## Description

Note: The Pro Trinket's bit-bang USB technique is a legacy approach that may not work reliably with modern operating systems. For new projects, consider an ItsyBitsy or Metro Mini board with native USB support at a comparable price. The Adafruit Pro Trinket 5V is a compact ATmega328P-based microcontroller board that packs Arduino UNO-level capability into a 1.5" × 0.7" form factor. Running at the same 5V and 16 MHz as the UNO, it's compatible with 99% of Arduino sketches right out of the box. It's programmable via the Arduino IDE using the on-board USB bootloader or an FTDI serial connection. Key Features ATmega328P Processor – Same chip as the Arduino UNO, running at 5V and 16 MHz 18 GPIO Pins – Including 2 extra analogue inputs beyond standard Trinket (pins 2 and 7 reserved for USB) 28 KB Flash / 2 KB RAM – 4 KB used by bootloader, 28,672 bytes available for sketches Micro-USB Connector – For power and code uploads via USBtinyISP-compatible bootloader FTDI Header – Alternative serial programming and debugging via FTDI cable 5V Regulator – 150 mA output, up to 16V input, with reverse-polarity and thermal protection Auto Power Switching – Automatically switches between USB and external battery power Power and Status LEDs – Green power LED and red LED on pin 13 Reset Button – Enter bootloader or restart your program Mounting Holes – For secure physical installation Limitations Pins 2 and 7 are reserved for USB and unavailable for general use No Serial-to-USB chip — use an FTDI cable for serial monitor access Cannot plug Arduino shields directly onto the board 5V regulator provides 150 mA (not the 800 mA of a full UNO) Also Consider Pro Trinket 3V – Same board running at 3.3V / 12 MHz for lower-voltage projects Ideal For Compact versions of Arduino UNO projects Wearable electronics and small-form-factor builds Portable and battery-powered projects Prototyping before moving to a final embedded design Package Contents 1× Adafruit Pro Trinket 5V (assembled, without headers) Resources Introducing Pro Trinket Tutorial
