4. reading 66khz two 12v signal with a core.

reading 66khz two 12v signal with a core.

  • B

    I want to read the signal of 2 laser sensor that work at around 12V. is there any bases that would help me to easily:

    1. give me the 2x 12v 0.4A I need
    2. convert the 12 v signal to 3.3 v so I can read the sensor signal on a Core.
      is there any product of m5stack that can help me on this or shall I fully construct the circuit:
      with a 12v power supply and a 12V to 3.3V Digital Logic Level Conversion Module ?
