Getting a new embedded platform's toolchain working can be one of the most frustrating parts of development—especially when you just want to start writing code. The JL JieLi AC696N is a popular chip for Bluetooth audio applications, but the initial Windows environment setup has a few quirks. Here's a clean, verified process to get from zero to compile.

Sometimes the best way to understand a new embedded platform is to see what it can do before writing any code. The JL JieLi AC696N development board ships with a factory demo that showcases its complete multimedia capabilities in under five minutes.
Whether you're evaluating the platform for a project or just want a quick hands-on, this is the fastest way to see what the AC696N can do. Next up in this series: adding custom files to the project.
A good pin reference is like a map for hardware development. Here's a verified pin mapping for the JL JieLi AC6966B (AC696N series) development board, straight from actual hardware testing.
Whether you're reviewing schematics, bringing up a custom board, or debugging firmware, having this reference handy saves hours of probing and tracing.

The analog section of a Bluetooth audio SoC is where careful design pays off. Notes from the JieLi AC695N/AC696N guide:
For the DAC outputs, they recommend reserving positions for small inductors (100nH, 120nH, 220nH, 330nH) to form filters that can suppress high-frequency noise, specifically called out as TDD noise from a nearby mobile phone during calls.

For the #electronics and #embedded crowd: a concise summary of the hardware design guide for JieLi AC695N/AC696N Bluetooth audio SoCs.
It offers crucial DFM advice: you MUST provide test points for the programming pins (USB, power), as the small QFN package necessitates programming after SMT assembly via a USB connection.
