IoThing Digital – Digital I/O module with two high-power relays and two isolated AC or DC input channels

IoThing Digital is a professional digital I/O module with two high-power Omron G5Q-14 relays and two digital input channels (based on Texas Instruments ISO1211). It allows digital input of both DC and AC signals, so you are not limited in your choice of input voltage level. You can choose the voltage range yourself, for example, 60 VDC or 220 VAC or any other, up to 300 V. The design of this board also integrates a DC-DC converter and a slot for mikroBUS modules.

IoThing Digital can be used as an add-on module for popular SoMs such as Raspberry Pi, Arduino, Adafruit, Particle, SparkFun, Teensy boards and others. We will also be providing PCBs based on LPC824, SAMD21 and STM32F411 microcontrollers as add-on options during this campaign. As a bonus, IoThing Digital measures 65 mmx 56 mm and corresponds to the popular format of the Raspberry Pi 3A+, which greatly simplifies its use with the Raspberry Pi.

Perfect for Professionals and Hobbyists

IoThing Digital is perfect for engineers who are designing distributed / decentralized control systems, developers of modern IoT and IIoT (in which our module can be used as a basis for building compact embedded systems), and even amateur designers who automate everything – from thermometers in windows, to heating systems, up to the implementation of smart homes and smart farms.
