Communication


  • WiFi
  • Bluetooth low energy
  • Ethernet
  • LoRa WAN
  • RS485

Relay outputs


The ProDino ESP32 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.

Optical isolated inputs


The 4 digital inputs are optical isolated. This is helpful for connecting your ProDino ESP32 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. How do we use them?

LE​​​​D indicators


ProDino ESP32 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

RS485


Thanks that the ProDino ESP32 board owns a RS485, now you will be able to have a communication port for your RS485 devices! It will allow up to 32 devices to communicate through the same data line over a cable length of up to 1200m/4000ft. It is and the ultimate expansion that allows your board to connect to almost every legacy industrial system using serial connectivity such as industrial PLCs, controllers, drives and HMIs. 

The RS485 can be use to turn old industrial systems like industrial machinery, heating systems and conveyors into new IoT devices. It supports high speed 500 Kbps in a short distance.

GROVE connector


The ProDino ESP32 board contains one GROVE Digital connector. The Grove System simplifies traditional electronics it consists of a base platform and various modules with standardised connectors. Each Grove module addresses a range of functions such as simple LEDs, buttons, switches to complex servo control, etc. With the combination with Grove modules, the project possibilities are endless!
