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…

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…

Beta support for equilizer on PCM5122
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 a much more complicated DSP engine, with 15 BQs per channel, and fairly good support…

New revision of the Amped-ESP32-S3
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 replace the TPA3110 amp used on the earlier revisions for three reasons Unfortunately, I found…

Esparagus working with Snapclient
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 audio playback protocol with a specific focus on near-perfect sync. Normally, you need to have…

Esparagus with AirPlay-2
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, with the possibility to play directly on Apple devices or integrate with Music Assistant. The…

Using Squeezelite with Esparagus boards
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 ago, LMS (Logitech Media Server) ruled the hacker’s audio world for years, offering a powerful…
