Zestaw rozwojowy z STM32F7 STM32F746IGT6 Zestaw B

Open746I-C platforma rozwojowa z mikrokontrolerem STM32F746IGT6 składająca się z płyty bazowej do której podłączamy wszelkie peryferia oraz płyty Core746I z mikrokontrolerem, pamięcią SDRAM i blokiem zasilania.

Open746I-C umożliwia rozbudowę o moduły peryferii firmy waveshare np. wyświetlacze LCD, moduły ethernet, dodatkową pamięć, kamery itp. rozbudowę ułatwiają dedykowane złącza.
