| 15 | These captures were made using different prototypes of the 'usb-c-grok', which | |
| 16 | is an FX2 based device designed to capture USB Configuration Channel traffic. | |
| 17 | ||
| 18 | I made all captures with PulseView, with the samplerate set to 4 MHz, except | |
| 19 | when noted otherwise. | |

| 27 | - Can be configured for 5/9/12/15/20V, or "highest possible" or | |
| 28 | "all in sequence" | |
| 29 | - Set to 9V, because I used it to upgrade a 9.6V toy car | |

| 60 | This supply lies. It says 65W on the box and device but advertises only 60W. | |
| 61 | The sink is a module available from aliexpress or ebay which I configured to | |
| 62 | request 9V. | |

| 68 | The same module as before, now connected to the Anker powerbank, and configured | |
| 69 | to request all the voltages sequentially, with 1800ms between each one. This | |
| 70 | was captured at 6 MHz because at 4 MHz it had some issues with decoding packets | |
| 71 | from the ZY12PDS module, but only at some voltages. |
