CrowdSupply recently launched the USB Insight Hub, a tool designed to provide detailed monitoring and control over multiple USB devices. Built for developers and tech enthusiasts, this hub offers a range of monitoring features, allowing users to view power and data usage in depth.
The hub features a Renesas uPD720210 USB 3.0 controller, supporting both USB 2.0 and USB 3.0 standards, ensuring compatibility with a wide range of devices. An ESP32-S2 microcontroller manages display and control functions, while an STM8S003K3 microcontroller extends input and output capabilities.
Each downstream port’s power and energy monitoring is handled by a PAC1943 module, providing accurate current and voltage readings with a resolution of 1 mA and 1 mV. Power control for each port is managed by an AP22653 switch, which offers configurable hardware current protection and software-based overcurrent and reverse current protection.
