The 501 is a single slot, 500 series compatible case and power supply.
It instantly turns any 500 module into a standalone unit.
It can host any API* 500 compatible module.
The 501 can be used vertically or horizontally. It is built to last, made of two vented pieces of 1mm black powder coated steel. All the threads are done with inserts.
Several 501's can be attached together creating a custom lunchbox.
The internal power supply is low noise, low radiation. It is made of a very high frequency, shielded PSU module followed by linear regulators for low noise and low ripple. The nominal input voltage is 12 Volts DC but it will work from 6 to 20 Volts. The 501 is delivered with a 12V power adapter.
The auxiliary stereo jack socket may be used in many ways. The tip and the ring can be individually connected to any of the 9 audio signals available on the 500 series EDAC connector. It is also possible to link 2 pins, breaking the link when a jack plug is inserted. It can be used as input, output, insert, side chain, stereo link, etc...
You bring the solder (use good quality solder, 1mm diameter max) and the Lunchbox.
The 501 kit is a medium difficulty level kit. Nothing really difficult but care is needed when assembling the shield and soldering the SMS regulator.
There is no setup, only a simple control with a voltmeter.
