| USB C vs type B micro for a new design. |
| (1/10) > >> |
| Fflint:
I'm designing a device I'd like to keep using 10 maybe 20 years from now. This thing is not going to be unplugged or moved often. If it was there would be no hope at all of achieving this lifetime. I need a capable uC inside with a USB interface to talk to a PC. I decided to use rp2040. This will be in form of a rpi pico with a USB B Micro connector or tiny2040 which is the same chip but with USB C. I have to choose based on the connector because other benefits/diosadvantages cancel out. Now USB C is a clear personal preference for me. The connector seems a lot more robust, but it may very well be just a perception. The standard hasn't been around long enough for me to say for sure: yeah, USB C will last longer. I have drawers full of useless USB B Micro devices the only failure in them being the connector. I have my own share of frustration with that connector, but it is useful to remember it first entered the market in 2007. That is 18 years... A very long time for an electronic device. And likewise I have some devices from that era that continue to work fine. So I'm not sure which one to choose and I decided to post here. Which would you choose and why? Do you have any data backing it up one way or the other? Please note I have to choose one of these two existing devices. I have no way to use a more robust version of a connector. It is what ot is if I choose one or the other device. Also, this device is just for me. It will not be sold. I don't have to consider other people's preferences. What would you do? |

Have in mind that in USB-micro you have 5 pin contacts and in USB-C 24 pin contacts. A month ago I have read (at Usenet electronic group) that someone found thrown away laptop and the only failure was USB-C. Laptop didn't had any other way to charge its battery. Now someone writing it is the happy owner of a relatively new laptop (older ones had normal round power connectors). |

Anything can be broken with enough abuse, but USB-C connectors have proven robust, more so than micro-USB IME. It also provides way more functionality; multi-voltage, up to 240W power capability, video, audio etc.. |

Definitely type C if those are your two choices. |
