The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency.Įven though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. Use the 5V one for sensors and components that can use or require 5V logic. The noise while the MAX4466 is powered from the Feather could be related to power spikes caused by the Wifi radio, but it looks like you might be getting some EMF noise too. 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 noise in the output is roughly in sync with the 0.046s burst rate you mentioned. Both work the same but have different operating logic voltages. You can't stack a big shield on it but for many small & simple projects, the Trinket will be your go-to platform. In fact, we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. 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. It's our lowest-cost Arduino-IDE programmable board! Filed under: Adafruit Video, ask-an-engineer, components & parts, digikey, EYE on NPI, power supply. On-board green power LED and red pin 1 LED.

#ADAFRUIT TRINKET POWER SUPPLY PRO#
9V (supply) -> adafruit pro trinket 5v -> 5v servo (Hitec 31055S HS-55) and 3.3 RFID reader (desc below) This is my first project with the arduino and I want to make sure i get it right. Up to 16V input, reverse-polarity protection, thermal and current-limit protection. Also I will be powering the trinket with a 9v powerpack (6 AA batteries) What would I need to correctly power this project How I planned on doing it was. 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. On-board 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. 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.
