Raspberry Pi Proto Hat Shield

Custom Prototyping Grid: Features a grid of plated through-hole prototyping pads, allowing makers and engineers to solder custom circuits, sensors, ICs, and passive components directly onto a HAT form factor.

Standard 40-Pin GPIO Header Integration: Includes a stacking female header that breaks out all 40 GPIO pins, maintaining full signal access for custom hardware projects.

Onboard EEPROM Footprint: Outfitted with dedicated solder pads for an optional I2C EEPROM chip, enabling compliance with official Raspberry Pi HAT specifications for auto-configuration at boot.

Standard HAT Form Factor & Mounting Holes: Precision-engineered to match the official Raspberry Pi HAT mechanical layout with standard corner mounting holes for secure mounting using brass standoffs.

Power & Ground Rails: Designed with clearly labeled bus lines for $+3.3\text{V}$, $+5\text{V}$, and $\text{GND}$ across the prototyping area to simplify component wiring and power distribution.

PCB Composition: Constructed on a high-grade FR4 glass-reinforced epoxy laminate with lead-free surface finish for reliable solder adhesion and heat endurance during assembly.

Soldering & Thermal Limits: Safe for standard hand-soldering irons operating up to $350^\circ\text{C}$. Avoid applying prolonged direct heat to individual pads to prevent trace delamination.

Static Handling Precautions: Practice standard ESD precautions during component assembly and installation to prevent static damage to connected microcontrollers or sensors.

Environmental & Cleaning Limits: Clean residual flux using isopropyl alcohol (IPA) and a soft brush. Keep protected from conductive debris, moisture, and liquids while connected to live power.

Essential Maker & Hardware Tool: Position as a must-have accessory for students, hobbyists, and hardware engineers building permanent custom circuits without custom PCB manufacturing delays.

Breadboard-to-Final Project Bridge: Highlight this board as the ideal transition tool for taking temporary breadboard circuits and turning them into durable, stackable HAT shields.

Recommended Cross-Sell Add-ons: Pair with Solder Kits, 0402/0805 SMD Passive Component Kits, Brass Standoff Sets, and Male/Female Breakable Headers.

Universal Compatibility: Emphasize compatibility across all 40-pin Raspberry Pi models, including the Raspberry Pi 5, 4B, 3B+, and Zero series.
