M5Station-485 is a multi-purpose industrial level programmable embedded controller with Espressif ESP32 SOC, integrated Wi-Fi and 'BT' solution, dual core low-power Xtensa® 32-bit LX6 microprocessor, main frequency up to 240MHz.

Onboard 16M FLASH, integrated 240*135 1.14" full colour HD IPS display + physical keypad + rich peripherals, two sets of six expansion ports+ Low-power sleep/wakeup function. Multiple power supply options USB Type-C, PWR485, External Battery (battery socket reserved on board). The integrated high power density boost DC/DC converter SCT12A0DHKR on board ensures the stability of the electrical equipment even in complex applications. This device is suitable for industrial control, intelligent buildings, multi-channel data acquisition nodes and prototyping applications.

Driver Installation

Click on below link to download the driver for your operating system. After extracting the zip package, select the installation package that corresponds to the operating system bit number to install. (CH9102_VCP_SER_MacOS v1.7 may report an error during the installation process, but the installation is actually complete, just ignore it.) If you are unable to download the program properly (timeout or Failed to write to target RAM), you can try to reinstall the driver.
