CANADUINO MEGA328 PLC-100 V2 SMD DIY Kit is a pre-assembled version of our V2 SMD. The PCB comes with all SMD parts factory assembled, and through-hole parts (headers, screw terminals and relays) need to be soldered by you.

It provides the same features like the DIY soldering kit (SKU 26442) but requires less soldering due to the pre-assembled SMD board.

The CANADUINO MEGA328 PLC-100 V2 SMD is a fully fitted, tiny Programmable Logic Controller for Arduino Nano V3 (sold separately) with a footprint of only 100 x 80mm. It offers a very affordable opportunity to add programmable controls to different kinds of applications.

PLC-100 V2 is compatible with Arduino Nano V3 (Atmega328P) 5V modules, and can be programmed using Arduino IDE, Open-PLC, different ladder programming tools, or code-free applications like Visuino from Mitov.

PLC-100 V2 fits just any budget and delivers more power and versatility than many other control devices.

The new version V2 has a STEMMA-compatible I2C connector (5V logic level) on board which allows for easy expansion with sensors, displays, or any other I2C compatible devices.

A real-time-clock chip DS1307 supports you with scheduled and timer controlled applications.

Basic features:

– Power supply 12*-24V DC, 0.5A – 4 analog 0-10V inputs (10mV res.) – 4 analog 0-10V outputs (2.5mV res.) – 4 digital inputs 3.3-24V – 6 digital 250V/5A relay outputs – I2C bus (5V) with STEMMA connector for external sensors, displays etc. – DS1307 RTC with battery backup (CR1220 coin cell included)

The module is pre-assembled and only requires you to add headers for the Nano, the screw terminals, and the relays (everything is included). An Arduino Nano is required for operation (available as option).

Please note the important information about the I2C port in the image gallery!

*At 12V supply voltage, the maximum analog output voltage is limited to about 9.6V, which is still within the allowed tolerance for 0-10V systems. To achieve full 10V analog output voltage, the supply voltage must be at least 12.2V DC.
