    Help with USB-C to UART schematic using FT230X and STM32

    Hi all, I am trying to add a USB-C socket on my PCB that I would like to use for data transfer only. I currently have a simple UART molex connection, but I would like to upgrade it to USB-C in my next iteration of my PCB :) I am using the FT230X to convert it to UART as I want to use DMA...

    2 Power sources, 1 load, and possibly daisy chaining power

    Hi, I'm pretty new to all of this, so please let me know if something doesn't make sense. I am building display units with LEDs in them, powered by a 5v USB C to make it easy to disconnect and cable manage. I would like to put a USB C port on the left side of the unit, as well as another USB C...

    Device Powering with the USB Type C

    Hi Every One , There is scenario where I have to use the USB C type adapter for my application device ( Microcontroller and Servo motor ) which draw a 5V and 1.8 A power max. I tried connecting the USB C type adapter but I observed below points a) I'm only getting the 480mA current through...

    Looking for a bypass circuit for usb-c

    Hi all. I'm putting together a fairly simple project, imstalling a bluetooth amp in the shell of an old boonbox to power the speakers. For power delivery, I intend to use a lithium ion powerbank capable of supplying 20v via USB-C and a USB PD spoofer. The only problem is, the powerbank also...

    USB-C input: using USB-C chargers/cables as well as micro-USB chargers/cables

    Hi! I want to power an Arduino project with external, regulated 5V (say up to 1.5A). For versatility, I would like it to have a USB-C type input connector so I can grab any 5V charger I have laying around at the time of using it that can deliver at least 1.5A@5V. I read that connecting 5.1k...

    Where to buy cable suitable for USB connections.

    USB was intended to be a universal data connection protocol and hardware standard, and has been passably successful in so becoming. However, the more I see of USB C the less I like it, especially solely as a power connection for SBCs such as Rpi. It's like using a steam-shovel to hammer a nail...

    Converting Thunderbolt 2 to USB C

    Hi, First post on this forum, so forgive if i'm not familiar with some of the do's and dont's. I have a Thunderbolt 2 to VGA connector which I wanted to convert to USB type C. I've very crassly sliced the connector open without thinking, which has led me to discover that both these structures...

    Custom standalone atmega32u4 pcb showing up as unknown device

    Hi there, I am having issues with a standalone atmega32u4 project i've been working on and was hoping someone would be able to help :) I have designed a pcb that uses the atmega32u4 to recreate the arduino leonardo. I have been able to successfully burn the Arduino bootloader onto the chip...

    Need a hand understanding a section on datasheet example schematic (CYPD3177 USB-C Controller)

    Hi all. I'm currently designing a circuit using a CYPD3177 USB Type C Controller to change the output voltage of a USB C power supply with power delivery support. I was looking at the example schematic in the datasheet to understand how the chip is used but I'm struggling to get my head around...
