I have completed my first test, and added the output to the files section.
To test recording I connected a portable monitor to the Lattepanda 3 Delta, with a USB and hdmi lead for power and display respectively.
I added a mini keyboard/trackpad using USB again for the receiver.
Last of the three USB ports I connected my Rode NT-USB microphone. This mic is a solid condenser mic which connects directly via USB without the need of an interface. Perfect for a single mono tester.
I installed Reaper as my DAW of choice, enabling the Web UI for it to allow for some control via my phone. I'm blown away how fast and snappy the Lattepanda is. I wasn't sure what to expect with Windows 10 being such a large OS, but I was really impressed. Adding the WiFi antenna was a fiddly affair but I suspect it was my large fingers causing the issue there, but once connected it held its connection to my network well.
Next up will be to switch the mic for an audio interface and try tracking a few channels at once. I would also like to add an m.2 ssd to give more storage for recorded audio.
