Raspberry Pi T type GPIO expansion board

T-Shape Form Factor: Designed in a T-shape layout that plugs directly into a standard solderless breadboard, making pin labels easily readable and leaving ample space for prototyping components on both sides.

40-Pin GPIO Header Extension: Extends and breaks out all 40 GPIO pins from compatible Raspberry Pi mainboards via a standard 40-pin ribbon cable connection.

Clear Pin Labeling: Silkscreened pin labels clearly denote every pin function (GPIO numbers, $+3.3\text{V}$, $+5\text{V}$, $\text{GND}$, $\text{I2C}$, $\text{SPI}$, $\text{UART}$) right on the board surface to prevent wiring errors.

Solderless Breadboard Compatibility: Features dual rows of header pins underneath that plug cleanly into standard breadboard power rails and tie-point rows.

Durable FR4 PCB Construction: Built on a sturdy printed circuit board with gold-plated pins for secure contact and corrosion-free long-term use.

PCB Composition: Constructed on high-grade FR4 glass-reinforced epoxy laminate designed to withstand repeated plugging and unplugging into breadboards.

Pin Alignment Care: Align the underside header pins straight over the breadboard holes before pressing down evenly to avoid bending or snapping pins.

Static Handling Precautions: Standard electrostatic sensitive device (ESD). Hold the board by its outer fiberglass edges and practice standard grounding precautions during setup.

Environmental Limits: Operating temperature range is -20^C to +70^C. Keep protected from liquids, direct condensation, and conductive metallic debris while powered.

Essential Breadboard Prototyping Companion: Position as an indispensable accessory for students, makers, and electronics hobbyists building custom breadboard circuits with LEDs, sensors, and microcontrollers.

Ribbon Cable Bundle Pitch: Cross-sell together with a 40-Pin Rainbow GPIO Ribbon Cable so customers have everything needed to connect their Raspberry Pi out of the box.

Complementary Prototyping Add-ons: Recommend bundling with 830-Point Solderless Breadboards, Jumper Wire Kits, and Basic Electronic Component Kits (resistors, LEDs, buttons).

Universal 40-Pin Pi Compatibility: Highlight full compatibility across all 40-pin Raspberry Pi models, including Raspberry Pi 5, 4B, 3B+, 3B, Zero, and Zero 2 W.
