BeagleConnect Freedom

2 Quick Start Guide 7

BeagleConnect Freedom BeagleConnect™ Freedom is an open-hardware wireless hardware platform developed by BeagleBoard.org and built around the TI CC1352P7 microcontroller, which supports both 2.4-GHz and long-range, low-power Sub-1 GHz wireless protocols. Rapidly prototyping of IoT applications is accelerated by hardware compatibility with over 1,000 mikroBUS add-on sensors, acutators, indicators and additional connectivity and storage options, and backed with software support utilizing the Zephyr scalable and modular real-time operating system, allowing developers to tailor the solution to their...

BeagleConnect Freedom

BeagleConnect™ Freedom is based on a TI Arm Cortex-M4 wireless-enabled microcontroller and is the first available BeagleConnect™ solution. It features: • BeagleConnect™ node device for Bluetooth Low-Energy (BLE) and Sub-GHz 802.15.4 long range wireless, • Works with BeaglePlay® gateway, • USB-based serial console and firmware updates, • On-board light and humidity/temperature sensors, • Buzzer, LEDs and buttons for user programming.

BeagleConnect Freedom 1.2 What makes BeagleConnect™ new and different? 1.2.1 Plug & Play approach BeagleConnect™ uses the collaboratively developed Linux kernel to contain the intelligence required to speak to these devices (sensors, actuators, and indicators), rather than relying on writing code on a microcontroller specific to these devices. Some existing solutions rely on large libraries of microcontroller code, but the integration of communications, maintenance of the library with a limited set of developer resources and other constraints to be explained later make those other solutions less...

BeagleConnect Freedom the software and provide mechanisms for updating firmware on BeagleConnect™ hardware. With a single, relatively small firmware load, the potential for bugs is kept low. With large user base, the potential for discovering and resolving bugs is high. BeagleConnect™ utilizes the mikroBUS standard. The mikroBUS standard interface is flexible enough for almost any typical sensor or indicator with hundreds of devices available. Note: Currently, we have support in the Linux kernel for a bit over 100 Click mikroBUS add-on boards from Mikroelektronika and are working with Mikroelektronika...

1. BeagleConnect Freedom board in enclosure Tip: For board files, 3D model, and more, you can checkout BeagleConnect Freedom repository on OpenBea-gle. To connect the SubGHz antenna with SMA connector to the BeagleConnect Freedom you just have to align, place and rotate the antenna clockwise as shown in the image below. To detach the antenna just twist it anti-clockwise. Boards come pre-flashed with Micropython. Read Using Micropython for more details. • Using BeagleConnect Greybus • Using Micropython • Using Zephyr

Demos & tutorials 5.1 Using Micropython Important: Currently under development Micropython is a great way to get started developing with BeagleConnect Freedom quickly. Flashed firmware BeagleConnect Freedom initial production firmware is release 0.0.3 of our own fork of Micropython. https://git.beagleboard.org/beagleconnect/zephyr/micropython/-/releases/0.0.3 You can verify this version by using mcumgr over a UDP connection or mcuboot over the serial console shell. Latest releases are part of our Zephyr SDK releases. https://git.beagleboard.org/beagleconnect/zephyr/zephyr/-/releases 0.0.3 The...

Download, unzip and flash the micropython-w-boot image. Repository: https://git.beagleboard.org/beagleconnect/zephyr/micropython Developing directly in Zephyr will not be ultimately required for end-users who won't touch the firmware running on BeagleConnect™ Freedom and will instead use the BeagleConnect™ Greybus functionality, but is important for early adopters as well as people looking to extend the functionality...
