Measure High Dc Voltages 0-150V using a STM32F446RE MCU
Hi all, Does anyone have any suggestion on how to build a circuit that can convert high Dc voltages from 0-150 V to lower voltages so that i can use my MCU to read them and display them on my 16x2 LCD?

Sounds a bit dangerous for a 3.3V A:D input pin. Is 150V the absolute max Voltage? What's the output impedance/current of your 150V supply? Is the range 0 - 150V or something different?
