Arduino Upgrade Boards

Several STM32 boards exist from various designers that use the Arduino Mega footprint. These boards are designed as Speeduino upgrade boards, where you replace the Arduino Mega with a STM32 upgrade board and then run epicEFI.

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.

MEGA144H7

MEGA144H7

This upgrade board has been designed by ggurov and turboedge, originally inspired by pazi88 and sold by DCwerx. The board is green.

This board uses a 144-pin STM32H743 and has an onboard SD card slot and CAN physical interface.

The analog input buffers are onboard, but the board does not have output buffers (direct 5V drive).

Internal code: MEGA144H7

The MEGA144H7 is proprietary. For more information, including the pinout see MEGA144H7.
