THUNDERBALL H7 OEM : Industrial & Marine Rugged IP67 Calculator / IoT Gateway – STM32H7 Ecosystem

Ultra-small form factor, Hard Real-Time & Robust platform for Industry, Marine, & Drones

THUNDERBALL H7 OEM : Industrial & Marine Rugged waterproof IP67 Calculator / IoT Gateway – STM32 Ecosystem

The Thunderball H7 OEM allows you to build your next smart project rapidly using a connected platform based on the powerfull STM32H743 ARM MCU running at 480Mhz. It is the ideal solution for a hard real-time and robust systems with browser-based remote displays and operating in harsh environments. If a high level of integration is required, the bare electronic board can also be integrated into your system.

Key Features

The Thunderball H7 OEM is a high performance microcontroller based SWaP-C platform : Industrial with a wide temperature range, marinized IP67, miniaturized and very lightweight (Only 165g) , very low power consumtion, cost-effective.
It integrates a powerful 32 bits ARM with DSP&FPU, many Industrial, Marine, and Transportation field buses, Galvanic isolation, Protections, Watchdog, RTC with GNSS Time synchronisation, a huge possible storage for your datalogs (uSD card).
