The PCB for the ESP32 frontplate is done and works. Now its time to build a enclosure for it.
For a time i build the iniversal audio amplifier with a PT2033 which can be programmed over I²C. Now its time to make a frontpanel to control this amplifier
Every microcontroller must be programmed. For this you need a programmer. In this Post i show you how the circuit for a ESP 32 programmer should be.
