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…

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

Retro Pi Handheld Guide
As a side miniproject, I just finished making a small (tiny, actually) handheld game console, based on a Raspberry Pi Zero 2W and a Waveshare GamePi13 HAT This small build doesn’t use any of the Soncotta parts, and I do it solely for research purposes. It takes some effort to make the TFT, buttons, and sound…

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…

New onboarding experience for Esparagus boards
A new and updated web installer is now available on GitHub Pages for Esparagus devices. What is new The above approach was shamelessly copied from the voice-pe repository and replicated for each supported board.

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…
