The Zeenko near-field probe set based on a 4-layer PCB enables precise detection of EMI sources in electronic circuits. When used with spectrum analyzers such as tinySA ULTRA, it provides effective electromagnetic diagnostics without the need for external amplifiers. An ideal solution for analyzing and eliminating interference in electronic systems.

A passive infrared motion sensor designed for Tiny FX projects and interactive installations. It detects motion within a 3-5m range and generates a simple 3.3V digital signal, ideal for triggering lighting effects and animations. Adjustable sensitivity, a wide viewing angle, and very low current draw make it ideal for battery-powered projects. The module is completely ready to use and can be connected without soldering using a JST-SH connector. Pimoroni PIM749
