产品详情

The AD-M2KCOMPEDU-EBZ is an education-focused companion board for ADALM2000-based teaching labs, demonstrations, and student projects. It brings together stimulus generation, measurement access, biasing, user controls, sensing, and communication functions in a compact USB-powered board. This helps instructors and students move from basic circuit measurements to complete mixed-signal experiments with fewer external modules.

The board is intended to complement ADALM2000 and other standard laboratory equipment. It provides analog input and output access, digital output functions, power supplies, sensors, controls, LEDs, display connectivity, a transceiver interface, adjustable voltage references, and current-source functions. Arduino UNO R4 support adds a programmable control layer for menu-driven operation, calibration routines, signal-generator control, and embedded-system exercises.

System Features:

  • USB-C input power with 900mA onboard current limit
  • ADALM2000 plug-in option
  • Arduino UNO R4 plug-in option
  • ±12V onboard power supply generators with foldback current limit
  • Selectable +3.3V supply source: Arduino +3.3V rail or onboard local LDO
  • Two adjustable DC reference voltage generators, buffered, and output-current limited
  • Adjustable DC current-source function
  • Audio amplifier path for signal-conditioning and audio experiments
  • Onboard temperature and optical sensing, user potentiometers, switches, buttons, LEDs, and display support
  • CAN transceiver support for communication and control exercises
  • Software-controlled signal generator and calibration flow

APPLICATIONS

  • Classroom electronics laboratories
  • ADALM2000-based teaching and demonstrations
  • Mixed-signal signal-chain demonstrations
  • Student projects and prototyping
  • Embedded control and communication exercises
  • University, technical faculty, and maker/hobbyist learning environments
