JayShoe based in Philadelphia has created an affordable high quality audio DAC and ADC for use in designing professional quality audio systems using the Teensy 4 and Teensy 4.1. Early bird pledges ...

It’s the Teensy LC – Low Cost ... On board are 13 analog inputs, 8 PWM outputs, on 12-bit DAC output, three serial ports, two SPI ports, and two I2C ports. Most of the pins can drive 5mA ...

For just this problem, [little-scale] has built a MIDI-controllable DAC for generating control voltages. It’s a simple enough build – a Teensy 2 is used to speak USB MIDI to a laptop.
