{"title":"GNSS Flex Breakout Carrier Board","handle":"sparkfun-gnss-flex-breakout","url":"/products/sparkfun-gnss-flex-breakout","description":"This carrier board brings the GNSS Flex ecosystem out to a practical development breakout, so you can use your chosen GNSS Flex module on a breadboard, with a flight controller, or inside a custom navigation build. The standard 2x10 male headers accept a GNSS Flex module and expose its available interfaces.Connection options include native USB pass-through, a CH342 USB-to-UART bridge, Qwiic, µSD, Pixhawk-style JST ports, UART, I2C, SDIO, PPS/Event signals and antenna bridging via u.FL to SMA. Power can be supplied through USB or VIN, with jumper-configurable power behaviour for the JST ports.Onboard LEDs show module status including power, PPS, PVT and RTK. Depending on the GNSS Flex module selected, an external antenna may be required; modules with u.FL can connect directly, or you can jumper the module to the breakout's u.FL/SMA antenna bridge for a sturdier SMA antenna connection.Supporting documentation includes design files, schematic, KiCad files, board dimensions, STEP file, component datasheets, a hookup guide, Building a GNSS System, Qwiic information and the GitHub hardware repository.Features:Full Pin Access: Standard 0.1\"-pitch headers break out all module interfaces, including up to four UARTs, I²C, USB, SDIO, and dual PPS/Event signals.Dual-Mode USB: Connect directly to your module's native USB port or use the onboard CH342 USB-to-UART bridge for easy serial communication and configuration.Bridge disable: The bridge can be quickly disabled if you need exclusive access to the UART pins.Pixhawk-Ready JST Ports: Two 6-pin JST connectors with the standard Pixhawk pinout allow for a plug-and-play connection to flight controllers or telemetry radios for receiving RTCM correction data.Multiple Inputs: Provide power via any of the USB connectors or the dedicated VIN pin.Configurable Voltage Output: By default, the JST connectors output 5V to power peripherals.Jumper options: Onboard jumpers allow you to easily switch this to 3.3V or isolate the circuit completely, using the pin as a dedicated 5V input.Status indicators: Onboard LEDs provide instant visual feedback on the status of your GNSS module, including indicators for Power, PPS lock, PVT (Position, Velocity, Time) fix, and RTK fix.External antenna connection: GNSS Flex modules that require an external antenna will come with a U.FL connector.Antenna connection option: The antenna can be connected directly to the Flex module if desired.Sturdier antenna connection: Two SMA connectors are available on the SparkFun GNSS Flex Breakout.Antenna bridge: Each SMA connector is bridged to a U.FL connector.Specifications:GNSS Flex module header: 40-pin header for GNSS Flex modulesGNSS Flex module headers: Two 2x10-pin, 2mm-pitch male headersGNSS Flex header signal: PowerGNSS Flex header voltage: 3.3VGNSS Flex header power: Backup powerGNSS Flex header signal: USB bus detect (not a power source)GNSS Flex header signal: USB dataGNSS Flex header interface: UART (x4)GNSS Flex header interface: SD cardGNSS Flex header interface: I2C busGNSS Flex header signal: PPS signal (x2)GNSS Flex header indicators: LED indicators (x2)GNSS Flex header indicators: Event indicators (x2)USB connector: USB USB-C connectorUSB connector function: Provides a direct pass-through connection to the attached module's native USB interface (requires a USB-capable GNSS module)USB connector power: 5V power inputUART connector: UART USB-C connectorUART connector interface: Interfaces to UART1 and UART2 on the GNSS Flex Module via a CH342 interfaceUART connector power: 5V power inputJST connectors: JST connectors (x2)JST connector interface: Provides access to UART1 (TX & RX) plus I2C - for connection to a Pixhawk flight controllerJST connector interface: Provides access to UART2 with handshaking - for connection to a telemetry radioJST connector power: 5V power outputJST connector power option: Optional 3.3V power output - configured via jumpersJST connector power option: Optional 5V power input - when all other power sources are disconnectedAntenna bridges: Antenna bridges (x2)Antenna connector: u.FL connectorAntenna connector: SMA connectorStorage: µSD card socketQwiic: Qwiic connectorIndicator LEDs: Indicator LEDsPWR LED: PWR (Red)PPS LED: PPS (Yellow)RTK LED: RTK (White)PVT LED: PVT (Blue)Use it when you need flexible access to a GNSS Flex module for RTK navigation, Pixhawk integration, telemetry links, antenna testing or general GNSS development.","vendor":"SparkFun","product_type":"GNSS Breakout Board","in_stock":true,"options":[],"variants":[{"id":15783,"title":"Default Title","sku":"SF-GPS-28962","mpn":"GPS-28962","price":58.9,"on_sale":false,"in_stock":true,"available_quantity":91}]}
