Engineering Tradeoffs — question 6 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
You're picking a microcontroller for a project. Option A costs $2 and has just enough flash and RAM to fit the current firmware with zero margin. Option B costs $5, has double the flash and RAM, and is pin-compatible with Option A. You're about to order 50 boards for a semester-long project that has two more feature additions already planned. Which do you choose, and walk me through the reasoning, including any numbers you'd use to decide.
