====== iPod 30pin device simulation ======

There are plenty good receivers and amps with iPod 30pin dock. Of course there are Bluetooth adapters cheaply available, some amps need pe-amplified models. I have not come upon a version that properly supports remote control commands, so let's create our own. Then a replacement PCB for Yamaha R-840 can be created easily. \\

For modification of iPod Dock on Yamaha R840 (with remote control) see: [[:projects:yamaha_r840#ipod-30pin_dock|Yamaha iPod 30pin dock]] \\
If your amp has USB iPod input, see [[projects:yamaha_r840#usb_ipod_iap|USB iAP section of Yamaha page]]. \\

Some older players (e.g. car radios) only provide 12V via firewire lines (pins 19+20) instead of 5V (pin 23). Use an LDO or switching regulator to get desired voltage. Adapt [[projects:usb-c-ify#voltage_regulators|voltage regulator for BMS]] to your needs. \\
