PT2399 Echo IC Breakout Board
The PT2399 is a low-fi echo IC with built in ADC, Ram, and DAC.
It uses a handful of external resistors and capacitors for filtering and wet/dry mix control.
Breadboarding the circuit can be awkward with so many components so this PCB contains the datasheet reference design along with some enhancements, such as the anti-latch up power on delay transistor circuit on pin 6.
Header pins are used to provide power, audio in/out, and some other optional control interfacing. It is intended to be used for prototyping and integrating with other circuits in an experimental environment.
