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.… Read more: Louder-ESP32-Pro 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… Read more: Louder-ESP32-mini launch

I invite everyone to beta-test BQ-filters support on the PCM5122 DAC. Right now, it is available via the ESPHome driver, and work on snapclient is ongoing. First implementation of the BQ-filters I did on the TAS5805M DAC, and it definitely has… Read more: Beta support for equilizer on PCM5122

New revision of the Amped-ESP32 just came out. There is just one difference compared to the previous board – the TPA3118 amp came in to replace the TPA3128. The TPA3128 is a better amp on paper, and it came to… Read more: New revision of the Amped-ESP32-S3

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… Read more: Audio Brick Dual DAC prototype

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… Read more: Hifi Esparagus S3 – revision H is in stock

This is a copy of a post prepared for the Esparagus Audio Brick Crowd Supply campaign. After achieving multi-room sync with Sendspin, squeezelite-esp32, and Airplay-2, it is time to look at snapclient, which was, until recently, the only solution. Snapclient is an open-source remote… Read more: Esparagus working with Snapclient

This is a copy of a post prepared for the Esparagus Audio Brick Crowd Supply campaign. In the last update, we used Squeezelite-ESP32 firmware to play audio via the AirPlay protocol. It is a great way to listen to music over wireless,… Read more: Esparagus with AirPlay-2

This is a copy of a post prepared for the Esparagus Audio Brick Crowd Supply campaign. Introduction I think it is safe to say Squeezelite-ESP32 is the second most popular option when it comes to connecting ESP32 and audio. But not so long… Read more: Using Squeezelite with Esparagus boards

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… Read more: Esparagus Audio Brick Voice Assist

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… Read more: Audio Brick Dual DAC prototype work

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,… Read more: Voice-Assist + Sendspin ESPHome configs

Both variants for Louder Raspberry Hat Plus – 2.0 and 2.1 are now available at Elecrow, my official production and fulfillment partner This would be especially useful to folks in the US, since delivery from the EU is now really… Read more: Louder Raspberry Hats are now available at Elecrow

Full-size batch of Amped-ESP32-Plus boards finally came from the factory, and they look really nice and sound great. The main goal for this board to pop-up is to combine the PCM5122 DAC with the TPA3128 amplifier, both being the top-of-the-range… Read more: Amped-ESP32-Plus and Loud-ESP32-Plus are now available at Lectronz

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… Read more: Esparagus ESPHome Integration

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… Read more: Updated Sendspin configs for ESP32 devices

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… Read more: Infineon MA12070P DAC support

Hey folks. Amped-ESP32-Plus is finally available. Exclusively at Elecrow at the moment, but another package is heading to Europe as well, so sales via Lectronz/Tindie will follow right after. While the first prototypes were based on the TPA3128 amp, this… Read more: Amped-ESP32-Plus is now available at Elecrow

The TAS58XX drive on Raspbian is both beautiful and problematic at the same time. It is one of the few drivers that allow on-the-fly DSP configuration, and it gets stored and re-applied on restart completely effort-less. And you have both… Read more: One-command install script for Raspberry

Due to the Tindie outage, I’m moving my shop to Lectronz. I’m planning to open sales at Sonocotta.com as well (where I had to spend 2 days moving everything to new hosting), but it would take some time to configure… Read more: Start of sales on Lectronz

Hey folks. I updated sendspin configs for the Sonocotta boards to use the latest stable code in this PR. Hope that might help with testing it. Updated configs are for Esparagus boards, ESP32 audio boards, and Esparagus echo.  My own… Read more: Sendspin updated configs
