DESIGN YOUR CM4 CARRIER WITH WIFI PERFORMANCE IN MIND

The Raspberry Pi Compute Module 4 has a built-in WiFi antenna, but that doesn’t mean it will work well for you – the physical properties of the carrier board impact your signal quality, too. [Avian] decided to do a straightforward test – measuring WiFi RSSI changes and throughput with a few different carrier boards. It appears that …

This tape cassette is actually a full-fledged computer (powered by a Raspberry Pi Zero W)

The Sinclair ZX Spectrum was a compact and affordable personal computer when it first launched in 1982 for £125 (the equivalent of £470 or $745 in 2022). Designed to use tape cassettes for storage, it was also relatively easy to obtain media. But computers have gotten a lot smaller and cheaper over the past four decades, and …

WIRELESS BOOTLOADER SAVES YOU FROM SWAPPING ROM CHIPS

Flashing your code into an Arduino, an ESP32 or any other modern microcontroller platform is pretty straightforward: connect the device through USB, fire up the appropriate software platform, and press “program”. But those who followed embedded programming classes in the ’80s and ’90s will remember a more complicated procedure that consists of swapping EPROM chips …

A POWER BUTTON FOR RASPBERRY PI, COURTESY OF DEVICE TREE OVERLAYS

As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a Raspberry Pi system. Using these DTOs it’s trivial to set up features like as a soft power-off button, triggering an external power supply and enable …
