VOXL ESC Mini 4-in-1 with Built-in Power Module

There's no info on how much you can output to the motors, and if it's possible to step up voltage.

With the M0134 at least it's listed as 4 channels with 10A continuous. But that can't be used to power two servos or a VOXL 2 mini...

@Bilal-Hussain , can you please clarify:

"if it's possible to step up voltage." - what do you mean? which voltage?

Regarding maximum current per motor, the mini ESC can output continuous current at least 10A per channel at 15-16V input battery voltage (we tested at 15A+ with direct cooling from the propellers). The mini ESC is recommended for small drones 300-500g range or small fpv drones (300g). Maximum input voltage is 16.8V (4S LiPo). This ESC is very small, so when you are building a new drone, you should conduct tests to monitor the ESC temperature which should to stay below 80C. If you are exceeding that and getting close to 100C, it is a bad sign. The ESC should be rated to operate at least 110C but if you are getting that hot, it is a sign that something is wrong (motors are drawing too much current for the ESC or insufficient cooling).

We typically use the mini ESC in the drone designs that use less than 5A per motor during hover and may reach up to 15A per motor at full thrust for some time.

The ESC reports temperature via UART feedback and it is available in PX4 esc status message.

We will update the current specifications in the datasheet (https://docs.modalai.com/voxl-mini-esc-datasheet/)
