About a month ago, the geek web got a pleasant surprise with the announcement of the Raspberry Pi 4 mini computer, which wasn’t expected to be released until 2020. This version comes with enough upgrades that it can finally be considered a budget PC option, and one that can still fit in your pocket:

This is a comprehensive upgrade, touching almost every element of the platform. For the first time we provide a PC-like level of performance for most users, while retaining the interfacing capabilities and hackability of the classic Raspberry Pi line.

At first glance, the Raspberry Pi 4 board looks very similar to our previous $35 products, all the way back to 2014’s Raspberry Pi 1B+. [James Adams, Director of Hardware] worked hard to keep it this way, but for the first time he has made a small number of essential tweaks to the form factor to accommodate new features.

Here are the spec highlights so you can see the leaps and bounds it’s improved over its predecessor, the Pi 3 Model B+:

• Up to 4GB of RAM
• Full-throughput gigabit ethernet (no more USB throttling!)
• Dual-band 802.11ac Wi-Fi
• Bluetooth 5.0 (up from 4.2)
• Two USB 3.0 and two USB 2.0 ports (up from four 2.0 ports)
