What is the recommended means of powering ATLAS?
A. The LPU or Demeter (not available yet). The ATX 20 pin power connector on the Atlas board enables the use of standard PC power supplies. (Please Note: There is no reason that you cannot utilize a non-PC power supply regulated and wired to provide the proper voltages to the 20pin connector. A non-PC power supply could also enable custom current limiting of the voltages going to the 20 pin connector, an advisable setup when testing or prototyping boards plugged into ATLAS. An analog power supply may be an attractive option for users particularly concerned about spurious emissions in the HF band which some low cost PC power supplies may produce.) If you choose to use an ATX computer power supply care should be taken that the -12V current requirement is met. (Note of warning: some versions of the attractive picoPSU do not provide proper -12V current capacity.
