Also has headers for an FTDI port for reprogramming. USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications). ATmega328P onboard chip in QFN package running at 3.3V logic. The bootloader does not affect RAM usage. #ADAFRUIT TRINKET 3V PRO#
The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.
#ADAFRUIT TRINKET 3V CODE#
The USB connection is for uploading new code only.
#ADAFRUIT TRINKET 3V SERIAL#
This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection.
There is no Serial-to-USB chip onboard. You cannot plug shields directly into the Pro Trinket. The onboard power supply is a 3.3V regulator and it can provide 150mA output. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Pins #2 and #7 are not available (they are exclusively for USB). Here's some things you may have to consider when adapting Arduino sketches: Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs the same capability as an Arduino UNO. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. It's like an Arduino Pro Mini with more pins and USB tossed in. Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. All have built-in USB and are comparable in price! The ItsyBitsy's especially are about the same size and have native USB and tons of pins, so they're a very close compatible. So while we still carry the Pro Trinket so that people can maintain some older projects, we no longer recommend it. Please check out the Metro Mini (ATmega328 5V 16 MHz), ItsyBitsy 32u4 5V 16MHz, ItsyBitsy 32u4 3.3V 8MHz or ItsyBitsy M0 3V 48MHz. Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.Deprecation Warning: The Pro Trinket bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. #ADAFRUIT TRINKET 3V 32 BIT#
48 MHz 32 bit processor - 6x as fast as ATtiny85 (not even taking into account 32-bit speedups). 32 KB RAM - 64x as much as 512 bytes on ATtiny85. 256KB Flash - 32x as much as 8 KB on ATtiny85. Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit Cortex M0+. Same size, form-factor, and pinout as classic Trinket. Here are some of the updates you can look forward to when using Trinket M0: When you're done, unplug the Trinket M0 and your code will go with you. #ADAFRUIT TRINKET 3V INSTALL#
No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. When you plug it in, it will show up as a very small disk drive with main.py on it. The most exciting part of the Trinket M0 is that while you can use it with the Arduino IDE, we are shipping it with CircuitPython on board. It's just as small, and it's easier to use, so you can do more. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. The Adafruit Trinket M0 is a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power.
