It's designed to connect sensors and peripherals to a BeagleBone or Linux host via sub-GHz wireless with up to 1 km range. The dual-band radio covers sub-1 GHz (287–1054 MHz) and 2.4 GHz bands, supporting BLE 5.0, IEEE 802.15.4, Wi-SUN, and Amazon Sidewalk protocols. Two mikroBUS sockets provide instant compatibility with over 1,000 MikroElektronika Click sensor boards — snap on a sensor board and start collecting data wirelessly. The board includes onboard TI OPT3001 light sensor and HDC2010 humidity/temperature sensor, a TI MSP430F5503 co-processor for USB-UART bridging, 2 MB external SPI flash, battery charger, and a plastic enclosure with attached sub-GHz antenna. It runs Zephyr RTOS and integrates with Linux via the Greybus protocol for seamless BeagleBone expansion. ## Where to Buy - [Electromaker](https://openhardware.directory/r?to=https%3A%2F%2Felectromaker.io%2Fshop%2Fproduct%2Fbeagleconnect-freedom&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) — $29.67 - [Mouser](https://openhardware.directory/r?to=https%3A%2F%2Fwww.mouser.com%2FProductDetail%2F102110577&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) — $29.67 - [DigiKey](https://openhardware.directory/r?to=https%3A%2F%2Fwww.digikey.com%2Fen%2Fproducts%2Fdetail%2F102110577&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) — $29.67 - [Farnell](https://openhardware.directory/r?to=https%3A%2F%2Fwww.farnell.com%2F&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) — $29.67 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.beagleboard.org%2Fboards%2Fbeagleconnect-freedom&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgit.beagleboard.org%2Fbeagleconnect%2Ffreedom&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.beagleboard.org%2Fboards%2Fbeagleconnect%2Ffreedom%2Findex.html&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.ti.com%2Flit%2Fds%2Fsymlink%2Fcc1352p7.pdf&ref=openhardware.directory&product=beagleconnect-freedom&source=md-export) ## Tags `beagleboard`, `cc1352`, `sub-ghz`, `iot`, `wireless`, `zephyr`, `mikrobus`, `sensor-network`, `open-hardware`, `ti` ## Images ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/ff9c521adb2e.png) ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/dde445480090.png) ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/1770a9b69639.png) ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/f41d77e61537.png) ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/351e7ac68e0e.webp) ![BeagleConnect Freedom](https://nbg1.your-objectstorage.com/openhardware-directory/entities/beagleconnect-freedom/2da6c0f649a8.png) > **Battery Powered:** Rechargeable (BQ2104 charger) --- [View full device page](https://openhardware.directory/devices/beagleconnect-freedom)
