ESPHome component for HUSB238A PD-trigger chip
I just published a custom ESPHome component for a Hynetek HUSB238A USB-PD trigger chip, which is part of the 55-mm version of the Louder-ESP32-Mini board. Originally, when I prepared a design for this board, I selected this chip to support both “dumb” mode, where it would simply request the required power profile on boot, and “smart” I2C-controlled…

Recently, I received a hint from a community member that noises and pops on the TPA3128-based Amped boards that I wrote about a few times can be fixed simply by changing the modulation mode to BD mode. Since every board based on TPA3118/TPA3128 amps has solder jumpers allowing changing the modulation scheme, I went to…
