Solutions & Use Cases

Pre-configured FirmwareMaestro project recipes (MCU + use case combinations) and the open-ended use case templates they are built from.

Solutions are opinionated starter recipes — each one pairs a specific MCU with a specific use case and explains why that combination works. Use Cases are the generic templates behind those recipes; pick one if you know what you want to build but not which chip to target.

Solution Recipes

Each recipe targets a single MCU and a single project type, with rationale, key protocols, and the 12 documents FirmwareMaestro generates for it.
