STM32 H7 Adapter board – Arduino Mega 2560 Footprint

Description

STM H7 Adapter Board – Direct Drop-In Upgrade for SMD Speeduino ECUs

Unleash 32-bit power in your Speeduino with the STM H7 Adapter Board — a high-performance, plug-and-play replacement for the Arduino Mega 2560. Designed with the same footprint as the Mega, this adapter makes upgrading simple and seamless.

Powered by a 32-bit STM32H7 processor running at 480 MHz, it delivers massive speed, processing, and tuning improvements over the original 8-bit Mega 2560. This board allows you to run alterative firmwares such as Epic EFI or rusEFI, bringing modern performance and flexibility to your existing setup.

Every board comes preloaded with epicEFI firmware an a generic basetune to ensure a quick and easy transition.

Important: This adapter is only compatible with SMD (Surface-Mount Device) Speeduino boards.

Features:

Direct swap for Arduino Mega 2560 footprint

Compatible with SMD Speeduino boards only

Supports EpicEFI and rusEFI firmware

32-bit STM32H7 processor @ 480 MHz

Dramatically faster response and improved data handling

Plug-and-play upgrade — no rewiring or hardware changes required

Perfect for: Speeduino builders, tuners, and enthusiasts looking to upgrade their ECU with next-generation performance and alternative firmware compatibility..
