What is it?

Wifi <-> RS485 <-> LoRa device has a combination of Wifi, LoRa technology bridge with RS485 for industrial application for remote monitoring and control in the Industrial 4.0 environment. Ideally suitable application remote monitoring and controlling ideally for industrial application, which can minimize wiring along the floor or roof. This board has Wifi module based on ESP32, STM microcontroller and DRF176G LoRa module interfaced through SPI communication and the board is designed to support for LoRa WAN protocol. The STM microcontroller and ESP32 used is this board is Arduino IDE compatible, so that users need not to worry about external programmer and board is designed such that, it can be directly connected to computer USB to program it just by using mobile data cable, and not required to use any external hardware to program both for STM controller or WiFi module. The device has an option to set Device ID for RS485 application by selecting Dipswitches on board, which also be taken care while developing application-specific code for the device.

The new device will come with basic test code for Wifi, RS485 and LoRa for testing purpose only, not for any application. The application specific code has to be developed by users. ARMtronix can develop any application specific code on specific requirement basis only. Please mail if any such specific requirements at sales@armtronix.in.

Why did you make it?

Many people have energy meters or other devices which have Rs485 communication. This device can interface with such devices to make them IoT enabled system
