    5 stars - The only issue to report is that the Cam C pad detached from the board. This may/may not have been due to my high temp soldering. No other issues.

    Ease of use: I couldn't find any videos or tutorials on this board which may make it difficult for first time builders. There is one pad layout/description image available from multiple sources. The pad layout makes complete sense and is well laid out. No reassigning uarts or extra programming steps. Its all there. Just solder and set it up to your specs. With patients, all levels should be able to find the answers to any questions regarding pad layout and function.
    Smaller pads will challenge experienced hands. If you can solder this board, you can solder anything without issue. I enjoy building so only change was using a magnifying lens from an old set of goggles to help me see some of my work when solder bled over to the next pad. Corrected easily. Just double-check your work with a ohm meter while soldering.
    Be prepared to buy, make a plate to retrofit this 20mm board to 25mm mounts if using it on anything other than a micro. I used spare 2mm carbon to make an adapter. Took 5 minutes.

    Flashed with Betaflight CLR4 3.3.1. Made my normal adjustments and turned on my normal OSD preferences with ease since pads were designated for ease of use.

    End result:
    Perfection. The Chameleon is ridiculously responsive when needed and has a super smooth transition and buttery flying. Because of the compact build size with the same function of most large FCs, I am going to predict that the new normal will be this size FC. I will do a build/flight video soon unless someone beats me to it. I don't think anyone knows that they can use this board for a 5". Don't be afraid to buy it now.
