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…

Louder-ESP32-mini launch
The Louder-ESP32-mini is finally available at Lectronz and Tindie. Well… kind of. It was sold out in a day, since I only had 10 boards from the first test batch, and I want to keep one for myself (for reasons explained below). One of the goals for this board was to be affordable. I think…

Audio Brick Dual DAC prototype
I just got my hands on the new Audio Brick prototype, which is the first in the ESP32 family that has two DACs on the board. Both DACs use the same I2S bus, so they are exposed as a single device to the application, but having the second DAC has its benefits. The main motivation…

Hifi Esparagus S3 – revision H is in stock
New revision of the Hifi Esparagus (ESP32-S3 variant) just came from the factory, and after some testing, it is available for purchase from Lectronz and Tindie (Elecrow availability comes later during the summer). The reason for redesigning the board was the weirdness of the USB-serial on the ESP32-S3. One of the features of the S3…

Esparagus Audio Brick Voice Assist
This is a copy of a post prepared for the Esparagus Audio Brick Crowd Supply campaign. One of the reasons to make an ESP32-S3 version of the board is the more advanced architecture of that chip, which allows for on-chip wake word detection. Similar to the Home Assistant Home device, the Esparagus Audio Brick can…

Audio Brick Dual DAC prototype work
One of the great features of ESPHome is its modularity. Idea that popped up some time ago – can I make an ESP32 board with two DACs, similar to Louder Raspberry Hat 2X? Hardware is not the issue, but software that would work right out of the box with two I2C-controlled DACs is not something…

Voice-Assist + Sendspin ESPHome configs
A person from the community reached out recently asking if it is possible to add Sendspin configuration for voice-assist config. Esparagus Echo, or any other ESP32-S3 board that supports voice-assist. After some poking, it turned out that it is possible, and two experimental features work surprisingly well together. Wake-word detection works, TTS works, and audio…

Esparagus ESPHome Integration
This is a copy of a post prepared for the Esparagus Audio Brick Crowd Supply campaign. Introduction The Esparagus Audio Brick was created specifically with the smart home in mind, and although there are a number of alternatives on the market, I think the most popular one is Home Assistant. And the most popular (and easy)…

Updated Sendspin configs for ESP32 devices
Small update on the ESPHome configs for Sendspin media players. Until now, existing configs worked relatively well on the ESP32-S3-based devices – I guess Sendspin developers used them mainly, so it was working quite well from the start, and recent releases had nothing to wish for – they just work flawlessly. It was a different…

Infineon MA12070P DAC support
I finally found some time to work on the Loud-ESP32-Plus boards, which have been lying on the desk since January. While hardware was not a big issue, software support turned out to be a bit more complex. Snapclient support My first take was to use the snapclient component, which supposedly existed already. As it turned…
