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. 5 GPIO - 2 shared with the USB interface. The Adafruit Trinket M0 is a tiny (27 mm x 15 mm) ARM development board with an onboard RGB LED, USB port, and range of I/O broken out onto 5 pins.No need to unplug/replug the board every time you want to reset or update! 03ma an astounding power draw reduction of 99.
#ADAFRUIT TRINKET CURRENT HOW TO#
Reset button for entering the bootloader or restarting the program. To this end, as seen the video below, hacker Jeremy Gilbert shows us how to optimize an Adafruit Pro Trinket to go from using 15 milliamps (mA) when not really doing anything to around.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.Up to 16V input, reverse-polarity protection, thermal and current-limit protection.Onboard 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout.~5.25K bytes available for use (2.75K taken for the bootloader).Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude (with a simple config modification) and/or the Arduino IDE (with a few simple config modifications).Internal oscillator runs at 8MHz but can be doubled in software for 16MHz.Converted voltage reading is about 2V out of 3.3 V device can handle. 5 V to one of the I/O ports, and was getting a voltage reading of about 40,000 out of the 65535 scale that the device outputs voltages in. ATtiny85 on-board, 8K of flash, 512 bytes of SRAM, 512 bytes of EEPROM Ive been working on trying to get a voltage reading from an input to the Trinket m0.
