PSU Pre 2016 – External power supply for DAC-preamplifier

Dual Trafo Board and SmartPSU3 modules
Two 3-channel power outputs for DAC-preamplifiers, total current capability being approximately:
- +14 V, 250 mA
- -14 V, 250 mA
- +7 V, 500 mA
Over-current, under-voltage, and over-temperature protection provided by SmartPSU3
- Error codes blinked by the front LED

This is the device where Dual Trafo Board and SmartPSU3 were originally designed for – external power supply that is simple yet provides some protection in case something goes wrong in the target device. Its current output capabilities are somewhat limited but enough for small DAC and preamplifier. It was designed for HP Pre 2016 although headphone output power may be somewhat restricted with this power supply.

Designing Arduino-compatible board

I have stated some of my boards as “Arduino-compatible” as many other DIY and commercial electronics you can find nowadays. Simply put it means that you can develop Arduino programs (sketches) for that board with the Arduino IDE. Here are some information and references how to make a board Arduino compatible and what it means.
