Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the Adafruit CP2102N Friend! The CP2102N is very similar to the CP2104. Despite having a name with a lower number, its actually considered the...

Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your everyday serial data from a microcontroller to computer. What now? Enter the Adafruit CH9102F Friend, a version of our popular USB-Serial 'friend' breakouts that uses the affordable (and available) CH9102F - a 'near...

Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the FTDI Friend! The FTDI Friend is a tweaked out FTDI FT232RL chip adapter. Sure, like the well-known FTDI cable, it can provide power to your project...

The new and improved Programmer Shield is essentially a USB-JTAG converter that gives advanced users complete access to the Photon's memory space. It supports openOCD and the WICED SDK, and is built around the FT2232H high speed USB FIFO. Unlike the previous Programmer Shield, it is fully standalone and requires no third-party programmers. In addition to providing a...

The Seeeduino XIAO Expansion Board is a great add-on board with a little-bit-of-everything. It works wonderfully with our QT Py boards so we're stocking it for folks to plug in their SAMD21 QT Py or RP2040 QT Py. It enables prototyping in an easy and quick way and with so many hardware add-ons, you can quickly explore near-infinite possibilities of Arduino and...

Introducing the MENTA, a portable minty Arduino-compatible project that fits into a common mint tin. We took our super popular Boarduino series, and wrapped it with a prototyping area into a rounded PCB that slots directly into an Altoids-sized metal tin. We included everything you expect to jump-start your project: DC power adapter jack with polarity protection....

Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE Micro - it's an Atmega32u4 chip (same as used as in the Adafruit Flora or Arduino...

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...

Discontinued - you can grab Adafruit CP2102N Friend - USB to Serial Converter instead! Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the Adafruit CP2104 Friend! This is a high-quality CP2104...

The Cloud from Seeeduino is a microcontroller based around the Dragino WiFi IoT module HE and the classic ATmega32u4. This board is Arduino compatible with built-in ethernet and WiFi support. There's also a USB-A port that makes it good for designing prototypes that need network connection. You can use this as a compatible board the now-discontinued Arduino Yun. The...

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...

The Particle Power Shield is the best way to—you guessed it—provide power to your mobile Particle projects. Based around the MCP73871 battery management controller, this shield allows you to simultaneously power a Photon and charge a connected Li-Ion or Li-Po battery. You'll also be able to monitor battery levels using the Photon itself, which makes the...
