Raspberry Pi Zero WH

This version of Raspberry Pi has similar features to Pi Zero W. However, this Raspberry Pi has an added advantage: a pre-soldered General-purpose input/output Pins GPIO header. These are the pins located on an integrated circuit. Conversely, it does not have a specific function assigned to it. The GPIO provides an interface between the Raspberry Pi and other interlinked components. A disadvantage linked with this type of Raspberry Pi is that it is hard to find compared to the regular W.

Raspberry Pi Zero

Pi Zero is one of the cheapest available Raspberry Pi. Therefore, if you have a tight budget and you would like to try out a Raspberry Pi, try the Raspberry Pi Zero. However, this Pi lacks both Bluetooth and wireless fidelity (Wi-Fi). You only have the Ethernet option, or you can purchase a Bluetooth and Wi-Fi dongle if you need to connect online. Additionally, you can share a PC’s connection(internet) via USB to get connected.

Raspberry Pi Zero W

This Raspberry Pi version uses a 1.0 GHz clock speed, which means it has a reduced speed level than Raspberry Pi Zero WH. It has a memory of approximately 512 MB RAM and a single-core CPU. If you have been looking for a lightweight Raspberry Pi, then this version should be your choice. The Pi is around 0.3 ounces which is equivalent to 9grams. Despite the mentioned flaws of this computer, it is reliable when performing tasks such as motor, cameras, or driving lights.

Zero W has wireless fidelity (Wi-Fi) and Bluetooth 4.0, unlike the Zero Pi. When using this Raspberry Pi, you have to buy Pins and a solder since it is not attached to GPIO Pins. Another setback of this Raspberry Pi is that it uses a micro-USB instead of a full-size USB, which means you will need to purchase a USB adapter.

Raspberry Pi 3B+/3B

This Raspberry Pi lacks features such as a USB 3.0 port and dual-monitor support. However, it supports other excellent features such as the standard HDMI cables with recommended 5 volts power levels. This Raspberry Pi emits less heat, thus consuming less power. For those wondering where to find a computer that works significantly well with passive cooling throughout projects, then you need to find yourself a 3B/3B+ Pi.
