Beetle 3 Medium Circuit Board.

Getting Started

The Arm Beetle IoT evaluation board is built around the Arm CoreLink SSE-100 Subsystem, which allows design teams to create IoT endpoints faster and with lower risk. Arm’s scalable IP solutions are designed to target across the value chain, from sensors to servers. Arm’s IoT subsystem with Mbed OS is a complete reference system, that reduces the complexity and risk of a SoC design for IoT endpoints. The subsystem features a range of peripherals and interfaces. It is specifically designed for use with Cortex-M processors and Arm Cordio Bluetooth Smart Radio IP. Arm has taken this subsystem and generated a proof of concept test chip called Beetle.

Key benefits of the Arm Beetle board include:

  • Single-chip Cortex-M3 based IoT design
  • Features embedded Flash and Bluetooth
  • Evaluate and develop IoT applications 

Applications

Evaluation of Arm IP for IoT in a system context.

Key product highlights

The central element of the platform is the IoT subsystem, which is pre-validated allowing the user to hit the ground running. Arm extended the IoT subsystem, attaching the Arm Cortex-M3 processor, the Arm Cordio Bluetooth Smart radio, the TSMC embedded flash and a host of other complementary peripherals to create the Beetle test-chip.

The design is fully compliant with Arm’s Mbed OS IoT software framework, which enables rapid development and prototyping. It is loaded with debug features including: JTAG, SWD, CMSIS-DAP and TRACE. The Beetle board has support for expansion using Arduino® headers. It is an ideal platform for the evaluation of an Arm CoreLink SSE-100 Subsystem IoT subsystem.

A microcontroller-based configuration mechanism provides an easy, USB-based, plug-and-play method for programming software and firmware into the system flash memory from an attached PC.
