==== Known issues / modification ideas ====

  * TPS54160 [1.5 and below] only accepts 56V safely, for more input voltage, trace cut method must be implemented, see [[:m365-trace-cut|here]]
  * SY8502 [2.1 and above] accepts up to 85V input, 65V safely
  * TO220 MOSFET packages are poorly thermally connected to the case, see [[:m365-esc-cooling|here]] for possible improvements
  * B+ rail has poor electrical conductivity, see [[:m365-trace-cut|here]] for a fix
  * Phase connectors are known to be improperly crimped, it’s advisable to solder wires directly and attach MT30 or MT60 for better contact
  * Excessive braking current can burn MOSFET packages, due to active brake implementation
