Shared: November 29th 2014
Total Price: $28.45

For when you need to switch the positive side of your load (common cathode) instead of the negative side (common anode). Most FET shields use N-Channel MOSFETs which switch the ground connection, assuming the positive connection is always connected to power. This shield uses P-Channel MOSFETs w…

Offset Attenuator v1.0

2 layer board of 2.58 x 0.97 inches (65.4 x 24.7 mm)
Uploaded: September 15th 2014
Shared: November 20th 2014
Total Price: $12.50

A 4MHz offset attenuator for radio direction finding.

Mostly based off this design with a few modifications:

  • 3 position switch: Off, On (10db pad bypassed), and On with 10db pad.
  • Better filtering LPF from 4MHz oscilato…
