Ethernet board has total 8 analog/digital inputs accessible via 4 connectors 2 inputs each and 5 relay outputs. It is based on ATMega 644 MCU and WIZnet W5500 ethernet chip.
Inputs have USB-A type connector male socket each having access to 2 ATMega IO analog IO pins and +5V power and ground. USB A-Type connector is very flexible. It allows to directly plug in PCB board with sensor adapter on it. Also, can be used for custom outputs.
Currently we have adapted DTH11 or DTH22 humidity and temperature sensors as well as popular DS18B20 digital temperature and NTC10K analog temperature sensors. Ziinode ethernet board have I2C connector for RTC and ATMega644 UART1 (Arduino Serial1) interface connector for SIM800 GSM module. For ATMega644 UART0 (Arduino Serial) there is an option to solder in the board RS485 line driver and terminal connector to access industrial devices.
