The powersupply should output 5VDC and should be able to supply at least 0,4A. The powersupply needs to be low noise (<200mVp-p ripple and noise).

The following powersuplies should be suitable for many applications:

• Recom RACM18-05SER/W – IP68, compact
• Meanwell GS05E-USB – Wallwart, USB A output connector
• Meanwell IRM-30-5ST – Enclosed/insulated industrial PSU

Note: Flip the power switch on the PCB to “USB”.
