[OSHPark] PWM Audio Buffer Boards (SMD and Through Hole)

Post by **Helder** » Sat Jun 04, 2016 7:53 am

So after getting positive feedback from a tester on these boards I've decided to make them public to anyone. There are 2 versions I've made so you can use which ever you feel your skills can handle. The SMD version uses 0805 size capacitors and resistors, the through hole uses standard resistors and 5-6mm radial electrolytic capacitors (any 10uf 10v will fit).

OSHPark sells them in lots of 3 unpopulated of course

Unfortunately I can't test it now and I won't be able to for weeks because I'm at the very beginning of my project.

But it looks good !

Why haven't you put an amplifier and a 3.5 Jack connector on it ?

Awesome! This will make PWM audio much easier for some folks I'm sure.

That's the future plan but this setup is based on Brian's tests and just this seemed to work for him. This is part of a bigger project but I need to know how well this works by itself though.

@wermy I can send you one if you'd like to be my guinea pig

I wouldn't say no to that!

If it's here in time I could show how it works in the next guide (hoping to have that one up towards the end of next week).
