Everything you need to know about: The Thor301

The Thor301 is a 20s (84v) VESC that is a successor of the Thor300. This controller is the flagship controller in Fungineer related products such as our Complete Controller Box modules and preassembled boards. This controller was built by and for the Vesc based, Onewheel community. Thank you to all the individuals who have greatly contributed to this controllers formation, some important names like Surfdado, Mario Contino, Nico Aleman, and many countless others. Your commitment to supporting this community hasn't gone unnoticed.
