Teensy 4.x Audio Adaptor (Rev D2)

Notify me when this product is available:

This audio adaptor lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects.

In January 2023, Rev D2 was created due to shortages on the 32 bit version of SGTL5000 and the original SD socket. Rev D2 is functionally the same as Rev D, except the the I2C address selection pads. The I2C address is not configurable on the 20 pin SGTL5000 chip.
