It compares the boards with retail Pi 4s, discusses their different DRAM packages, and reports boot, clock-speed, kernel-panic, and benchmarking observations. ### Source excerpt The 'Special Value' Pi 4 pictured above is probably the rarest Raspberry Pi I own--even rarer than my blue special edition Pi. A Raspberry Pi reseller briefly listed a special 'value edition' Pi 4. But the product page 404's now. While it was up, my curiosity got the better of me, and now I have two 'value' Pi 4s. What makes them a 'value'? They're only certified to run at 1.25 GHz (retail Pi 4s run at 1.8 GHz, and can usually be overclocked). ## Why the Raspberry Pi Zero 2W May Be the Best Choice for Many Projects DevFeed: [Why the Raspberry Pi Zero 2W May Be the Best Choice for Many Projects]() Original publisher: [Read original article]() Author: Patrick Fromaget Published: 2026-06-29T06:52:12Z Content type: opinion Language: en Sources: [RaspberryTips]() Topics: [Raspberry Pi](), [Server]() Tags: [cpu](), [desktop](), [docker](), [hdmi](), [home-server](), [jellyfin](), [pi-4](), [quick-tips](), [raspberry-pi](), [raspberry-pi-5](), [usb](), [vpn]() ### AI overview The article recommends the Raspberry Pi Zero 2W as a cost-effective choice for many projects, citing its $15 price, quad-core 1 GHz CPU, 512 MB of RAM, Wi-Fi, and Bluetooth.

The board uses a u-blox M8 timing receiver, provides raw GNSS and correlator data, and offers a stable clock signal. The review also covers antenna performance, Raspberry Pi 4 configuration, UART communication, and baud-rate considerations. ### Source excerpt Hi everyone, Disclaimer: this is a review of a free sample I got sent by Uputronics. I recently spotted on Twitter that Uputronics had launched a GPS/RTS Raspberry Pi Expansion Board, and that they were looking for worthy projects to test it. I thought our Galileo/GPS/BeiDou/GLONASS monitoring project galmon.eu might be worthy and Uputronics agreed. Relevant for our purposes, this is an actual 'timing receiver'. Any GNSS chip will get you a location, but some of them go the extra mile to also deliver a very stable clock signal.
