It restores the traditional Raspberry Pi GPIO layout, letting you attach HATs, expansion boards, and other 3.3‑V peripherals without awkward cabling. Ideal for prototyping and permanent projects that need reliable pin access.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompatible Device\u003c\/td\u003e\n\u003ctd\u003eRaspberry Pi 400\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Connector\u003c\/td\u003e\n\u003ctd\u003e40-pin female header (plugs into Pi 400 GPIO)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Connector\u003c\/td\u003e\n\u003ctd\u003e40-pin male header (standard Pi pinout)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePin Pitch\u003c\/td\u003e\n\u003ctd\u003e2.54 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3 V (GPIO logic level)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBoard Dimensions\u003c\/td\u003e\n\u003ctd\u003eApprox. 65 mm x 30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eAttach a sensor HAT (e.g., Sense HAT, Enviro+) to your Pi 400 for environmental monitoring.\u003c\/li\u003e\n  \u003cli\u003eConnect a motor driver HAT and build a small robot or camera slider.\u003c\/li\u003e\n  \u003cli\u003eUse an LCD display HAT to create a compact info dashboard.\u003c\/li\u003e\n  \u003cli\u003ePair with a T-cobbler and breadboard for quick prototyping with LEDs, buttons, and sensors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned exclusively for the Raspberry Pi 400, this adapter uses the standard 40-pin GPIO layout found on Raspberry Pi 3 and 4 boards. Most HATs and add-ons that work with those models will function correctly. The board operates at 3.3 V logic; do not connect 5 V peripherals directly to the GPIO pins without level shifting.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eSimply press the adapter onto the Pi 400’s GPIO block—no soldering or extra wiring is required. The adapter is keyed by the Pi 400’s connector shape, but double-check that pin 1 aligns with the red stripe on the adapter. For external connections, use the male header on top, which mirrors the standard Raspberry Pi pinout.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with standard Raspberry Pi HATs?\u003c\/summary\u003e\u003cp\u003eYes, the adapter faithfully maps the Pi 400’s GPIO pins to the standard Raspberry Pi 40-pin layout. Most HATs designed for Pi 3B+\/4 will work without modification.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it require any soldering?\u003c\/summary\u003e\u003cp\u003eNo soldering is needed. The adapter uses pre‑soldered female and male headers—just press it onto the Pi 400’s GPIO connector.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this with a breadboard?\u003c\/summary\u003e\u003cp\u003eThe male header on top can accept a 40-pin ribbon cable connected to a T-cobbler, which then breaks out to a breadboard. Direct breadboard insertion is not possible due to the dual-row layout.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
