ESP32-based controller with 4-20mA analog inputs, and GSM communication including micro SD, ethernet and RTC. USB Programmable Controller with multiple connectivity channels. Ideal for an IoT gateway ...

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

ESP32-based controller with 4-20mA analog inputs, and LTE communication including micro SD, ethernet, and RTC. USB Programmable Controller with multiple connectivity channels. Ideal for an IoT gateway ...

You’ll need additional modules (~$200 each) for digital and analog IO. On the other side, Raspi, Arduino and other toys have some IO onboard. But (I hope :) no one will ever use them for ...

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...
