It is a really nice aio board, I used it to build up on the Diatone R349 (tight fit), the iFlight Chimera 4 (fits perfect) and the Flywoo Explorer LR 4 (does not fit in normal orientation, but flipped 90° or -90° it fits just fine, except access to usb port is restricted then). I really like the connectivity options (perfect if you want to use DJI FPV stuff + CRSF + GPS), the only thing you might be missing is SCL/SDA pads and built-in barometer. But hey, with the reasonable pricing I think this is a really good choice for small builds or analog-digital-conversions. The product description says it does not have Blackbox but as also others have reported IT ACTUALLY COMES WITH 8 MB OF FLASH MEMORY / BLACKBOX, that is really cool!!
