Can I use 2 tm1637 led strips on the same esp32 to display different values?

Question:
I want to make a 2 output power supply and read the output voltages of each. Can I use 2 tm1637 led strips on the same esp32 to display different values?

Mojeek:
Yes, you can use two TM1637 LED strips on the same ESP32 to display different output voltages from a 2-output power supply. To do this, you would need to connect each TM1637 LED strip to a separate I2C bus on the ESP32, and then write separate code to update the displays with the desired voltage values.

It is important to note that when powering LED strips, you should ensure that the voltage and current requirements of the strips are being met. If the LED strips have a forward voltage drop greater than the output voltage of your power supply, you may need to use a separate voltage regulator or driver to provide the correct voltage to the strips.

Additionally, when measuring the output voltages of the power supply, make sure to use a multimeter or other appropriate measurement device to ensure
