Due to issues with shipping to the US from the EU introduced by the latest tariff changes, I’m aiming to make all products available from the official partner, Elecrow. Today’s addition is an Esparagus Echo, Duo version only. I’m reviewing the Solo design at the moment, considering the idea of hosting it in the IKEA […]
Nice video review of the Louder-ESP32-based project performed by tmuWolverine
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 […]
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 […]
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
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 […]
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 […]
Small update on the standalone snapclient firmware for the TAS5805M/TAS58025M-based boards Recently, some nasty bug popped up in the firmware; the fault check and reset task that was added recently started to crash because of a lack of stack space, affecting both master and develop versions. The proper fix is on review right now, but […]
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 […]
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 […]
