Adafruit Pro Trinket 5V 16MHz ATmega328P Board
The Adafruit Pro Trinket 5V is a compact ATmega328P-based development board, ideal for shrinking Arduino UNO prototypes. It features a 16MHz clock, 28K flash, and onboard USB bootloading via MicroUSB or FTDI cable.
Features
- ATmega328P microcontroller (QFN package) for full Arduino UNO compatibility in a tiny footprint.
- Onboard USB bootloader with MicroUSB port and FTDI header for flexible programming.
- Integrated 5V regulator with 150mA output, 16V max input, and reverse-polarity protection.
- 18 GPIO pins and 2 extra analog inputs for expanded project connectivity.
- Ultra-compact PCB measuring 1.5″ x 0.7″ for space-constrained embedded applications.

The Adafruit Pro Trinket 5V 16MHz serves as a powerful, miniaturized successor to the classic Trinket, built around the familiar ATmega328P core. It delivers the processing muscle of an Arduino UNO—including 28K of program flash and 2K of SRAM—within a board measuring just 1.5 by 0.7 inches. This makes it an optimal choice for transitioning from a breadboard prototype to a finalized, compact embedded system.
Engineered for robust field deployment, the board incorporates a high-performance 5V linear regulator capable of accepting inputs up to 16V DC, providing 150mA of clean power to external sensors and peripherals. The inclusion of both a MicroUSB port for direct USB programming and a breakout header for FTDI serial programming offers developers maximum flexibility in firmware uploads and serial communication, supporting the Optiboot bootloader for rapid iteration.
