Question DIY ESC onboard current logger

I want to measure and plot the current usage of my ESC during flight - Castle ESCs provide logging which has this info (I'm running HobbyWing), VControl has telemetry module which provides this (hooks up between battery and ESC - but I have Spektrum) and the closest for HobbyWing ESCs which I found is JLog module.

I want to just wire up this thing for morbid curiosity between the main pack and ESC for a few flights to make sure I'm not close to the limit of the ESC - is there a simple module on AliExpress or DigiKey which performs high current measurements safely?

Perfect! I can also use JLog to compare to ESC readings - thanks a lot!
