Adafruit Feather 32u4 FONA

Overview

  • 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 FONA - our take on an 'all-in-one' Arduino-compatible + audio/sms/data capable cellular with built in USB and battery charging. Its an Adafruit Feather 32u4 with a FONA800 module.
  • 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.
  • Since you'll be taking this on the road, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. A 500mAh+ Lipoly battery is required for use, it keeps the cellular module happy during the high current spikes. Plug the Feather into microUSB to charge at 500mA.

      Specification

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

        • Measures 2.4" x 0.9" x 0.28" (61mm x 23mm x 7mm) without headers soldered in
        • Light as a (large?) feather - 8.2 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
        • 7 x PWM pins
        • 10 x analog inputs
        • Built in 500mA lipoly charger with charging status indicator LED
        • Pin #13 red LED for general purpose blinking
        • Power/enable pin for the 3.3V regulator
        • 4 mounting holes
        • Reset button

      Connect your Feather to the Internet or make phone calls with our trusted-and-tested FONA module. At the heart is a GSM cellular module (we use the latest SIM800) the size of a postage stamp. This module can do just about everything.

        • Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)
        • Make and receive voice calls using an external 8Ω speaker + electret microphone
        • Send and receive SMS messages
        • Send and receive GPRS data (TCP/IP, HTTP, etc.)
        • Scan and receive FM radio broadcasts (yeah, we don't exactly know why this was included but it works really well)
        • AT command interface with "auto baud" detection
        • Pair-able Bluetooth client interface with SPP (for controlling the module) as well as audio.

      You will also need some required accessories to make Feather FONA work. These are not included!

      • SIM Card! - A 2G Mini SIM card is required to do anything on the cellular network. US AT&T no longer sells 2G SIMs and will shut off their 2G network, so for American customers we recommend any T-Mobile or reseller (TING, SIMPLE mobile, etc) that uses the T-Mobile network.
      • Lipoly Battery - 500mAh or larger! This 500mAh battery, or this 1200mAh will work great.
      • MicroUSB cable for charging the battery.
      • External Antenna - We like this slim sticker-type, which plugs right in and has a nice long cable to keep the RF away from the feather. Alternatively, this straight SMA one or this right-angle SMA one will work but you'll also need a uFL to SMA adapter cable so you can connect to your SMA antenna
      • External Mic & Speaker - If you want to make phone calls, you'll also need this electric mic and mini 8 ohm speaker

        ABSOLUTELY A MUST for Omegaverse Girls!!!
        I ABSOLUTELY LOVE Jillian West and her books!!! I’m so happy I already bought book two and now I have to buy the others for the Assurance Security series!! Not gonna lie Val kind of annoyed me at the beginning but she grew on me!! Her men are chef’s kisses!!! Holt annoys me some but I can let it slide. I already bought part two so I’m going to be reading that in between work phone calls!!!! DON’T TELL MY BOSS 😂😂😂😂

        Baby bumps and bodyguards
        Format: Kindle
        Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

        Strong Omegaverse Comfort and a Attention Grabbing Plot
        Format: Kindle
        Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

        Interesting
        Format: Kindle
        So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

        I’m a little disappointed.
        Format: Kindle
        I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.
