But what if the solution was already there, with your MCU and enabled you to have greater control over these voltages? Well, with the help of some USB Type-C magic and the new Arduino MCUs, you can! But, if a microcontroller can’t deliver, then something else will. The PD Micro is an innocent-looking Arduino at first, friendly enough for you to place it into a breadboard and start tinkering. But when you get to the nitty-gritty, you are going to find much more, something rather unique on this type of board.

Through the use of a 30 V P-channel MOSFET load switch controlled by an Arduino MCU and a library developed by Ryan Ma, you can safely enjoy USB Type-C’s promising USB PD (Power Delivery), which allows you to negotiate power of up to 100 W. The PD Micro adds some extra protection to your circuitry by only delivering the power required is ready and meets the target voltage and current levels. The first step is to download the latest version of the Adafruit Fritzing Library from GitHub The easiest way to do that is to click that big nice button up there, otherwise you can also go to the GitHub repository and manually download or clone. #Fritzing power supply download#Ī really cool thing about it is that you can get away with not using another board.

I / O: 9x 10-bit ADC pins, 12x Digital I / O’s, 5x GND pins, 3x VBUS pins (USB Power Delivery) and 1x 5V pin.ĪTmega32U4 MCU, clocked at 16 MHz (Arduino Pro Micro).Regarding specifications, you have at your disposal: As you have already an Arduino at your disposal, all you might need for your project is already there.

Power: USB PD grants negotiable 5 V, 9 V, 12 V, 15 V or 20 V at a maximum of 5 A (100 W at 20 V).

PD status LED’s: Tx / Rx activity, 5x for Power Delivery voltage level and 5x for current level.

DC-DC converter for efficient 5 V 0.5 A output A such power supply must be exact same voltage as regulator pots out.

Size: 1.6 x 0.7 inches (plus 0.3 inches for the power connector pins).Īlternativ may be to cut the trace bringing 5V to the.

When it comes to the control of USB Power Delivery, this device has the unique feature of allowing you to control it with an Arduino.

There are other boards that do this job, but I doubt you will find something nearly as convenient to use and with all the functionalities this one has.

Lastly, this is still a CrowdSupply project, which already smashed its goal, while there are still some days left.
