Mini-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.
ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.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. 03ma - an astounding power draw reduction of 99.8 percent! What this means in practical terms is that if you’re powering one of these devices with a 105 milliamp hour (mAh) your theoretical battery drain time when not in use would go from around 10 hours to over 2600 hours (though the wake-up periods will likely shorten this number). Adafruit Industries, Unique & fun DIY electronics and kits Adafruit Trinket - Mini Microcontroller - 5V Logic : ID 1501 - Deprecation Warning: The Trinket bit-bang USB technique it uses doesnt work as well as it did in 2014, many modern computers wont work well. His procedure goes through a couple power-saving steps that can be applied individually, including a software solution that puts the processor to sleep, disabling the power LED, and finally disabling a resistor that was using power. So while we still carry the Trinket so that people can maintain some older projects, we no longer recommend it. On the other hand, there are a few drawbacks to his methods, including the obvious lack of a power LED, and the fact that the resistor helped with USB programming, meaning you’ll need to program via the FTDI header. This project interfaces Trinket to the the Adafruit DS1307 real-time clock (RTC) breakout board to form a clock. Toward the end of the video, he also points out an alternative called the Moteino, which runs at a much lower power consumption (5. But rather than use the traditional digital display, the display is done using two analog meters. Trinket Adafruit Mini Microcontroller - 3.3V Logic - MicroUSB. The Trinket can output to a meter without digital to analog converters. Trinket may be small, but do not be fooled by its size Its a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power.
