SideCar is a modern, lightweight, and extensible utility designed to unlock the full potential of auxiliary displays, such as the secondary screens found on devices like the Positivo Vision R15 M.
Unlike generic monitor tools, SideCar is a specialized rendering engine that transforms raw system metrics into beautiful, structured dashboards.
- Modern Dashboard UI: A refined interface with indigo/violet accents, optimized for high legibility and professional aesthetics.
- Native Metrics: "Pure Go" implementation for collecting CPU, RAM, Battery, and Network metrics without external binary dependencies.
- Advanced WiFi Monitoring: Native SSID detection and signal quality monitoring (Linux).
- Power Intelligence: Automatically manages device energy by detecting system sleep and wake events (Cross-platform).
- Responsive Design: Adaptive interface that works perfectly in full screen or compact window modes.
- Lightweight & Portable: Written in Go and JavaScript, designed to be fast and low-impact on system resources.
To communicate with the auxiliary hardware via the serial port, SideCar requires specific system permissions.
On Windows, the serial communication is restricted to administrative processes.
- Requirement: Right-click the
SideCar.exeand select "Run as Administrator".
Linux systems restrict access to /dev/ttyACM* devices by default. You have two ways to grant access:
This is the standard way to grant permanent access to serial ports.
- Run the following command in your terminal:
sudo usermod -a -G dialout $USER - Important: You must log out and log back in for the changes to take effect.
If you just want to test it quickly:
sudo chmod 666 /dev/ttyACM0(Replace ttyACM0 with your actual device port if different)
An auxiliary screen should not just be a decorative element; it is a vital information surface. SideCar exists to provide a bridge between your system's heartbeat and that surface, focusing on security, performance, and clean design.
🚧 Active Development. Features and dashboard layouts are being constantly refined to match professional standards.
