If your device is putted in metal box or WiFi signal is low, you can use PRODINo ESP32EX Ethernet with external antenna.

If you want to have control over other devices through Internet, mobile phone. You want to measure temperature, humidity or collect data from an environment - the PRODINo ESP32EX Ethernet is the device that you find. The device microprocessor include 2 cores with 32 bits architecture. The board can connect through WiFi, Ethernet and Bluetooth Low Energy protocols.

The PRODINo ESP32EX Ethernet has 4 relays. The 4 Relays are a solution for driving high power loads that cannot be controlled by digital IOs of microcontroller. Due to the current and voltage limits of the controller. Each relay provides 2 pole changeover contacts (NO and NC). Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve etc. Every relay includes a LED which indicate the on/off state.

The 4 digital inputs are optical isolated. This is helpful for connecting your device to a system with a different ground, different voltage or some noisy channel. This separate electrically (isolates) input channel from the controller input. Four LEDs indicate the On/Off state of each input.

LED indicators

 1 x RGB multi-functional led. You can use it for some statuses information 
 1 x Power 
 4 x Input On/Off for every optical isolated input
 4 X Relay On/Off for every relay output

How to use - you can see our tutorial and examples.
