The 3V version should only run at 8 MHz.Įven though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. This is the code for the Pro Trinket bootloader. Use 3V Trinket to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery. The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. Use this 5V Trinket for sensors and components that can use or require 5V logic. Both work the same, but have different operating logic voltages. The Adafruit Trinket comes in 2 variations, 5V and 3V logic. It's Adafruit's lowest-cost arduino-IDE programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design.

Just connect it to a computer via USB and use it as a mini Arduino board. This tiny little board runs powerful ATTiny85 micro controller and has 8K of flash and 5 IO Pins. The bootloader does not affect RAM usage. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes. The USB connection is for uploading new code only. Works with many basic Arduino libraries including Adafruit Neopixel!ĭimensions: 1.2" x 0.6" x 0.2" / 31mm x 15.Are you looking for a microcontroller for your project and just need a few IO pins? Adafruit's Trinket Mini Microcontroller is the board for you. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection.Hardware I2C / SPI capability for breakout & sensor interfacing.The 2 shared IO pins have 2 more analog inputs and one more PWM output. The 3 independent IO pins have 1 analog input and 2 PWM output as well. Reset button for entering the bootloader or restarting the program. Simply use a USB v2 port or a USB hub in between. Some computers USB v3 ports dont recognize the Trinkets bootloader. 5 GPIO - 2 shared with the USB interface. Adafruit Industries 1501 Embedded System Development Boards and Kits.Reset button for entering the bootloader or restarting the program.On-board green power LED and red pin #1 LED.Power with either USB or external output (such as a battery) - it'll automatically switch over.On-board 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout.Available memory: ~5.25K bytes for use (2.75K taken for the bootloader).Bootloader is rugged and foolproof, this board wont up and die on you in the middle of a project!.Micro-USB jack for power and/or USB data uploading.Oscillator frequency: 8MHz 3V, 8Mhz 5V, 16Mhz 5V.Memory: 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.Simply use a USB v2 port or a USB hub in between This means its possible to accidentally overwrite the bootloader (or even if you unplug the Trinket while uploading it might have difficulties from then on) You can use an Arduino UNO to re-program the bootloader onto your Trinket (or Gemma). Atmel AVR 8-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data The ATtiny85 does not have a protected-bootloader section.Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. Both work the same, but have different operating logic voltages.The 3V version should only run at 8 MHz, whereas the 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. There are two versions of the Trinket boards available, One is 3V and one is 5V. Its comes with USB bootloader, so you can plug it into any computer and reprogram it over a USB port just like an Arduino. Its a low cost, small size board, perfect for when you don't want to use your expensive development board,it's lowest-cost arduino-IDE programmable board.Its comes with 8K flash memory and has 5 GPIO pins, including analog inputs and PWM outputs. Trinket is a tiny microcontroller board, built around Atmel ATtiny85 IC, a little chip with a lot of power.
