Adafruit trinket 5v easy projects2/14/2023 The bootloader does not affect RAM usage.Īdafruit Pro Trinket - 5V 16MHz - General Specifications The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.The USB connection is for uploading new code only. 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 5V regulator can provide 150mA output, not 800mA out.Pins #2 and #7 are not available (they are exclusively for USB).Here are some things you may have to consider when adapting Arduino sketches: Adafruit Pro Trinket - 5V 16MHz 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 16MHz clock which means it's good when you want a lower-power and lower-voltage setup. It also has Optiboot support, so you can either program your Adafruit Pro Trinket - 5V 16MHz over USB or with a FTDI cable just like the Pro Mini and friends.Īdafruit Pro Trinket - 5V 16MHz uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. Like the Trinket, Adafruit Pro Trinket - 5V 16MHz has onboard USB bootloading support and a MicroUSB jack. It has 18 GPIO, 2 extra analog inputs, 28K flash and 2K of RAM. Adafruit Pro Trinket - 5V 16MHz designed for projects in which users need more pins, more flash and more RAM. It's like an Arduino Pro Mini with more pins and USB tossed in. Adafruit Pro Trinket - 5V 16MHz combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328.
