Balletto B1 DevKit

Get started with the Balletto B1 DevKit

The Balletto B1 DevKit (DK-B1) is a cost-effective, single-board platform that brings out all signals on the Balletto B1 MCU to easily access pins for power and performance profiling, prototyping, and more. The B1 MCU on the board has a Cortex-M55 CPU core with Helium-M Vector Extension, operating at 160 MHz, an Ethos-U55 neural network processor core with 128 MACs per cycle, 2MB of SRAM and 1.8MB of NVM, off-chip OSPI flash and PSRAM memory devices (64MB and 32MB respectively), a variety of digital and analog interfaces, plus and a BLE 5.3 + 802.15.4 radio subsystem with a chip antenna.

Alif Security Toolkit

Quick Start Guide (v3.2) shows how to install the Alif Security Toolkit (SETOOLS) for Ensemble and Balletto devices and shows some common commands used during application development.

STOP: Users of DK-B1 kits with A3 revision silicon should NOT update to version 1.109.00 or later! Please reference the Documentation Archive Library for previous versions.

NOTE: Beginning with the V1.107.00 release and onwards, the default tools configuration for the target device is the Ensemble E8 device used on the Ensemble E8 DevKit. If you are using any other kit or your own board, you will need to select the correct target device. See Section 4 of the latest Alif Security Toolkit Quick Start Guide for details on different ways to do this.

Alif Security Toolkit: (v1.111.01) for use with the Ensemble E1C and Balletto B1 devices or evaluation kits. After downloading your Toolkit, be sure to update your board to the same version by running the updateSystemPackage utility.
