Ethernet-enabled Sendspin configs on the web installer
Both esp32-audio-dock firmware web installer and esparagus boards web installer got a slightly controversial update today: Ethernet-enabled configs. Let’s start from the basics. The factory image right now is three images for almost every board: (1) default image that relies on WiFi, (2) same but with OLED screen enabled, and (3) Ethernet-enabled image that has…

Louder-ESP32-Pro is now available at Elecrow
The Louder-ESP32-Pro is now available for purchase at Elecrow, my production and distribution partner. It comes only in an ESP32-S3-based variant. Optional power adapters and TFT screens are coming soon as well.

Screen-enabled Sendspin factory images
Until recently, all Sendspin factory images available at the web installer for Esparagus boards and ESP32 development boards had a single Sendspin image with both Ethernet and OLED/TFT screen disabled by default, since most of the customers don’t have those options installed, and configuring them in that case would create pointless overhead of trying to…

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…
