I can't seem to find any manufacturer info.
Attached a picture of the backside of the mainboard.
On the controller casing it says:
"Controller for brushless motor: ACZ120112
CE: SHEM01011014901
EBC-KTCO67C BST-LSG12039001"
Hi ambroseliao,
I didn't know where to focus on, but see attachment for 2 pictures of the mainboard.
Thanks for your help and look forward hearing if it's possible!
