UA Micro Node V1.0
Last updated
Last updated
The UA CAN node allows you to create production grade PCBs without needing to worry about the complicated bit. Put the board to board connector on your project, wire in a sensor, a connector and now you have a CAN enabled project.
We do QA and software upload, meaning you just have to screw the board down to your project.

The can node is designed to mounted with screws for maximum mechanical security, whilst still being replaceable. We recommend using SMT standoffs to minimise build time and allow the node to be changed without access to the bottom of the board.
We've selected a standoff from mouser which has plenty of stock, however other 1.5mm, M2 standoffs will also be applicable.
the drawing shows:
This should be used with an M2 4mm length bolt (2x PCB thickness + standoff = ~4.5mm)
We support AP Periph based firmware's for our CAN node. Our node is compatible with the matek L431 firmwares. We may release our own customised firmwares in future.
We can flash a custom firmware on your request.

Based on environmental ratings for the components and board manufacturer statements. Not a tested figure by Unmanned Avionics.
The boards can be conformally coated on request
Temperature > -20 °C to 85 °C ambient temperature
We test every board we dispatch. Our process is:
Mount the node to a test carrier
Upload testing firmware
Our software checks every pin is functioning as expected
Upload customer firmware
Check node status can be seen through CAN interface (if applicable)
Package for dispatch
The mating connector required for your design is the Hirose DF37NC(1.5)-40DS-0.4V(51)
