Open746I-C Standard - set with STM32F746IGT6 microcontroller + accessories

Description

Module with the STM32F746IGT6 microcontroller, including a base board and accessories.

Core746I is a development kit with a microcontroller from the STM32F746IGT6 family (ARM Cortex-M7 core). The board is equipped with the basic elements needed to run the system, as well as configuration switches and a reset button. The user has all the pins of the system connected to pin connectors with a pitch of 2.54 mm. It is powered by a microUSB connector and programmed via a JTAG or SWD interface. There is no debugger on the board, so the kit requires an external programmer/debugger.
