STMicroelectronics STEVAL-ILL002V3

Overview

STEVAL-ILL002V3 from STMicroelectronics is a high-brightness LED demonstration board featuring five STP08DP05 8-channel power logic drivers with output error detection, an ST7FLITE3x 8-bit microcontroller, and a 5×8 blue LED matrix (OSRAM). It supports brightness/blink-speed regulation, animated text display, and GUI-based diagnostics over RS-232.

For engineers reviewing the STEVAL-ILL002V3 datasheet, STEVAL-ILL002V3 pinout, STEVAL-ILL002V3 application, or STEVAL-ILL002V3 equivalent, this board serves as a validated reference for LED matrix control, fault-aware driver evaluation, and embedded GUI-driven lighting system prototyping.

Technical Context

The board implements a complete LED driving solution using five STP08DP05 drivers in parallel, each managing eight outputs with open-load and short-circuit detection via serial SDO feedback. The ST7FLITE3x MCU handles timing, animation sequencing, and RS-232 communication with the host PC GUI.

A DC-DC converter (L5970D) provides regulated 5 V from 7–32 V input; the ST232ABN transceiver enables TTL-to-RS-232 level translation. All 40 LEDs are OSRAM blue devices driven in constant-current mode with per-channel diagnostics accessible without hardware probing.

FAQ

Is STEVAL-ILL002V3 still in production?

No - STEVAL-ILL002V3 is marked obsolete by STMicroelectronics as of the May 2009 data brief. It remains available through authorized distributors for legacy design support and educational use, but no new revisions or long-term supply commitments are offered.

What software tools are required to operate the GUI?

The board uses a Windows-based graphical user interface distributed by ST, compatible with standard COM ports. No additional SDK or compiler is needed - the ST7FLITE3x firmware is preloaded and communicates via ASCII commands over RS-232 at 9600 baud.

Can the LED matrix be reconfigured for different topologies?

Yes - the 5×8 layout is fixed, but jumper JP1 and JP2 allow selection between common-anode or common-cathode drive modes. Individual STP08DP05 channels can be enabled/disabled via MCU firmware, supporting custom scan patterns and partial activation.

Does the board support PWM dimming control?

Yes - brightness regulation is implemented via variable-frequency PWM generated by the ST7FLITE3x, applied to the /LE (latch enable) inputs of the STP08DP05 drivers, allowing smooth intensity control across all 40 LEDs simultaneously.
