Building a compact USB C to USB A adapter #USB #Design #PCB
Via the Facelesstech blog comes a compact USB C to USB A adaptor. We all want to be able to adapt one to the other, and this tiny design does that.
tl;dr – This might not seem useful to anyone else but me. At the side of my bed I have a USB C cable for charging my phone but on occasion I need to charge my “fitness tracker” or 3DS. I couldn’t find a adapter that went from female USB C to female USB A port so I decided to make my own. Join me below to see what I learn along the way.
In other projects I had been using Micro USB female ports to add a point to charge but I wanted to move with the times and add a USB C female port. The only ones I could find had the full set of pins for data and the like, Not very hand solderable. Luckily I found some 6 pin USB C female ports that did just power, Perfect for my needs. While looking at the data sheet for these ports I noticed they had CC1 and CC2 pins, What the hell are these when they are at home. After a bit of reading (mostly this page) I found out they are used by the electronically marked USB C cables, AKA the resistors the raspberry pi foundation left off the raspberry pi 4. With my project being a power receiving device It needed a 5.1k resistor pulled to GND on each of these pins.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
