Overview
The BeagleConnect Freedom is an open-source wireless IoT development board from BeagleBoard.org built around the Texas Instruments CC1352P7 multi-band wireless MCU. 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.
