Built around the SIM808 module with an MT3337 GPS chipset, it provides voice calling, SMS, GPRS data, and GPS geolocation — all controlled over a single serial port via AT commands.\n\nThe GPS module offers significantly better performance than the FONA 3G's GPS, with −165 dBm tracking sensitivity, 22 tracking / 66 acquisition channels, and a 32-second cold start. The board includes LiPo battery charging, level shifting (2.8–5 V logic), a TRRS headphone jack, vibration motor driver, and uFL antenna connectors for both GSM and GPS antennas.\n\nKey Features\n\n\nSIM808 Quad-Band GSM + GPS – 850/900/1800/1900 MHz 2G + integrated MT3337 GPS\n\nVoice, SMS, and Data – Make/receive calls, send/receive SMS, GPRS data (TCP/IP, HTTP)\n\nLiPo Battery Charging – On-board charger via Micro-USB; requires 500 mAh+ battery\n\nLevel Shifting – Works with 2.8–5 V logic levels\n\nuFL Antenna Connectors – Separate uFL ports for GSM and GPS antennas\n\nTRRS Headphone Jack – Standard 4-pole jack for Android/iPhone-compatible headsets\n\nSpeaker + Mic Breakouts – Pads for external 32 Ω speaker and electret microphone\n\nVibration Motor Driver – PWM/buzzer output for silent notifications\n\nStandard SIM Slot – Accepts a 2G mini SIM card\n\nAT Command Interface – Auto baud detection; controllable via UART from any 3–5 V microcontroller\n\n\nGPS Specifications\n\n\nChannels: 22 tracking / 66 acquisition\n\nSignal: GPS L1 C/A code\n\nTracking Sensitivity: −165 dBm\n\nCold Start Sensitivity: −147 dBm\n\nTTFF Cold Start: ~32 s typical\n\nTTFF Warm Start: ~5 s typical\n\nTTFF Hot Start: ~1 s typical\n\nAccuracy: ~2.5 m\n\n\nAlso Available\n\n\nFONA 808 Shield – GSM + GPS for Arduino (shield form factor)\n\nFONA 800 Shield (without GPS)\n\nFONA Mini Cellular GSM Breakout – uFL Version (without GPS)\n\nFONA 3G – European Version (3G + GPS)\n\n\nRequired Accessories (Not Included)\n\n2G mini SIM card\nLiPo battery – 500 mAh or larger\nMicro-USB cable for charging\nExternal uFL GSM antenna\nExternal uFL passive GPS antenna\n\n\nIdeal For\n\nGPS asset tracking and geolocation with cellular reporting\nIoT projects requiring 2G data + GPS\nVoice and SMS-enabled embedded devices\nRemote monitoring and telemetry\n\n\nPackage Contents\n\n1× Adafruit FONA 808 Mini Cellular GSM + GPS Breakout\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9417,"title":"Default Title","sku":"AF-2542","price":97.45,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
