What's New?

We've revised version 2.0 of the MNT Reform motherboard, fixing some bugs with the initial design as well as switching parts out based on availability. The main improvements are:

  • Lowered headphone lowcut filter for improved bass response
  • USB-C replaces microUSB as the LPC flashing connector
  • Lowered power LED brightness
  • Fixed current leak through balancing circuit that could bypass missing cells
  • Fixed main buck converter enable behavior under low voltage condition
  • Fixed charger control circuit that previously required a factory resistor bodge
