M5Station-485 is a multi-purpose industrial level programmable embedded controller with Espressif ESP32 SOC, integrated Wi-Fi 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.
