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.
