Attiny85는 작은 크기에도 불구하고 8K 플래쉬, 5개의 I/O핀(아날로그 입력, PWM출력 포함)을 가지고 있습니다.
USB 부트로더가 탑재되어 있어 USB 케이블을 통해 아두이노처럼 프로그래밍이 가능합니다.
Trinket 3V는 3V 로직과 사용되며, 리포 배터리를 이용하여 전원을 공급할 수 있습니다. 8Mhz에서만 동작합니다.
아두이노 IDE를 통하여 프로그래밍 할 수 있습니다만 100% 호환되지는 않습니다. 아래 내용 참조.
Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data
Some computers' USB v3 ports don't recognize the Trinket's bootloader. Simply use a USB v2 port or a USB hub in between
특징
ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM
Internal oscillator runs at 8MHz, but can be doubled in software for 16MHz(5V only)
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)
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.
We really worked hard on the bootloader process to make it rugged and foolproof, this board wont up and die on you in the middle of a project!
~5.25K bytes available for use (2.75K taken for the bootloader)
Available in both 3V and 5V flavors
On-board 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout. Up to 16V input, reverse-polarity protection, thermal and current-limit protection.
Power with either USB or external output (such as a battery) - it'll automatically switch over
On-board green power LED and red pin #1 LED
Reset button for entering the bootloader or restarting the program. No need to unplug/replug the board every time you want to reset or update!
5 GPIO - 2 shared with the USB interface. The 3 independent IO pins have 1 analog input and 2 PWM output as well. The 2 shared IO pins have 2 more analog inputs and one more PWM output.
Hardware I2C / SPI capability for breakout & sensor interfacing.
