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
You wanna programm the Mega 4808 or an other megaAVR 0-series microcontroler? Then you need a UPDI programmer. You can buy the Atmel ICE for ~100$ or you can make your own UPDI Programmer.
You wanna use the Mega 4808 with MegaCoreX and Arduino? Then you need the standard pin usage / pinout for it.
You wanna get started with the Mega 4808 in Arduino and you do not now how? Here is your answer.
Every speaker builder now the moment when you have an idea for your own customized speaker and you are searching for an amplifier which fits the needs. Most of the chinese Amplifiers has a horrible background noise or large transient noise. Nothing is worser than to see your own build speaker which is ruined through a bad 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.
You want to know which is the minimal circuit for the ESP32 WROOM 32D and which are some interesting informations about the ESP 32 WROOM 32D for your custom design? In these post you can find the answer.
