Wiring Guidelines for Parametric Measurement Units (PMU)

This application note discusses ways to help system designers apply proper layout techniques and signal routing. The layout and component descriptions will minimize noise pick-up and manage the thermal dissipation in applications using PMUs.

syzygy-dual-atto320: SYZYGY to dual Atto320 LWIR sensor

Bluetooth power amplifier board based on TPA3110

Using TPA3110 digital power amplifier chip, the power can reach 15W, and there are two power interfaces. The Bluetooth part uses bk8000L finished module, which has good performance and affordable price. Supports button playback and pause, track switching, volume adjustment, and also supports external audio line input and microphone input. After testing the finished product, the sound quality is good, the Bluetooth connection is relatively stable, the button functions are normal, the external audio line input is normal, and the microphone calls are normal. A complete AD project file is provided, which can be modified as needed, and the BOM needs to be exported by yourself.
