Default cheap aliexpress/ebay ADAU1452 development boards

there's a bunch of cheap adau1452 boards on aliexpress and ebay lately.

aliexpress

ebay

some of them come with daughterboard "4IN8OUT_CODEC", some do not.

it was not obvious to me that you need an extra device to interface with the board, a USBi interface. the ADAU1452_DSP comes without the 2x5 header pins installed, which baffles me as to how they intended this thing to be used without it!

the official EVAL-ADUSB2EBZ interface can be used, though it is a bit pricey.

there appear to be cheap chinese USBi clones on aliexpress. not sure if they are compatible though.

the ADAU1452_DSP boards come with several empty spaces on the board, from the schematics it appears they are missing an STM32F103C8T6 (IC6), a 23LC1024 (IC7), and an 8mhz crystal (X2).

Hi,
I confirm that the board/codec works. (Well...at least mine works...)
I used it as the digital crossover for Linkwitz Lxmini.
But the documents are very limited and you have to find your own way (crosscheck the broad with the ADAU1452 Evaluation Board, they are very similar) to make them work.

Are you positive that any of them come with the "4IN8OUT_CODEC" board? I know some show a picture with both boards, but I don't see any mention of the codec board, just "1 x NEW ADAU1452_DSP development board, learning board". Just don't want to get burned.

To me with this listing 4 in 8 out electronic frequency divider, /IIS audio processing, /DAC decoder board-in Contactors from Home Improvement on Aliexpress.com | Alibaba Group it looks like you can buy the CODEC board individually for $38 or both boards for $71 by selecting the "color"

Hi all.
I am interested too but do we require a programmer as well and where is the best information source? I am not exactly sure what the 4 in 8 out codec board is. Would like to use for Linkwitz LXMinis.
Thanks

Hi, just like the connection show in the figure.
The USBi card, 3:I2C SCL, 5:I2C SDA, 12:GND connect to adau1452 card, SCL, SDA and GND.
In SigmaStudio, hardware configuration, choose I2C 0x76 (118) to connect to ADAU1452 and I2C 0xAE (174) to connect to E2Prom.

I think the boards are for developers. I still recommend using MiniDSPs for Linkwitz LXminis.

Thanks, I didn't notice the "color" option. For those who have bought the combination (DSP & 4in/8out boards), what are your experiences? Thumbs up or thumbs down?
