Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

AF-2010

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. It's like an Arduino Pro Mini with more pins and USB tossed in.

SF-COM-13448

This is Atmel’s high performance, low power 8-bit AVR ATMega328 microcontroller in a pint-sized TQFP package. Yes, you really can solder that.

AF-3677

What's smaller than a Feather but larger than a Trinket? It's an Itsy Bitsy! Small, powerful, Arduino-compatible - this microcontroller board is perfect when you want something very compact, but still with a bunch of pins.

SF-PGM-09825

This new version uses an SMD 5x2 header. This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDude, and is tested extensively on a Windows desktop. Based on Dick Streefland’s USBtiny and Limor Fried’s USBtinyISP. This is a low-cost progr...

SF-PGM-11801

The ATtiny45 and 85 are a couple of really cool little MCUs but did you know you can program them in Arduino? That’s right, now you can shrink your Arduino projects down to “tiny size” by moving your code straight over to these small but capable ICs. The standard method for pr...

AF-2590

We sure love the ATmega328 here at Adafruit, and we use them a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Pro Trinket 3V ...

AF-3406

The Adafruit Feather nRF52 Bluefruit is our latest easy-to-use all-in-one Bluetooth Low Energy board, with a native-bluetooth chip, the nRF52832!  It's our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB and battery charging. We have other b...

SF-DEV-09215

This is a handy AVR programming cable that incorporates both the 10-pin and 6-pin ISP programming interfaces.

SF-COM-11232

The ATtiny84 is another of Atmel’s little tiny 8-Bit Processors. 8K of program space, 12 I/O lines, and 8-channel 10 bit ADC. It will run up to 20MHz with an external crystal and can be programmed in circuit.

SF-DEV-11643

When you think about a piece of equipment like a mixed signal oscilloscope you usually think of, well, a piece of equipment. What you probably don’t imagine is a DIP package. The XMEGA Xprotolab is exactly that: The first ever mixed signal oscilloscope, logic analyzer and arbi...
