The Omzlo CANZERO is an Arduino-compatible board with builtin CANbus networking and designed to be connected to a NoCAN network, enabling you to create wired IoT applications for the home and garden.
If you don't know what NoCAN is, please check our presentation here or our successful Kickstarter campaign.
The Omzlo CANZERO is designed to act as an independent node in a NoCAN wired network. Each CANZERO node can be programmed independently and communicate with other nodes in the network, creating applications with multiple sensors and actuators spread over a distance of 300 meters (1000 feet) and more.
You can use the Arduino IDE to build your application and then upload the created firmware to your CANZERO node directly over the network.
At the heart of each CANZERO node is not one but two MCUs:
Both MCUs communicate with each other through SPI as well as through two additional GPIOs.
The Omzlo CANZERO shares the same mechanical footprint as the Arduino MKR Zero, measuring 61.5mm by 25mm (approx. 2.4" x 1"). As shown in the pinout diagram below, it also shares the same double row of 14-pin 2.54mm headers: most shields designed for the Arduino MKR Zero should work on the Omzlo CANZERO.
The CANZERO board integrates the following components:
The CANbus network runs by default at 125Kbps.
The bottom side of the board provides pin names and connection information.
As shown in the picture below, each CANZERO comes as:
You will need to solder the 14-pin female headers to the board before use. Soldering the headers is easy if you follow the instructions in our detailed installation tutorial.
To build a NoCAN network, you will also need a PiMaster HAT (also available on Tindie), a Raspberry Pi, a power supply and some cables/wires. These elements are not included with the CANZERO and need to be purchased separately.
This product is open-source / open-hardware.
We ship twice a week, typically on Tuesdays and Fridays.
Please note that we are seeing shipping delays due to the pandemic and related supply chain issues.
