About this item

The EDATEC 40-pin I/O Protector for Raspberry Pi 400 with a grey ribbon cable is a crucial accessory designed to protect your Pi 400 when connecting daughter boards via the GPIO header. It offers robust protection against electrostatic discharge (ESD) with an integrated immunity IC, overcurrent protection limiting current to 2A at 5V and 1.5A at 3.3V, and 33Ω resistors on all GPIO signals to prevent damage from short circuits. The protector features two 220µF capacitors that stabilize the 5V and 3.3V power supplies, ensuring consistent voltage levels. A small switch allows independent powering of the daughter board for safe hot-swapping without powering down the Pi 400. LED indicators provide real-time feedback on power status, with blinking LEDs warning of excessive current draw. The device includes a 40-pin grey ribbon cable with anti-reverse 40-pin black male and female connectors for secure and easy installation. RoHS compliant and built for durability, this protector is ideal for enhancing the longevity and reliability of Raspberry Pi 400 projects in robotics, IoT, and custom electronics applications.
