New onboarding experience for ESP32 audio boards
Following last week’s update, ESP32-based audio development boards receive a new firmware web installer It works in a very similar way; you get Sendspin firmware as a default recommended choice, but both 16-bit and 32-bit squeezelite-esp32 variants are available as well. Speaking of Sendspin, once you have firmware installed, you’ll onboard wifi using the same…

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…

AirPlay 2 support for Sonocotta boards
In case you missed it, there is a great piece of ESP32 software that popped up recently, called Airplay-ESP32. A key feature of that is an Apple AirPlay 2 protocol implementation. V1 was implemented some time ago as part of squeezelite-esp32 firmware, and I think it is a good alternative to a Bluetooth player on…

TPA3128 design errata
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…

Louder-ESP32-mini launch at Elecrow
The Louder-ESP32-mini is now available at Elecrow, starting with the 42mm version, but the larger 55mm version will be available soon as well. The EU stock will be refilled as well, but it will take some time, as I just finished testing the 55m prototype, and after cosmetic changes, it goes into a larger production…

My Louder-ESP32-Mini build
A quick video about my own test setup with two Louder-ESP32-Mini boards (S-model and M-model). Speakers that were used in this build are second-hand M-Audio and no-name brands; they cost me around €10 each plus delivery. Software used in this build ESPHome configs can be found on GitHub

Amped ESP32 and Amped ESP32 Plus with TPA3118 amp
I just received the latest revisions of Amped-ESP32 and Amped-ESP32-Plus boards, all based on the new TPA3118 amp schematics, finally finishing the design upgrade for every Amped board. Risking repeating myself, reasons to change to the new amp are noise issues with the TPA3128 design on the Amped-ESP32, and the inability to work with the…

Louder-ESP32-Pro launch
Louder-ESP32-Pro has finally passed all tests and is ready for launch. Over the last few weeks, I tested the peripheral, starting with that pretty standard now (DAC, Ethernet, IR, RGB, Mic, USB-PD), and then new ones: TFT and Fan controller. As usual, I made a small mistake, it is around the TFT backlight pin, but…
