New Bela Gem Stereo and Multi Audio Embedded Linux Boards

Bela announced the launch of Bela Gem, a powerful and accessible platform for real-time audio and sensor processing. Available in two versions – Stereo (2-in/2-out) and Multi (10-in/10-out) – Bela Gem transforms the PocketBeagle 2 single-board computer (SBC) into a lightning-fast embedded system for instruments, sound installations, effects units, and more. The two products are available through a Crowd Supply campaign now live, with shipping planned for October 2025.

The first article from audio expert Ethan Winer about Modern PCB Design Practices, gave a general overview of board design using surface-mounted devices (SMDs). The article examines current practices and methods for designing four-layer printed circuit boards using surface mounted components (SMDs), and this second part explains specific strategies and related issues to deal with the design and production of great quality PCBs. This article was originally published in audioXpress, March 2023.

In this two-part series, Ethan Winer examines current practices and methods for designing four-layer printed circuit boards using surface-mounted components (SMDs). A great article for our DIY readers and many developers who often are faced with the need to build and test their projects on a properly designed, prototype printed circuit board. Part 1 presents an overview of the process, while Part 2 he will explain specific strategies. Many related issues will be described along the way.
