This is a single header version of our 2x GPIO Header Expansion for Raspberry Pi 500/400. Designed specifically to make your hardware projects easier with the Raspberry Pi 500 or Raspberry Pi 400, this GPIO Expansion is a great solution for us keyboardy-computer tinkerers! This expansion has three great features: * It makes access to the Pi 500 GPIO pins MUCH more accessible * It labels and colour-codes the GPIO pins to make pin-finding SO much easier! * It allows you to attach a HAT at a much more convenient and usable angle/position The included standoffs and screws also help to stabilise the board once fitted to your Pi 400 (you may want to add a thin piece of card or similar under these if your desk surface is easily scratched). All you need now is a fancy set of jumper wires and a breadboard! Package Contents * 1x Pi 500/400 GPIO Header Expansion * 1x Fixings pack (standoffs and screws) Raspberry Pi 400/500 not included! https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2023-03-07 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2023-12-27 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2024-09-19 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2024-11-29 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2024-11-30 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2025-08-05 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2025-11-28 https://elecena.pl/product/22720701/gpio-header-expansion-for-raspberry-pi-500-400 2025-11-29
