Teensy 4.0 shield with ADC, DAC and breakouts for perfboard

The PCB can be ordered at a PCB manufacturer of your choice. I ordered mine at Aisler.

The headers on the teensy need to be on the same side as the USB port, so that the USB port faces towards the PCB when mounted. This is done to allow utilisation of the backside pins of the Teensy. There are also 5V and GND markings on the PCB to ensure correct orientation.
