Adafruit Industries, Unique & fun DIY electronics and kits Adafruit Trinket - Mini Microcontroller - 5V Logic ID: 1501 - As of October 9th, 2015 the 5V Trinket comes. In this tutorial you will learn how to use the Adafruit Pro Trinket board and. This is the hardware serial. Double click on Trinket, 'Update Driver Software. I'm trying to use Software Serial on the Pro Trinket 3V and getting. There is no Serial-to-USB chip. //learn.adafruit.com/introducing-pro-trinket Page 8.

The Trinket has a USB port that is used for bootloading. But the Trinket can only become a low-speed USB device because of its limited hardware.

Adafruit Trinket Pro

USB standards prevents low speed USB devices to truly act as virtual serial ports, which is why we cannot use a serial terminal to communicate with the Trinket directly. However, there’s a work-around for this problem. In Windows, you can emulate a fake serial port bridge using a utility named com0com. In this tutorial, you’ll see how we can write a middle-man program that communicates with the Trinket and com0com, so that a serial terminal (such as the one built into Arduino IDE) can talk with the other end of com0com. And versions. Trinket may be small, but do not be fooled by its size!

It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation.

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. It’s our lowest-cost arduino-IDE programmable board! The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM ‘analog’ outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board.

You can’t stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. There are two versions of the Trinket. One is and one is. Both work the same, but have different operating logic voltages.

Use the 3V one to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery. The 3V version should only run at 8 MHz.

Use the 5V one for sensors and components that can use or require 5V logic. The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency. Here are some useful specifications!. 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. 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). 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. 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.

Adafruit Trinket Set Up

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.

Mounting holes!. Really really small. Dimensions: 1.2″ x 0.6″ x 0.2″ / 31mm x 15.5 x 5mm, 1.85 grams (no headers).

Distributors and hackerspaces can get them now too! – here and you can get.

You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. There are some things you trade off for such a small and low cost microcontroller!. 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 There are two versions of the Trinket.

One is 3V and one is 5V. Both work the same, but have different operating logic voltages.
