Adafruit Trinket Mini Microcontroller 5v Logic Compatible

It has an attiny85 processor, 8 kb of flash memory, and 5 programmable input/output pins. Thanks to the bootloader that comes pre-installed on it, it works just like an arduino when you connect it to your computer via usb. The card operates at a 5v logic level. It can be set to operate at a clock speed of 8 mhz or 16 mhz by the software. Although it is arduino compatible, some features are not available:

there is no serial port on the card.

some computers usb 3.0 ports do not recognize the bootloader on the card. To prevent this, you can connect it to a usb 2.0 port or you can connect a usb 2.0 capable hub (multiplexer) to the usb 3.0 port.

Specifications: attiny85 microcontroller, 8 kb flash (2. 75 kb used by bootloader), 512 bytes sram, 512 bytes eeprom

Ability to operate at 8 mhz or 16 mhz clock frequencies (selectable from software)

Possibility of programming with avrdude or arduino ide thanks to usb bootloader.

Mini usb socket (for power and programming)

Thanks to the regulator on it, it has a 16v power input (reverse voltage, overcurrent and thermal protected)

Green power led and red led connected to pin number 1

5 gpio pins (2 of which are used by usb. 1 analog input and 2 pwm output possibilities from the remaining 3.

hardware i2c/spi connection interfaces. Dimensions: 31mm x 15.5mm x 5mm

weight: 1.85 gr (excluding headers)
