I have a number of store bought cables of varying lengths I will test with. I will document those in my review. In addition, I will construct a maximum length CAT5 cable using crimping tools and connectors I have locally.   I have a basic pin out cable tester for CAT5 cables. I don’t have a Fluke network analyzer to do performance checks to prove out my cable assembly skills. I worked in cable plants for a number of years, so I consider my cable construction skills up to specificati ...
I'm doing a little white boarding for testing.   I would like to load the Pi power supply so that it draws the maximum current possible before I go to PoE. That maximum draw state becomes my test condition when operating from the PoE. This configuration would put the maximum strain on the PoE Hat under test. My thought is a maximum CAT5 cable length while under maximum draw is a good performance check for the unit.   Powering LED’s connected to all GPIO’s and taxing all C ...
After I received notice that my application was accepted, I confirmed the requirement for additional parts that would be needed in order to complete the RoadTest. A PoE power supply is not provided as part of the RoadTest. I do not have a PoE capable networking device. It was my assumption when I submitted the application I would need to purchase such a device if awarded the review. Now that I have confirmation it is off to Newark to make a purchase. I don’t have the PoE Hat unit to det ...
My response to the RoadTest application question “Have you written a blog on the Element14 community?” has always been no. I thought I would try and change that answer, by creating my first blog ever, using the Raspberry Pi4B (4GB) plus POE Hat RoadTest that was just awarded.   Before you become invested in this Blog, understand I am a writer by passion and a freelance writer by choice. Writing is both a curse and a joy for me. That doesn’t mean I get pleasure just droolin ...
For the main part of this roadtest, I wanted to look at the features of the TMC2300 that dealt with power consumption. The key one of these is coolstep but as we'll see there are a few other things to consider too. This article looks at the registers used when controlling the motor via the UART pin. However, it is also possible to use the TMCL protocol via the Landungsbrucke board Automatic Power saving When the board is configured for stand-alone mode and hence controlled with step and dir, t ...
