Now you can have a look at a partially populated JackAl board thanks to this photo from Jack W8TEE in response to a question about a LA4425 as a replacement to the TDA2822.
The highlighted square in green is the audio amp stage of the JackAl board: a 7W TDA7266M. Seems like you could really blast the neighbours with that one!
In case you haven’t figured out what the JackAl board is about: it is a supplementary board that hsould be released in the next few weeks by Jack and Al, that adds a Teensy 3.6 processor, and a number of other mods, all on one board. The Teensy will give the µBITx new features like DSP.
