Unleash Your Creativity with the Adafruit Pro Trinket 5V 16MHz: A Powerful and Versatile Microcontroller for Your DIY Electronics Projects

Introducing the Adafruit Pro Trinket 5V 16MHz (1 Piece) ATmega328P onboard chip in QFN package. This small but powerful microcontroller board is perfect for DIY projects and applications that require a compact and reliable control system. With its 16MHz clock rate and 28K FLASH available, the Adafruit Pro Trinket is capable of handling a wide range of tasks, making it a versatile and practical tool for hobbyists, makers, and engineers alike.


The Adafruit Pro Trinket features a USB bootloader with a nice LED indicator and headers for an FTDI port for reprogramming. This means that you can easily reprogram the board using a USB cable, and the LED indicator lets you know when the process is complete. With its on-board 5.0V power regulator with 150mA output capability and ultra-low dropout, up to 16V input, reverse-polarity protection, thermal and current-limit protection, the Adafruit Pro Trinket is also very safe and reliable.


In this article, we’ll take a closer look at the Adafruit Pro Trinket and its features, as well as explore some of the possible applications for this powerful microcontroller board. We’ll also provide some tips and tricks for using the Adafruit Pro Trinket in your own projects, and show you how to get started with programming the board.
The Features of the Adafruit Pro Trinket

The Adafruit Pro Trinket is a compact and powerful microcontroller board that packs a lot of features into a small package. Here are some of the key features of the board:

ATmega328P Onboard Chip in QFN Package

The Adafruit Pro Trinket features an ATmega328P onboard chip in a QFN package. This chip is a powerful microcontroller that is capable of handling a wide range of tasks, from controlling motors and sensors to communicating with other devices.

16MHz Clock Rate

With its 16MHz clock rate, the Adafruit Pro Trinket is able to process data quickly and efficiently, making it ideal for applications that require high-speed processing.
28K FLASH Available

The Adafruit Pro Trinket features 28K of FLASH memory, which is enough for most applications. This memory can be used to store code and data, allowing the board to perform complex tasks.



USB Bootloader with a Nice LED Indicator

The USB bootloader on the Adafruit Pro Trinket makes it easy to reprogram the board using a USB cable. The LED indicator lets you know when the board is in programming mode, making it easy to monitor the programming process.

Headers for an FTDI Port for Reprogramming

In addition to the USB bootloader, the Adafruit Pro Trinket also features headers for an FTDI port, which can be used for reprogramming the board using an external programmer.

On-Board 5.0V Power Regulator with 150mA Output Capability

The on-board 5.0V power regulator on the Adafruit Pro Trinket provides a stable and reliable source of power for the board, with a 150mA output capability.

Ultra-Low Dropout, Up to 16V Input

The Adafruit Pro Trinket also features an ultra-low dropout, which allows it to operate at voltages as low as 5V, and up to 16V input.

Reverse-Polarity Protection

The Adafruit Pro Trinket also features reverse-polarity protection, which helps protect the board from damage if the power supply is connected incorrectly.

Comparison to Competitor

Now that we have explored the features of the Adafruit Pro Trinket 5V 16MHz, let’s compare it to a similar product on the market. The product we will be comparing it to is the Arduino Pro Mini 328 – 5V/16MHz.

While the Arduino Pro Mini 328 is a popular microcontroller, it falls short in several areas when compared to the Adafruit Pro Trinket 5V 16MHz. Firstly, it lacks the USB bootloader and LED indicator, which makes it more difficult to reprogram and modify. Additionally, it only has 16K of FLASH available, which means it may not have enough memory for larger projects.
