48 total LEDs), featuring diagnostics, overtemperature/short/open fault detection, and a ST1S10 DC-DC converter (7.5–18 V input, 0.7 A).

For engineers reviewing the STEVAL-ILL015V2 datasheet, STEVAL-ILL015V2 pinout, STEVAL-ILL015V2 application, or STEVAL-ILL015V2 equivalent, this board supports rapid validation of high-brightness LED panel control, real-time fault simulation via 6 jumpers (3 open/3 short), JTAG firmware updates, and PC GUI integration via Mini USB.

Technical Context

The board implements a dual-LED2472G architecture with independent R/G/B output enable lines per driver, enabling per-channel current control and error flagging. Each LED2472G provides 24 constant-current sinks (8 per color) with ISET-adjustable current up to 50 mA per channel and integrated open-circuit/short-circuit detection logic.

The STM32F103Cx MCU handles serial data framing, diagnostic aggregation, and user interface (knob/buttons), while the ST1S10 synchronous buck regulator delivers stable 3.3 V at up to 1.5 A and 4.5 V at up to 1 A for logic and LED bias rails - both with thermal shutdown and current limiting.

FAQ

What is the primary function of the STEVAL-ILL015V2 evaluation board?

The STEVAL-ILL015V2 is a complete hardware platform for evaluating ST's LED2472G constant-current RGB LED driver and its integration with STM32 microcontroller-based diagnostics and control. It enables functional validation of 48-LED RGB arrays, real-time fault injection, and GUI-driven parameter tuning - not a production-ready module.

Does the board support standalone operation without a PC connection?

Yes - the board operates autonomously using its onboard STM32F103Cx MCU. All core functions (LED driving, fault monitoring, button/knob control) work without USB or PC. The Mini USB interface is optional, used only for GUI interaction or firmware updates via JTAG/SWD.

Can the LED2472G current settings be adjusted, and how?

Yes - each LED2472G uses an external ISET resistor (R9/R6 on U1/U2) to set the reference current. With the default 36 kΩ resistors, full-scale sink current is ~35 mA per channel. Adjusting ISET changes all 24 outputs proportionally, enabling precise brightness calibration across RGB channels.

What safety or compliance certifications does the board carry?

The STEVAL-ILL015V2 is RoHS compliant (per documentation) and designed for lab evaluation only - it carries no UL, CE, or IEC safety certification. Its DC input (7.5–18 V) and low-voltage LED outputs (<5 V) limit hazard potential, but it is not rated for end-product regulatory compliance or field deployment.
