## Description

The Raspberry Pi 40-Pin GPIO Double Expansion Board splits your Pi's single GPIO header into two, letting you connect multiple HATs, breakout boards, or accessories simultaneously without stacking conflicts. Simply connect it to your Raspberry Pi's 40-pin header, and you'll have two full GPIO breakouts ready to use. All 40 pins are passed through to both headers, giving you complete access to power, ground, I2C, SPI, UART, and all GPIO pins on each side. Key Features 1-to-2 GPIO Expansion – Duplicates all 40 pins across two headers Full Pin Pass-Through – All GPIO, power, I2C, SPI, and UART pins available on both outputs No Software Required – Plug-and-play hardware solution 40-Pin Compatible – Works with Raspberry Pi models featuring the standard 40-pin header Ideal For Using multiple HATs or breakout boards at the same time Prototyping with breadboard access while a HAT is attached Testing and debugging GPIO connections Package Contents 1× 40-Pin GPIO Double Expansion Board
