Arduino ☛ Analog gauge array helps evaluate compilation efficiency
The device contains an Arduino Mega 2560 board and it receives utilization data through serial from a PC running a custom Rust program. That program uses some resources, but it is trivial compared to everything else. The Arduino employs pulse-width modulation (PWM) to control the positions of the gauge needles. There is also a strip of WS2812B individually addressable RGB LEDs illuminating the gauges, with the colors corresponding to utilization. So high utilization will move a gauge’s needle to the right and cause it to light up red.

Hackster ☛ Eben Upton Hints at an RP2040 Successor, Promises a Raspberry Pi Compute Module 5 in 2024
Raspberry Pi's Eben Upton has hinted that a successor to the company's wildly popular RP2040 dual-core microcontroller may be on the way — and that the Raspberry Pi Compute Module 5 will launch in 2024, with "a high degree of commonality" with the earlier Compute Module 4.

[Old] Hackster ☛ Raspberry Pi 5 Review — Hands-On with the Most Powerful Raspberry Pi Yet
The Raspberry Pi 5 is at once more of the same and something entirely new. It mimics the footprint of its predecessors near-perfectly, and runs the same software — but it delivers a headline-grabbing claim of three times the performance and, for the first time in a mainstream Raspberry Pi model, high-speed PCI Express connectivity to external hardware.
