Im about 1 week away from sending my first Arduino UNO based shield design to be manufactured.
I wanted to get a little input from the group.
As you can see from the attachments the main sensor is a 16x4 pixel thermal imager (MLX90620/21)
I have tested it on breadboard and the results are “ballpark” except for the 90621 which is ~10F off from the 90620
Im working with the coder who converted someone else’s code from a different library
I have also thrown in an I2C bus buffer and the pullups (for an external are set for a 20M cable. I have created a quick and dirty VB.net
based application to parse and display the data. There is also a 1wire local and remote bus with an extension connector.
Its a 4 layer board and 1 SDA and 1 SCL line do cross at layer 1 and layer 4, Im thinking that should not be a problem
because of the low speed … at least I think so …
Let me know your first impressions!
