NEW PRODUCTS – USB to 2.1mm DC Booster Cable – 9V / 12V


These cables are kinda fascinating – they have an integrated boost converter, so you can plug them into any USB port (from a computer, battery pack, etc) and they will give you a higher DC voltage! It’s a handy way to power 9V and 12V powered devices with a 2.1mm DC barrel jack from a USB port. If you just need a passthough cable, here’s one for 5VDC.

These are rated at 500mA output, but you can go a little higher, we pulled 700mA and we got a little voltage droop but it worked fine. Probably best not to draw 700mA continuously though!

Here’s our measurements for various current draws when we set our bench supply to provide a steady 5V voltage

  • 50mA (9.0V output), 100mA, 90% efficiency
  • 100ma (8.95), 205mA in, 87% efficiency
  • 200ma (8.9V): 410mA in, 86% efficiency
  • 300ma (8.8V): 620mA in, 85% efficiency
  • 500ma (8.8V): 1060mA in, 83% efficiency
  • 700ma (8.8V): 1550mA in, 80% efficiency

So, overall there’s a 90% efficiency at low current draw that drops do about 80% at high current use. There’s also a 3 mA quiescent current. Note that often times the USB port voltage can droop too, and in addition you may have power losses with any thin or low quality cables with high resistivity!

Here’s our measurements for various current draws when we set our bench supply to provide a steady 5V voltage

  • 50mA (12.4V output), 150mA, 83% efficiency
  • 100ma (12.4V), 290mA in, 86% efficiency
  • 200ma (12.3V): 570mA in, 86% efficiency
  • 300ma (12.2V): 870mA in, 84% efficiency
  • 500ma (12.1V): 1500mA in, 81% efficiency
  • 700ma (11.4V): 2140mA in, 75% efficiency

So, overall there’s a 85% efficiency at low current draw that drops do about 80% at high current use. There’s also a 3 mA quiescent current. Note that often times the USB port voltage can droop too, and in addition you may have power losses with any thin or low quality cables with high resistivity!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
