Open407I-C Zestaw rozwojowy z STM32F4 STM32F407IGT6

Open407I-C platforma rozwojowa z mikrokontrolerem STM32F407IGT6 składająca się z płyty bazowej do której podłączamy wszelkie peryferia oraz płyty Core407I z mikrokontrolerem, pamięcią SDRAM i blokiem zasilania.

Open407I-C umożliwia rozbudowę o moduły peryferii firmy waveshare np. wyświetlacze LCD, moduły ethernet, dodatkową pamięć, kamery itp. rozbudowę ułatwiają dedykowane złącza. 

Programowanie mikrokontrolera możliwe jest za pomocą portu USB komputera - adapter USB -> TTL znajduje się w zestawie.
