Flip32 F4 = Airbot F4 = CC3D Revo
Have yet to fly the board but everything seems to check out in GCS and on the ground. Flash using revo target (of course!).
No mag or baro. Output 6 does not correspond to the same pins on a full revolution board so is effectively useless. I have not tested any of the uarts. There's no red warning led connected only a green power on and blue status.
No idea why they didn't break out the I2C1 pins at least to a pad. From what I gather here, dronin does not support I2C2 or I2C3 and neither do other firmware other than inav. Are there any plans for automatic bus selection? Hopefully my remap of the i2c to effectively the one found on the revolution flexiport works.
One other observation, the board (my ebay version anyway) looks like it's put together ok, but I wouldn't call it very well made. It's also quite fragile I managed to knock the top of the status led off and will have to find a replacement at some point.
The biggest point though about this board is the price. US$16 on ebay is cheap enough for a play, but have to remember that adding an MS5611 will cost half as much as this.I'd be happy to get an F4 omnibus from rtfq but the shipping would be a killer (I'm not in the US).
