Product description
Adafruit Pro Trinket 5 V is Adafruit's version of the Pro Mini. A compact development board based on the ATmega328P microcontroller, the same microcontroller used in the Arduino UNO. The board operates at a clock frequency of 16 MHz and a 5 V logic level and is an alternative to the Arduino UNO for projects where space is limited.
Pro Trinket has 18 GPIO pins, 2 KB of SRAM and approximately 28 KB of flash memory available for user programs. The board can be programmed using the Arduino IDE via the built-in USB bootloader and micro-USB connection. It also supports Optiboot and programming via an external FTDI adapter.
The board is compatible with most Arduino programs, but some limitations apply. GPIO 2 and 7 are reserved for USB, and the board lacks a built-in USB-to-serial converter. The USB connection is therefore used only for programming and power supply. An external FTDI adapter is required for serial communication.
Pro Trinket features a built-in 5 V voltage regulator, automatic switching between USB and external power supply, and protection against reverse polarity, overcurrent and overheating. The board also features a reset button, mounting holes and LED indicators.
