HiFi Plus Hat for Raspberry
I’m introducing a new Hat in the Raspberry family of devices: HiFi Plus Hat. Compared to the base design, what Plus does is – Upgrades DAC to PCM5122 model (adds digital volume for better performance at low volume; analog gain control; basic DSP with 6x BQs and DRC; better SNR figures) – Added onboard ADC…

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…

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…

Audio Brick production progress update
Hey folks, quick update on the production process after a slightly longer-than-usual break. Despite the summer holidays, as soon as we got the funds transferred, we were able to submit the order for production. Thanks to Elecrow’s flexibility, we were able to start with just two board samples, one per board version, and after just…

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…

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…

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…

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…
