I am clearing 100 Pulse Width Modulation Frequency Modules from my site. If anyone is interesting have a look at them on my site www.alterntech.co.uk or www.alterntech.com/products .They are only $7 each fully built…. Yes, I am virtually giving them away at the material costs to me to clear them, Pay $15 and I will boxed it up for you to use straight away. Very simple to modify.... Thanks Guys..
