BeagleConnect Freedom
Overview
BeagleBoard.org BeagleConnect Freedom is a wireless Internet of Things board based on the SimpleLink multi-Standard CC1352P7 wireless MCU.
Hardware
BeagleBoard.org BeagleConnect Freedom board features the TI CC1352P7 wireless microcontroller. The BeagleConnect Freedom is the first available BeagleConnect solution consisting of a board and a case which ships programmed and ready to be used.
BeagleConnect Freedom board runs the Zephyr RTOS and has mikroBUS ports along with BLE and Sub-GHz radios on it.
The CC1352P7 wireless MCU has a 48 MHz Arm Cortex-M4F SoC and a Bluetooth Low Energy and IEEE 802.15.4.
The board also features a TI MSP430F5503 microcontroller used as a USB-to-serial bridge and GPIO expander.
