Introduction

WireLa03 is a 3ch Wi-Fi relay board with many smart on-board peripherals. It can fit in a din-rail enclosure and it is designed as a practical, robust and safe solution for diy-iot/smart-home applications

WiRela devices can be considered a platform for diy IoT and Home-Automation enthusiasts in a similar way that Arduino boards are a platform for a general DIY embedded makers.

Here is an image of a PCB with the legend for a better idea of what is featured on-board:

Product is fully Arduino supported and it has FTDI pins breakout. In order to illustrate on-board peripherals better, here is a equivalent, Arduino-style, fritzing block diagram:

Features:

• Universal high-quality on-board AC/DC converter with fuse protection for powering the board
• Terminal block connectors for external sensors (analog such as PTC,NTC,LDR and digital such as wired DS18B20)
• SI7021 temperature and humidity sensor on-board
• DHT22/DS18B20 breakout at the PCB edge
• RFM69HW wireless radio support in the ISM band (for wireless sensors/keyfobs)
• Atsha204A Crypto IC onboard for authentication security and session keys
• RTC for timer/thermostat/schedule functionality
