usage notice
There are many integrated functions of the flight control, and the components are very dense. When installing, please do not use tools (such as needle-nosed pliers or sleeves) to screw the nut, which is easy to scratch the tower hardware and cause unnecessary loss. The correct way is to tighten the nut with your fingers and the screwdriver can quickly tighten the screw from the bottom. (Remember not to be too tight, so as not to damage the PCB)
Do not install the propeller during installation and commissioning. Before installing the propeller, please check the direction of the motor steering and propeller again. Do not use non-original aluminum or nylon columns to avoid damage to the flight control hardware. The official standard is a custom-sized nylon column for the fly tower.
Before the power is turned on, please check whether the installation between the towers is correct (it must be arranged with the pins or cables aligned), check whether the positive and negative poles of the welding are correct, and check whether the motor screws are against the motor stator to avoid short circuit. Checking the electronic components of the tower for soldering out may result in a short circuit. If the short circuit occurs in the installation soldering, the buyer is solely responsible.

1. When inputting DSM, IBUS, and SUBS receivers, configure RX1 as the input interface.
2. The PPM receiver does not need to be configured with a UART port.
2S10A four-in-one ESC parameters:
Input voltage: support 1S-2SLipo and HV-Lipo

Update to my earlier review:

Much as I wanted to like this stack, I'm finding it troublesome. I have two, both behave the same, so it's unlikely that I just have a bad example. You can work around the weak 5V regulator with a stand-alone BEC to supply the camera and vtx, but the ESCs also appear to be problematical. They are fussy about which motors they will drive at all - I have a 1106 motor that neither board will run, but that flies fine with other FCs, including AIO 5A boards. Other motors I have tried fly fine for 15 to 20s and then the quad loses power and sinks to the ground. I suspect thermal shutdown on the ESCs. This happens with motors which should be drawing well under the rated current when flown gently at hover on 2s. Maybe it will fly with some low kv 080x motors, but overall the board seems extremely limited. I'd recommend avoiding this one.

This seems like a great stack for a small build, it has more IO than most similar boards and the ESC seems decent. However, watch out for the limited output power of the 5V BEC. I'm having trouble finding a VTX/camera and RX combination that I can use with this board. The 5V sags to around 3V or less after a few seconds, presumably when it enters thermal shutdown. I'm looking at adding an additional 5V regulator, but that's a messy solution to the problem.
