![]() ![]() The CC pins contain pull-up or pull-down resistors so that the port configuration can be detected to figure out whether it is a down-stream facing port or upstream-facing port, cable detection and current capability advertisement.įor our case of microUSB USB slave that just needs to draw current, the CC1 and CC2 pins must have a 5.1 Kohm pull-down resistor each.Īn example of a connector with VBUS, GND and CBS pins exposed is shown here. You cannot leave them floating around, or the USB host may not put out the power you need via the USB VBUS pin. The CC pins are used for configuration detection purposes. What do you do with the CC1 and CC2 pins? Usb Cable 2.0 To Type C Usb 3.1 Cable Type-c 3.0 Adapter Fast Charger Usb-c Data Sync - Buy Micro Usb Type C. Those that do not expose the CC pins just have internal resistors inside the connector to set the proper configuration. For all other applications, the connector will function like any other power jack and the charging will be governed by the adapter/charging circuit. In fact, the CC pins are compulsory to implement on ALL connectors. Backward compatible to other USB connectors using converter cables or adaptors Distinctive design on the back of the receptacle shell for industry leading EMI. The signaling rate of a USB 2.0 is up to 480 Mbit/sec, while USB 3.0 can go up to 5 Gbit/ sec, which is equal to 500Mb/s. USBs with a bandwidth near 12 Mbit per second or 1.5MB per second are high speed, while those ranging around 1.5Mbit are low-speed. ![]() Many connectors will usually expose CC pins of the connector too. The working of the USB depends on the bandwidth. There are not a ton a USB-C connectors in the market that just bring out the power pins for you. ![]()
