There are not so many options for AES3 from a Pi HAT, and no others at this price.
Despite the item showing as out of stock and estimated delivery of 5 weeks, it arrived 10 days from ordering.
The only negative relates is the documentation (reason for dropping one star). The documentation is what is on the product web page, and on the silk screen of the PCB (for jumper positions). What is missing? I'd like to have known output voltage level for AES3 to understand viable cable lengths without risk of decoding errors, and a dimensioned drawing of the connector positions and sizes as there is no off the shelf enclosure solution for this HAT (needs to be at least 50mm deep).
Regarding performance & functionality, after setting the power supply jumpers and configuring Moode Audio, it worked first time.
In summary, great to have something quite specialist like this at this price point.
