SPIDER Automation Adafruit Pro Trinket 5V 16MHz | ATtiny85 Microcontroller & USB Bootloader | For Compact Embedded Applications
Description
The Adafruit Pro Trinket 5V is a compact ATtiny85-based microcontroller development board designed for embedded applications where board size, simple programming and essential I/O are more important than the extensive peripheral set of a larger development board. It provides a small Arduino-compatible platform for integrating control logic into space-constrained electronic systems.
The onboard ATtiny85 provides 8KB Flash, 512 bytes SRAM and 512 bytes EEPROM, together with 5 available I/O pins that can be used for digital, analog and PWM functions. The internal oscillator operates at 8MHz and can be configured through software for 16MHz operation on the 5V version.
A built-in USB bootloader allows the board to be connected to a computer for firmware uploading through its Mini USB interface. The bootloader supports programming workflows using Arduino IDE with the required configuration and AVRDUDE with the appropriate configuration adjustments.
This is the 5V version of the Trinket family. It is intended for applications using 5V logic and components. The compact design makes it suitable for embedded controllers, compact sensor interfaces, custom electronics, indicators and other applications where a small programmable controller is required.
