USB-C Cable Tests

Pin-to-pin connections for various USB-C cables

Testing Methodology

  1. Using Voltmeter, Red cable connected to VΩ (the very right hand side), Black cable connected to the fused 400mA.
  2. Red cable connected to pin A1 and black cable iterate through pins A1-A12 to B12-B1
  3. Repeat the process until Red cable reach B1 following A1-A12 to B12-B1
