The Hobby Components Raspberry Pi Prototyping Hat is a versatile prototyping PCB designed for use with Raspberry Pi models 2, 3, 4, and 5.
Key Features:
- Connection: The board connects to the Raspberry Pi's GPIO header using a supplied 40-way IDC header. The GPIO pins are accessible through separate pads, allowing easy connections to the prototyping area.
- Power Supply: The board features dedicated power rails for the Pi’s GND, 3.3V, and 5V pins. These can be conveniently jumpered to the prototyping area.
- Prototyping Area: The main area includes a standard prototyping layout with custom power rails. These rails can be used for routing signals or can be jumpered to the existing GND, 3.3V, or 5V rails. There is a grid of 1mm through-holes which link the top of the board to the bottom track area. These are laid out in a standard 0.1”/2.54mm pitch.
- I2C Header: An I2C header is provided for easy connection of external I2C or mLink devices.
- Mounting Kit: The kit comes with nylon standoffs and screws to secure the board to the Raspberry Pi.
Note: The 40-way IDC and IC headers are supplied unsoldered.
Always test your circuits before connecting the board to the Raspberry Pi as incorrect connections or shorts can irreparably damage your Pi.
Specification:
Product code: HCPROT0103 Dimensions: 65mm x 56mm Prototyping area: ~48mm x ~43mm Prototyping hole pitch: 0.1” (2.54mm) Prototyping hole size: 1mm Raspberry Pi header: 2x20 Way IDC female Kit includes: PCB, 1 x 4way IDC socket, 1x 4 way I2C/mLink header, 8x M2.5 nylon screws, 4 x 11mm M2.5 nylon standoffs
Build Guide:
Step 1: Solder the 4-Pin Header (If Required)
- Insert the 4-pin right-angled header through the I2C/mLink pads on the PCB.
- Solder it to the underside of the PCB.
Step 2: Install the 40-Way IDC Header
- Insert the 40-way IDC header through the pads from the underside of the PCB, so the connector remains on the underside and the pins stick out of the upper side.
- Tip: Solder two opposite pins first. Then flip the PCB to check if the socket is flat against the PCB.
If the socket isn’t flush, reheat each pad one at a time and gently press the socket against the PCB while the solder is melted. - Once the connector is properly seated, solder the remaining pins.
- Finally, use snips or side cutters to trim off any excess pin lengths.
Step 3: Attach the Standoffs
- Position one of the four standoffs on the underside of the PCB, aligning it with a 2.5mm corner hole.
- From the upper side, secure it with one of the supplied screws. Repeat the above for the remaining three standoffs.
Step 4: Attach the PCB to the Raspberry Pi
- Place the prototyping PCB on top of your Raspberry Pi and align the standoffs with the Pi's four mounting holes.
- Use the remaining screws to secure the PCB to the Raspberry Pi from the underside of the Pi.
Important: Always remove the prototyping PCB from the Raspberry Pi before soldering new components to it.
