Product Brief
CAN PMU lite is a CUAV standard version of the power management module, built-in STM32F412 processor, supports 10~62V voltage input and 5.4V/4A regulated output. Compared with HV_PM, it uses advanced CAN bus communication and supports standard UAVCAN protocol. PMU lite has built-in ITT temperature compensation algorithm and performs factory calibration to ensure the consistency of measurement results at different temperatures.

Update process is cumbersome, better if done with the VTX out of the quad. Also the update port is much flimsier than the earlier 2 antenna versions, IMO.
I use this mont for all my builds with a DJI O3 system. It comes with all the hardware nessassery and I like how is provides a small gap between the frame and the air unit so you can run wires under it. With all that said, it is still very low profile to fit on builds that use short 20mm standoffs too.
This thing is really fun and I haven't had to touch the PIDs at all. Super maneuverable on high rates and really mellow on low rates. I'm teaching my six year old grandson how to fly and he's doing great with it then raise the rates and I doing freestyle in my livingroom. Top off the performance with Newbeedrones awesome customer service and you can't lose. Newbeedrone is now my go to site for whoop stuff.
