MEGA144H7

The MEGA144H7 is a Speeduino upgrade board designed by epicEFI and sold by DCwerx that uses a 144-pin STM32H732. The board has several notable features:

  • Inputs are buffered from 5v to 3.3v for direct sensor compatibility
  • Onboard SD card slot
  • Onboard CAN physical interface (uses the I2C pins)
  • Onboard 3.3v voltage regulator
Please be advised that not all Speeduino boards are supported. The deciding factor is the on threshold of the MOSFETs and gate drives for ignition. For example, the STP62 on the Speeduino 0.4 and 0.3 boards are not supported, while MOSFETs on the UA4C are supported. Check the respective MOSFET datasheet and look for the "ON threshold" or "Gate threshold". It should be less than 3V.
