The M5Stack Station ESP32 IoT Development Kit RS485 Version ('M5Station-485') is a multi-purpose industrial-level programmable embedded controller with an Espressif ESP32 SOC, integrated Wi-Fi and BT solution and a dual-core low-power Xtensa® 32-bit LX6 microprocessor with a main frequency up to 240MHz.

The controller has 16M FLASH onboard alongside an integrated 240x135 1.14" full-colour HD IPS display + physical keypad + rich peripherals, two sets of six expansion ports + low-power sleep/wakeup functions.

Users have multiple power supply options including USB Type-C, PWR485 and an 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.

We also stock the battery version of the M5Station.
