A small board to allow a Disk On Module (DOM) to be connected to an IDE cable or Adapter.

This is a hobby project and comes with no official support. The PCB schematic and board design files are offered 'as is' with no claims made about their fitness for any specific purpose.
If you don't know what a DOM is, and you don't use them, then this board is probably not of interest.
DOMs are designed to replace hard disks and are a precursor to the SSDs of today. The DOMs with IDE interfaces are designed to plug directly into the header on a computer motherboard, so if you want to attach one to a cable or use something such as a USB to IDE drive adapter to access a DOM then a 'crossover' adapter is needed; hence this PCB. You can find adapters for sale online, but it was cheaper (my time excluded) to lay out and order a batch from a PCB manufacturer based in the Far East. Plus is was a fun exercise.
Pin 20 on each connector is circled. This pin on the IDE side might need to be removed because this is a keying position and the pin 20 female socket on some IDE cables is blocked off.
If you fancy making your own adapter, you will need a PCB and some PCB header pins. Soldering is obvously required.
