ATAPI Audio-CD player
Standalone ATAPI/IDE Audio-CD player, based on an Arduino Mega
What is it?
ATAPIMega is a hardware project which allows regular (P)ATA CD/DVD drives to be used as a standalone Audio-CD player.
The PCB accepts (regulated!) 12V DC power via a 5.5mm/2.1mm barrel jack and outputs 12V/5V for the CD drive.
The microcontroller is an ATmega2560 (Arduino Mega-compatible), chosen for 5V-I/O voltage and high pin-count (and bad availability of STM32’s in the component shortage of 2021).
