A week or two back somebody was commenting on a chip that does voice compression.? A quick search on AliExpress found a module that uses said chip for a few dollars, so I bought a couple for my Bitx40s.
I figured these boards were a bit bigger!? The coin is about the size of an American quarter.
Any ideas for how to remove the tiny resistors R1 and R2 (about 1mm in length and .5mm wide) so that I can use potentiometers instead? ?
These modules are very tiny indeed!? There will be no trouble finding room for them in any enclosure.? I will report on how they work in a few days time!
