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.
