Product description

Unipi 1.1 Lite is an extension board for Raspberry Pi computer which allows it to function as a programmable logic controller for monitoring, control and regulation of automation systems. The Lite version is a smaller variant of the standard Unipi 1.1 board and represents the cheapest and simplest way to transform Raspberry Pi into a compact and powerful controller.

Note: The product does not contain the Raspberry Pi computer, software license or DIN rail holder. These components can be purchased either separately, or as parts of the Unipi 1.1 Lite complete set.

Package contents

  • Unipi 1.1 Lite board
  • quick start guide
  • 26 pin (2×13) flat cable to connect Unipi 1.1 to Raspberry Pi
  • 3× metal spacer 2M5 (20mm)
  • 3× screw 2M5

Basic Unipi 1.1 Lite features

  • 6× changeover relay (250V AC@5A / 24V DC/@5A)
  • 6× galvanically isolated digital inputs (7-24V DC, min. pulse length 5 ms)
  • 1× 1-Wire bus

Inputs & outputs

Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank) etc.

Relay outputs (RO) are primarily used for switching two-state devices with higher current draw such as lightbulbs, thermoelectric valve drives, water heaters, pumps etc.

Computing module

Unipi 1.1 Lite is powered by the Raspberry Pi computer. The board is compatible with the following Raspberry Pi models: 

  • Raspberry Pi Model B+
  • Raspberry Pi 2 Model B
  • Raspberry Pi 3 Model B
  • Raspberry Pi 3 Model B+
  • Raspberry Pi 4 Model B (all RAM variants)

Note: Unipi 1.1 Lite cannot function without Raspberry Pi

Communication interfaces

Unipi 1.1 Lite features a single 1-Wire bus for reading data from various 1-Wire sensors (thermometers, humidity meters, light intensity meters etc.). The bus usually utilizes 2-3 conductors and its maximum length can reach up to 200 meters. Up to 15 sensors can be connected to a single bus. 

Software options

Due to the software openness of Unipi controllers the customer has a wide array of software solutions to choose from and is not limited to a single software.

The main supported platform for programming of Unipi controllers is the Mervis system. Mervis is developed according to the IEC 61131-3 standard for PLC programming and consists of SCADA interface for remote control and monitoring, comprehensible development interface, integrated HMI editor and online/on-premise database for storing data and historical analysis of the controlled technology's operation.

Aside from Mervis, Unipi controllers are also compatible with a wide variety of both commercial and open-source platforms. It is also possible to choose from a large number of open-source platforms, use EVOK API (Websocket, REST,...) or Modbus TCP, or implement your code in any programming language. For an overview of more compatible commercial solutions please visit Other software overview.
