The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, 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...

Trinket's got a big sister in town - the Pro Trinket 5V ! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in, so delicious. 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. That's why we designed Pro...

As of October 9th, 2015 the 5V Trinket comes with a micro-USB connector instead of a mini-USB connector! Trinket may be small, but do not be fooled by its size!

Regulate the power to a variety of electronics with this four Relay Shield for Photon ! The Relay Shield allows you to control any normal outlet or high voltage product from anywhere. The shield comes with four relays that are rated at a max of 220V @10Amp allowing you to control any electric appliance rated at under 2000 Watts. Note that you *will* need a DC adapter to power the relays! We recommend this one.

The Particle Shield Shield converts the footprint and pins of your Photon into that of an Arduino, allowing for use of existing Arduino shields and accessories. This shield converts the pin mapping of the Photon to the Arduino pin layout and provides a voltage translation of 3.3V to/from 5V. Note that Arduino libraries are not necessarily going to work without some porting, but for many basic shields that do not depend on the specific Arduino...
