Hello KiCAD community,
I am an occasional user of KiCAD and I am about to start a new PCB project centered around the Teensy 4.1 development board. In my design, the Teensy 4.1 will be mounted as a daughterboard onto my main PCB using two 24-pin single-row receptacles like these: https://www.mouser.fr/ProductDetail/571-6-534237-3.
I see two potential methods to integrate the Teensy 4.1 into my schematic and PCB layout, but each has its own set of issues:
Method 1: Using Receptacle Connectors
- Schematic Editor: Use two 24-pin receptacle connectors (and a line).
- PCB Editor: Assign the corresponding footprint to these connectors.
Issues:
- In the schematic, the pin numbering of the connectors is a simple 1 to 24 sequence. This does not match the Teensy 4.1 pinout, and I don’t have the pin names directly, which increases the risk of errors when designing my schematic.
- In the 3D view of the board, I will only see the receptacles, not the Teensy 4.1 connected to them.
Method 2: Using Teensy 4.1 Symbol and Footprint
- Schematic Editor: Use the Teensy 4.1 symbol.
- PCB Editor: Assign the Teensy 4.1 footprint
Both are available here: ECAD · TeensyUser/doc Wiki · GitHub.
Issues:
- In the BOM, the receptacle connectors are not listed, which is problematic for production.
- In the 3D view, the Teensy 4.1 appears directly on the PCB without the receptacles.
What is the best strategy to adopt? Do you have any advice or alternative methods that could resolve the issues encountered in either approach?
Thank you in advance for your help!
Best regards,
Math
