There may by a related issue. machine,lightsleep() does not seem to work. When calling it for e.g. a 10000 ms sleep, the power consumption drops for about 1-2 seconds and then goes up again, sometimes not initializing the USB interface again.
WiFi was disabled during that test.
Besides that: at the same frequency the '722 seems slightly faster than Pyboard 1.1, but benefits form larger RAM and faster flash access. And WiFi is working well. My little FTP server works without change. So I can use that for file transfer, avoiding cache problems when using the mass storage mode. I'm waiting for the repository to a my favorite scripts to frozen byte code.
But .. for my fingers it'a a little bit too tiny. A slightly larger form factor with 1/10" pin connections (DIL32 size) would be easier to deal with. You can get that with the adapter board(s), but that adds connectors which a subject to cause trouble, And I do not see what the soldering notches are good for, if the bottom side is not flat. Obviously you can make versions w/o the W connectors and the SD card interface to be soldered to another PCB.
