CANADUINO MEGA328 PLC-100 V2 SMD is a ready assembled and tested variant of our new version V2.

It provides the same features like the DIY soldering kit (SKU 26442) but does not require any soldering.

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.

A few use cases:

1. Closing the garage door after the car is parked in position and no movement is recorded for 2 minutes.
2. Starting background music with the garden watering 30 minutes after sunset when soil moisture is <20%.
3. Injecting water when the humidity in your smoker drops <60% but the temperature is >70C.

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)

Advantages over the old version:

– Power supply 12*-24V DC instead of 12V DC only
– High-efficiency DC-DC voltage controller instead of LDO and Zener diodes
– Analog outputs provide full 0-10V swing with less PWM ripple
– Better protected digital inputs with wider voltage range
– I2C connector “STEMMA” (5V) for devices like sensors or displays

The module is assembled and only requires the coin cell battery and an Arduino Nano to be ready for your program development.

*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.
