From debug headers to "Swapperoo" resistors and heartbeat indicator LEDs, we're covering it all. Tune in as we share insights, anecdotes, and maybe a few confessions from our own prototyping adventures. Plus, we dive into the importance of making your prototype testing-friendly and discuss a poll that could solve a common UART connection dilemma. This is episode 426 – your prototype's new best friend!
Discussion Highlights:
Debug Headers: Taking inspiration from James Lewis’s Apple Mega 2 project, we discuss the importance of embedding debug headers directly onto the PCB. We also highlight the Tag Connect's footprint as a space-saving, connector-free debugging interface. Test Pads for Production Testing: Crucial for measuring signals ensuring that potential circuit issues are not overlooked. This measure is crucial for validating the prototype’s performance. Jumper Headers in Series on Power Rails: This method allows for the quick disconnection of subsystems for individual testing, enhancing the diagnostic process without the need for circuit alterations.Easy ways to hook up test equipment: By integrating connectors and test points specifically designed for easy attachment of debugging and testing tools, such as multimeters or oscilloscopes, engineers can streamline the troubleshooting process. Signal Integrity Testing Points: To monitor and adjust signal quality proactively, supporting the prototype’s overall integrity.Thermal Management: Managing component temperatures is a critical aspect often overlooked in the early stages of prototyping. The discussion includes practical strategies for thermal management, even in challenging environments like aerospace.Prioritizing Function Over Form: Make the prototype whatever shape it needs to be to be accessible for testing and debugging, even if it means starting with a larger form factor.Early Inclusion of Fiducials and Mounting Holes: The significance of adding fiducials and mechanical mounting holes at the onset of the design process aids in component placement, assembly, and effective heat dissipation.Adding Pass-Through Holes: For unforeseen modifications or component additions post-design, showcasing the flexibility this can provide to a prototype.Poll Discussion: When connecting two chips, each with their own TX and RX lines, should TX be connected to TX, or does TX connect to RX?Relevant links:
