Heatbed Voltage and Current Specs
Simple question. Since the mini uses a custom board I can't find any info online for what voltage and current the print bed uses. I'm looking to make some mods and I can only find the Einsy Rambo specs which list it as 15A at 12-24V. I'm guessing the mini has similar specs, but I want to make sure.
Happy Printing,
Jack

I have not tested it but if no one response by Tuesday, I will measure it.

RE: Heatbed Voltage and Current Specs
Would add additional question.
What is max or expected power output on the ESP connector planned ?
Would ESP-01S (only) be sufficient to power ESP32CAM(wifi+cam+sometimes LED-flash) ?
ESP-01s: max 170mA + spikes up to 400mA 3,3V
ESP32-CAM: max 150-310mA [5V], has also input for 3,3V
Would like to use it as passive stationary live camera, maybe even add relay (5mA x 5V ) to start/stop LEDs (different power supply) via web button on website.

Hello and welcome to the Prusaforum!
The mini power supply delivers max. 160 Watt. The nozzle requires 40 watts at full power, leaving 120 watts for the printing bed theoretically, but less in practice. Since the voltage is 24V, a maximum of 5 amperes flow there.
Circuit diagram of the Mini can be found here: https://github.com/prusa3d/Buddy-board-MINI-PCB/blob/master/rev.1.0.0/BUDDY_v1.0.0.pdf
