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…

Louder Raspberry Hats are now available at Elecrow
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 expensive with UPS – not only do they charge $40 for shipping, but also an…

Amped-ESP32-Plus and Loud-ESP32-Plus are now available at Lectronz
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 models I’m currently using. PCM5122 is a DSP-enabled version of my favourite PCM5100 DAC, so…

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…

Amped-ESP32-Plus is now available at Elecrow
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 batch is based on the TPA3110 amp. The reason for this change is not the…

Start of sales on Lectronz
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 everything from scratch and do a full stock revision. Most of the ESP32 boards are…
