LilyTiny - AVR ATtiny85 microcontroller module

A-Star 32U4 Micro

The platform is based on the Atmega 32U4 microcontroller with a default Arduino compatible bootloader, 26 O / I ports and a microUSB port. Polol 3145

This little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Adafruit 2124

FLORA is Adafruit\'s fully-featured wearable electronics platform. It\'s a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects. Adafruit 659

Dreamer Nano V4 - Arduino Leonardo compatible; ATmega 32U4

Small development kit with ATmega32u4 microcontroller. The board has 6 power, 6 analog and 17 digital pins, which makes it have similar capabilities to the Arduino UNO. Compatible with Arduino. Adafruit 3675

The A-Star 32U4 Mini ULV is a programmable module based on the ATmega32U4 from Atmel. Unlike competing products, it has an onboard switching step-up regulator that allows it to be powered efficiently from a 0.5 V to 5.5 V supply. Pololu 3102

Miniature development board with ATtiny817 microcontroller. It has analog inputs, PWM outputs and two STEMMA QT connectors. Adafruit 5233

Development board with ATmega32u4 microcontroller (AVR), 20 I / O lines, 7 PWM channels, 16 MHz quartz, micro-USB. Easy-to-use USB support libraries, sensors, displays, etc. are available. A000057

The Fio v3 is a new spin on the Arduino Fio hardware powered by the ATmega32U4. Not only is it small and LiPo-ready, it’s a very capable XBee-ready development board. DEV-11520

The A-Star 32U4 Mini LV is a programmable module based on the ATmega32U4 from Atmel. Unlike competing products, it has an onboard switching step-up/step-down regulator that allows it to be powered efficiently from a 2.7 V to 11.8 V supply. Pololu 3103

Adafruit 1222

The SparkFun Roshamglo is the new and fun way to play Rock-Paper-Scissors with your friends! The board uses the ATtiny84, and has an IR LED and receiver to communicate between badges. KIT-14130

Adafruit 1500

Module with ATmega32u4 microcontroller and 900 MHz wireless transceiver. The module can be used for transmission in the ISM 868 MHz band after the appropriate software configuration. The microcontroller is clocked at 8 MHz and works at 3.3 V. Adafruit 3076

At the Feather 32u4\'s heart is ATmega32u4 clocked at 8 MHz and at 3.3V logic. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. Adafruit 2795
