About this item

The EDATEC 40-pin I/O Protector for Raspberry Pi 400 is a vital accessory designed to safeguard your Pi 400 when connecting daughter boards via the GPIO header. It features integrated ESD protection to shield against electrostatic discharge, current-limiting resistors on all GPIO signals, and overcurrent protection that limits current to 2A at 5V and 1.5A at 3.3V, preventing damage and ensuring stable operation. The protector includes two 220µF capacitors for power supply stabilization and a small switch that enables hot-swapping of daughter boards without shutting down the Pi 400. Visual LED indicators provide real-time status of the daughter board’s power, with blinking LEDs warning of excessive current draw. The device comes with a 40-pin ribbon cable, available in rainbow or gray, featuring anti-reverse connectors for easy and secure installation. RoHS compliant and built for durability, this protector is ideal for enhancing the longevity and reliability of projects in robotics, IoT, and custom electronics using the Raspberry Pi 400.
