KFDShield™ – No Soldered Headers


The KFDShield™, but with the headers included loose instead of being soldered on the board.

Out of stock



This is the same as the KFDShield™, but includes the PTH headers separately rather than soldered on the board.

The KFDshield™ is an open-source Key Fill Device compatible with the P25/TIA-102 AACD standard. In short, it is a shield that transforms your Arduino or other footprint-compatible microcontroller into a device capable of performing keyloading and other key maintenance operations on compliant Project 25 digital radios. The KFDShield™ comes with both a 3.5mm TRS jack (aka a headphone jack) and a Euroblock style detachable screw terminal connector for the keyfill output. With both connectors it gives the ability to have both more polished cables and the ability to hook up whatever you need at a given moment. Note that these are wired in parallel and weird things can happen if you plug in two radios at once – so don’t try it. Additionally on the KFDShield™ are some buttons and a footprint for an OLED screen – soon to be carried in the store. This allows for future standalone applications so you can perform certain keyfill operation in the field without the need for a computer. Or, if an OLED isn’t up your alley, you can ditch it and use the prototyping area underneath it to build a custom circuit.
