Beaster AD9851 DDS Signal Generator Module 2 Sin Wave(0-70MHz) and 2 Square Wave(0-1MHz) with 30MHZ Crystal Oscillator

Owning a decent function Waveform generator is sometimes pretty much mandatory or for an electronics tinkerer to for example evaluate filter circuits or stress test a small MOSFET circuit the one I've been using is the Siglent SDG2082X Which works like a charm and offers tons of awesome additional features The only problem is that electronics beginners probably do not want to spend 600 euro on such a piece of equipment Thankfully though, cheaper function generators do exist like this AE20125 which you can get for around 70 euro and While this generator does create sine square and triangle waves up to a frequency of partly 10 megahertz I'm not satisfied with its maximum output level between - and +5 volts So in this episode of DIY or Buy, let's see whether we can make our own decent function/ waveform generator or whether we should stick to the buy version instead Let's get started...
