Features - Kauai Labs VMX-pi User Manual

Overview
VMX-pi
Switched-mode Power supply for Raspberry Pi and external devices, including under-
voltage management and over-current/short-circuit protection
30 Digital IOs and 4 Analog Inputs including circuit protection against over-voltage, and
locking connectors for many functions
Digital Communication Interfaces including CAN, SPI, I2C and UART
navX-technology 9-axis IMU enabling Motion processing features
including Field-Oriented
and more
Network Time Server w/Battery-backed Real-time clock for synchronizing data and logs
on distributed networked robot controllers
Additional Key Features:
Write code directly on VMX-pi: Functions either as a standalone Development System
(via Raspberry Pi inputs for keyboard, mouse, HDMI monitor), or can be used with a
remote development environment
Easily connect to sensors: Breakout boards are available for easily connecting to the
Sparkfun QWIIC Connect System
Power up with VMX Robotics Toolkit:
VMX Robotics Toolkit (VMX-rtk)
Video Streaming, Vision Processing Libraries, NTP Server, Real-Time Linux (PREEMPT_RT),
ROS Kinetic, WPI Network Tables and more:
Vision processing with multiple cameras via Raspberry Pi-based OpenCV libraries and
USB or Raspberry Pi Camera interfaces
Video streaming and Video capture to SD Card from Raspberry Pi
Robot Localization via Motion/Vision Processing fusion with sensor fusion packages
(e.g., via the ROS
Integration with environment mapping sensors (e.g., stereo cameras & 2D or 3D LIDAR)
to implement Simultaneous Localization and Mapping (SLAM) (e.g., via the ROS
gmapping package)
Raspberry Pi Power Management & Communication
Switched-mode power supply for Raspberry Pi (up to 2.1A, enough to power many USB-
connected devices)
Conforms to
Raspberry Pi 3B and Raspberry Pi Zero/W
High-speed internal communication between VMX-pi realtime IO controller and
Drive, Auto-balance,
Raspberry Pi Software Images add many features including
