Electrical Isolation HMI Development Board

Overview

EEI TECHNOLOGY RT300-MKV-EXTREME PACK#3 item

This module has electrical isolation characteristics to prevent the microcontroller from running away due to interference.
Now used in the display panel of RT300-MKV-EXTREME.
SPI data transmission, up to 8Mbit/s, and has electrical isolation.
The onboard high-speed processor ESP32, 240M main frequency and 80M SPI rate can make the refresh rate comparable to the 8bit FMSC parallel port of the STM32F1 series.
The division of labor is clear. Considering that when ESP32 uses Arduino as the development environment, Arduino does not provide support for SPI Slave, so the onboard STM32G030 is responsible for the data bridging task.
