Zest_Core_STM32G474VET

Overview

The Zest_Core_STM32G474 is an electronics development board for 6TRON opensource platform based on STMicroelectronics STM32G474 microcontroller.

The STM32G474 is a 32-bit Arm Cortex M4 core (with FPU and DSP instructions). The frequency of the core can reach 170MHz with 213 DMIPS. It integrates 512 Kbytes of Flash and 96 Kbytes of RAM.

The Zest_Core_STM32G474 features a high density 80-pins interface header integrating configurable standard communication interfaces (at least 1 SPI, 1 I2C, 4 Analog, 1 UART, 1 ICAP, 3 PWM, 36 DIO, 1 Reset and 3 Power supply pins). See 80-pin 6TRON header.
