SIM808 GSM GPRS Module is at the heart of our Adafruit FONA 808 – Mini Cellular GSM + GPS Breakout. For people who want to integrate a cellular (GSM/GPRS) module into their design without the full breakout, this hand-solderable module is pretty nice! Please note we don’t provide any tech support for this module, but we do have a schematic as well as a collection of datasheets and app notes that can be used to interface.
Quad-band 850/900/1800/1900MHz – connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)
Fully-integrated GPS (MT3336 chipset with -165 dBm tracking sensitivity) that can be controlled and query over the same serial port
Make and receive voice calls using a headset or an external 32Ω speaker + electret microphone
Send and receive SMS messages
Send and receive GPRS data (TCP/IP, HTTP, etc.)
PWM/Buzzer vibrational motor control
AT command interface with "auto baud" detection
Here's the GPS specifications:
22 tracking /66 acquisition channels
GPS L1 C/A code
Tracking: -165 dBm
Cold starts : -147 dBm
Cold starts: 30s (typ.)
Hot starts: 1s (typ.)
Warm starts: 28s (typ.)
Accuracy: approx 2.5 meters
You’ll need to add all of the supporting circuitry that is required, such as antennas, power regulation, any level shifting, LEDs, etc!

As 2022 starts,
let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here. firstname.lastname@example.org VIDEO
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the
drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
