Hardware Platforms and Development Boards Questions

Knowledge of microcontroller and development board ecosystems used for embedded projects. Candidates should be able to describe experience with families of controllers such as ARM Cortex M series and commonly used vendor lines, selecting appropriate development boards such as Arduino or vendor system on modules, and the trade offs between different platforms with respect to memory, peripherals, power, and cost. This includes familiarity with cross compilation toolchains and board support packages, flashing and boot procedures, bring up workflows, debugging interfaces and adapters, vendor SDKs and drivers, and practical concerns such as pin multiplexing and power rails. Interviewers may probe ability to choose a board for a particular constraint set and to explain environment setup and validation steps.
