Review on 🔋 DEVMO 2 Pcs High Voltage Boost Converter: Efficient ZVS Step-up Booster Module (8-32V to 45-390V DC-DC) by Andrew Roll

No documentation but a search for YH11068A turned up some information including a reconstructed schematic and some noise analysis. When delivered, it is configured for operation with 10-32 VDC. To reconfigure to 8-16V it seems it is necessary to rearrange the soldered jumper, but there is no clear indication of what needs to be rearranged and it's all overhead. The claimed continuous output power is 40 watts, peak - up to 70 watts. The output voltages, both positive and negative, are independent of the input voltage and are adjusted with a 10-turn potentiometer. It runs at 75kHz and uses half-wave rectifiers, so don't expect it to be particularly quiet electrically. That's enough for what I need.
