RS485 industrial device connection
Designed for connecting RS485 field devices such as sensors, meters, PLC-related modules, controllers, and industrial data terminals.
MQTT data upload over Wi-Fi
ESP wireless module area for converting RS485 data into MQTT messages and uploading them to local brokers, dashboards, cloud platforms, or industrial IoT systems.
USB-C power, firmware, and debugging
USB-C connector can be used for power input, firmware download, serial debugging, MQTT configuration, and development workflow support.
Industrial wiring terminal blocks
Green terminal blocks make wiring easier for RS485 bus signals, power input, and field installation experiments.
Power regulation for field use
On-board power conversion area supports stable operation for RS485 communication, Wi-Fi transmission, and industrial data upload testing.
Open hardware and firmware files
Recommended open files include schematic, PCB source, BOM, Gerber, CPL, MQTT firmware examples, RS485 polling examples, and test notes.
