Ziinode ethernet board is has total 8 analog/digital inputs accessible vai 4 connectors 2 inputs each and 5 relay outputs. It is based on ATMEGA644PA-AU MCU and WIZnet W5500 ethernet chip.
Inputs has USB-A type connector male socket each having access to 2 ATMEGA644PA-AU analog IO pins (PA0-PA7) 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 ATMEGA644PA-AU UART1 (arduino Serial1) interface connector for SIM800 GSM module. For ATMEGA644PA-AU UART0 (Arduino Serial) there is option to solder in the board RS485 line driver and terminal connector to access industrial devices.
