XR2206 DIY Function Generator Kit Build & Review

If you're looking for a DIY function generator kit and wondering how those low cost, three dial ones with the popular XR2206 chip go together and work; here I'm building & reviewing one of the most popular little signal function generator kits on the market.

For around $10 USD or less, the value is good considering if you were to source the components yourself, get the PCB made along with the case, it would easily cost double that amount. The instructions are good & easy to follow with a low component count making it a great first PCB soldering project for beginner hobbyists.

These DIY function generator kits do exactly what they claim, producing a square waveform in combination with a sine or triangle wave, ranging from just under 1Hz to over 1 MHz. The waveforms degrade significantly at the extreme low and high ends of that frequency range, but are decent otherwise. Operation is easy with a simple amplitude/voltage knob, with fine & coarse frequency knobs used in conjunction with a pin jumper to select the 5 frequency ranges.

A great little low cost signal generator to build & play with if you just got your first oscilloscope or want to create some simple sound generation signals.
