STMicroelectronics EVL6208-PLUG

Overview

EVL6208-PLUG from STMicroelectronics is a plug-in evaluation board designed for the L6208PD dual H-bridge motor driver IC, enabling rapid prototyping of bipolar stepper and dual brushed DC motor control systems. It supports 8–52 V supply voltage, delivers up to 2.8 A r.m.s. phase current, and features programmable PWM OFF-time and half/full-step mode selection via dedicated control pins. The board integrates fault reporting (FAULTA/FAULTB), current sense inputs (SENSEA/SENSEB), and Arduino UNO R3 connector compatibility.

For engineers reviewing the EVL6208-PLUG datasheet, EVL6208-PLUG pinout, EVL6208-PLUG application, or EVL6208-PLUG equivalent, this page provides verified functional context, validated interface mapping to the L6208PD IC, confirmed current-sense and control signal routing, and direct integration guidance with the EVL62XX-MAIN baseboard and STSPIN Studio software.

Technical Context

The EVL6208-PLUG implements the full signal interface between the EVL62XX-MAIN host board and the L6208PD motor driver IC, including dedicated traces for CLOCK, CW/CCW, HALF/FULL, CONTROL, RESET, VREFA, VREFB, RCA, RCB, SENSEA, SENSEB, EN, OUT1A–OUT2B, and fault outputs. All critical power paths (VS, VSA, VSB) and bootstrap circuitry (VBOOT, VCP) are routed per L6208PD layout guidelines.

It provides hardware-configurable options via zero-ohm jumpers (e.g., R1, R2, R3, R4, R7, R9, R11, R12, R13, R15, R19) to match L6208PD's internal architecture - including external RC timing networks for PWM off-time control (RCA/RCB), reference voltage scaling (VREFA/VREFB), and enable/reset logic polarity. No microcontroller or firmware resides on the plug-in board; it functions purely as an analog/digital signal adapter.

FAQ

What motor types does EVL6208-PLUG support?

EVL6208-PLUG supports bipolar stepper motors and dual brushed DC motors when used with the L6208PD driver IC. It enables full four-quadrant control, microstepping via external PWM, and configurable decay modes. Motor connection is via screw terminals A+/A−/B+/B− on the EVL62XX-MAIN baseboard, not directly on the plug-in board.

Is EVL6208-PLUG compatible with STM32 Nucleo boards?

Yes - EVL6208-PLUG is designed for use with the EVL62XX-MAIN baseboard, which features an STM32 Nucleo-compatible footprint and Arduino UNO R3 pinout. It interfaces directly with STM32 GPIOs for CLOCK, CW/CCW, CONTROL, RESET, and FAULT signals, and uses ADC channels for SENSEA/SENSEB feedback.

Does EVL6208-PLUG include onboard firmware or configuration memory?

No - EVL6208-PLUG is a passive hardware adapter board with no microcontroller, flash memory, or firmware. All configuration (e.g., step mode, current limit, decay timing) is set via external resistors, jumpers, and digital control signals from the host MCU. Operation is fully defined by the L6208PD datasheet and STSPIN Studio software.

How is current limiting implemented on EVL6208-PLUG?

Current limiting is implemented through the L6208PD's internal PWM current control loop, configured via VREFA/VREFB reference voltages and external RCA/RCB timing resistors. SENSEA/SENSEB connect to low-value shunt resistors on the EVL62XX-MAIN board, feeding analog feedback to the L6208PD's current comparators - no calibration or software tuning is required for basic operation.
