Pi Cap + Raspberry Pi Guide

Use this guide to decide which Raspberry Pi to use

pi cap with pis

The Pi Cap is a great add-on for any Raspberry Pi that has a 40 GPIO pins connections. Within the Pi family, there are multiple models, but the two latest, most distinguishable ones are the Raspberry Pi 4 Model B and the Raspberry Pi Zero W. In this tutorial, we’ll quickly explain which of the two Raspberry Pis is better suited for your Pi Cap project. You can find more information about all the Raspberry Pis on the Raspberry Pi foundation website.

Raspberry Pi 4

The Raspberry Pi 4 is the powerhouse of the two, which allows you to use the Pi Cap, run multiple programmes and a screen altogether. If you need processing power, an ethernet cable connection or WiFi with your Pi Cap, we’d recommend a Raspberry Pi 4.

Because of the form of the Raspberry Pi 4, the Pi Cap sits on top of the device and it can be cumbersome to cold solder to the Raspberry Pi 4. The Pi 4 requires more power, and is therefore not ideal for any battery-powered Pi projects.

The Raspberry Pi 4 Model B tends to get hot, so if you are working on projects, where you need to be wary of the temperature, you might want to check out a previous version of the Raspberry Pi, like Raspberry Pi 3, or use a heat sink.

Raspberry Pi Zero

The Raspberry Pi Zero W is smaller than the Raspberry Pi 4, which makes it easier to neatly integrate your Pi Cap with your Pi into your project. If you want to cold solder to the Pi Cap, then we’d recommend this Pi. The Raspberry Pi Zero W is ideal for small projects without a need for video or lots of USB accessories, so for example, if you just want to gather data with your Pi Cap and send it wirelessly, we’d recommend the Raspberry Pi Zero.
