I have a Teensy4.1 and audio board. My intention is to try the impressive SDR project which is described in a thread on this forum.
My problem, is how best to stack or connect the Teensy and audio board, while still allowing easy connection to all other (unused) pins.
Now I have a previous project in which I used a Teensy3.1 and audio board. I plugged them both into a breadboard and had jumper wires for all necessary audio connections. When I tried playing back a MP3/WAV there was bad distortion. The only way to get the pair to work without distortion was to stack them vertically. Also to get access to the pins not used by the audio board, I resorted to soldering wires directly to the top pins of the Teensy, but it looks horrible.
Now I normally use the double pins in my Teensy so that the board can be plugged into a solderless breadboard. I would like to be able to plug the Teensy4.1 into a breadboard (without the audio board), but I would also like to be able to connect or stack the Teensy4.1 and audio board, while still allowing access for jumper wires to the unused pins on the audio board and the extra pins (not connected to the audio board) of the Teensy4.1.
One idea is to use the Arduino connectors, as they have long pins on the bottom to plug into the breadboard, but allow other pins to be plugged into the top part of the connector.
I considered using the above type connectors for both the Teensy4.1 (which would be on the bottom) and the audio board (on the top).
Any other ideas?
