Control Panel Info&Ordering

page modified June 17, 2020

The control panel is a project by Larry WN8P with guidance from Tadd, KA2DEW.



The control panel is 1.25" x 5.25". It fits perfectly under the Raspberry PI in a Fin Base-Box.

Specifications may change without notice.
Do not use this device in any situation where the loss of life or property would be the result of the device misbehaving or failing. If you go beyond this rule, you are self-certifying this device. This device is built by hobbyists for a hobby project. We do not certify that this design, or any particular unit, is sound. No UL or CE listing or testing! Use it at your own risk.

Control Panel is coming soon


Here's the control panel schematic. Click to load the PDF.

Note that the LED current-limit-resistor values will not match the schematic. The resistors selected for the bill-of-materials were selected to balance the LED brightness.

The ribbon cable connects to the Raspberry PI expansion connector on pins 15 through 24. A 2x5 IDC connector is plugged into that connector and will require the removal of pins 13, 14, 25, 26 to fit. Alternatively, an Adafruit stacking header may be added, permitting the header to be masacred instead of the Raspberry PI header. Experienced network advocates have noted that the new version of Raspberry PIs have been coming so fast and with features rending the old models antique by comparison, that recycling a Raspberry PI for another project is not necessary. Furthermore, projects which use the expansion connector are not common, so destructive modification of the Raspberry PI is reasonable to save $3 that it would cost for an expansion adapter. If you WANT the stacking header, order it through DigiKey when you get your parts.

9 of these are assembled and 2 are deployed to nodes. I made a video and that's here:
