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.

I’ve shopped a few different stores for drone products. Newbeedrone has the fastest shipping and great pricing. Best customer experience I’ve had in the drone world.
I tried them because they were on sale and it turns out that they’re good so I bought two more sets. I’m using them in 65mm builds but I’ve tried them on my 75s and they’re good for that size too. They are very responsive so I’m able to toss and float for a while and then catch full throttle last second without any issues. I haven’t had them long enough to comment on their durability but I haven’t destroyed one yet…
