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.

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 Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.

Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends.

The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs the same capability as an Arduino UNO. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller.

The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box!

Here's some things you may have to consider when adapting Arduino sketches:

• Pins #2 and #7 are not available (they are exclusively for USB)
• The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz.
• The onboard power supply is a 3.3V regulator and it can provide 150mA output
• You cannot plug shields directly into the Pro Trinket
• There is no Serial-to-USB chip onboard. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. The USB connection is for uploading new code only.
• The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes. The bootloader does not affect RAM usage.

Here's some handy specifications:

• ATmega328P onboard chip in QFN package running at 3.3V logic
• 12MHz clock rate, 28K FLASH available
• USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).
• Also has headers for an FTDI port for reprogramming
• Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.
• On-board 3.3V power regulator with 150mA output capability and ultra-low dropout. Up to 16V input, reverse-polarity protection, thermal and current-limit protection.
• Power with either USB or external output (such as a battery) - it'll automatically switch over
• On-board green power LED and red pin #13 LED
• Reset button for entering the bootloader or restarting the program.
• Works with 99% of existing Arduino sketches (anything that doesn't use more than 28K, and doesn't require pins #2 and #7)
• Mounting holes! Yeah!

Once headers are installed they can be fitted into 0.6" wide sockets

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.

This is the Adafruit Feather 32u4 LoRa Radio (RFM9x) - our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 868/915 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi.

This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically.

At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Flora. 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.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

Here's some handy specs! Like all Feather 32u4's you get:

• Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
• Light as a (large?) feather - 5.5 grams
• ATmega32u4 @ 8MHz with 3.3V logic/power
• 3.3V regulator with 500mA peak current output
• USB native support, comes with USB bootloader and serial port debugging
• You also get tons of pins - 20 GPIO pins
• Hardware Serial, hardware I2C, hardware SPI support
• 8 x PWM pins
• 10 x analog inputs
• Built in 100mA lipoly charger with charging status indicator LED
• Pin #13 red LED for general purpose blinking
• Power/enable pin
• 4 mounting holes
• Reset button

This Feather 32u4 LoRa Radio uses the extra space left over to add an RFM9x LoRa 868/915 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).

• SX1276 LoRa® based module with SPI interface
• Packet radio with ready-to-go Arduino libraries
• Uses the license-free ISM bands (ITU "Europe" @ 433MHz and ITU "Americas" @ 900MHz)
• +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.
• Simple wire antenna or spot for uFL connector

Our initial tests with default library settings: over 1.2mi/2Km line-of-sight with wire quarter-wave antennas. (With setting tweaking and directional antennas, 20Km is possible).

Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some headers so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Lipoly battery and USB cable not included but we do have lots of options in the shop if you'd like!

Say "Hi!" to the WICED Feather! Perfect for your next Internet connected project, with a powerful processor and WiFi core that can take anything you throw at it.

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. This is the Adafruit WICED Feather - it's our most powerful Feather yet!

The WICED Feather is based on Cypress (formerly Broadcom) WICED (Wireless Internet Connectivity for Embedded Devices) platform, and is paired up with a powerful STM32F205 ARM Cortex M3 processor running at 120MHz, with support for TLS 1.2 to access sites and web services safely and securely.

We spent a lot of time adding support for this processor and WiFi chipset to the Arduino IDE you know and love. Programming doesn't rely on any online or closed toolsets to build, flash or run your code. You write your code in the Arduino IDE using the same standard libraries you've always used (Wire, SPI, etc.), compile locally, and the device is flashed directly from the IDE over USB.

Since the WICED Feather is based on the standard Adafruit Feather layout, you also have instant access to a variety of Feather Wings, as well as all the usual standard breakouts available from Adafruit or other vendors.

After more than a year of full time effort in the making, we think it's the best and most flexible WiFi development board out there, and the easiest way to get your TCP/IP-based project off the ground without sacrificing flexibility or security. We even cooked in some built-in libraries in the WiFi core, such as TCP client and Server, HTTP client and server, and MQTT client (with easy Adafruit IO interfacing). It can even work with Amazon AWS IoT!

Please note: this is a really cool product but it's also very advanced and there may be firmware updates, tweaks and fixes as we have more people use it. For that reason we are calling this the Developer Edition! This chipset is not identical to the Arduino standard-supported Atmega series and many libraries that are written specifically for AVR will not compile or work with the STM32!

The WICED Feather has the following key features:

• Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
• Light as a (large?) feather - 5.7 grams
• STM32F205RG 120MHz ARM Cortex M3 MCU
• BCM43362 802.11b/G/N radio
• 128KB SRAM and 1024KB flash memory (total)
• 16KB SRAM and 128KB flash available for user code
• 16MBit (2MB) SPI flash for additional data storage
• Built in Real Time Clock (RTC) with optional external battery supply
• Hardware SPI and I2C (including clock-stretching)
• 12 standard GPIO pins, with additional GPIOs available via SPI, UART and I2C pins
• 7 standard PWM outputs, with additional outputs available via SPI, UART and I2C pins
• Up to eight 12-bit ADC inputs
• Two 12-bit DAC outputs (Pin A4)
• Up to 3 UARTs (including one with full HW flow control)
• TLS 1.2 support to access secure HTTPS and TCP servers
• On board single-cell LIPO charging and battery monitoring
• Fast and easy firmware updates to keep your module up to date
• Based on the excellent community-supported Maple project
