  • 4x Mesh evaluation boards - Inclusion of four board allows to evaluate a real mesh network with just one kit
  • 4x USB-A to micro-B cable
  • 1x Quick Start Guide

The EZ-BT Mesh Evaluation kit (CYBT-213043-MESH) enables the evaluation of SIG mesh functionality using the EZ-BT Bluetooth 5.0-qualified module CYBT-213043-02. The CYBT-213043-02, EZ-BT module is an integrated, fully-certified, 12.0 mm x 16.61 mm x 1.70 mm, programmable dual-mode Bluetooth module with Bluetooth mesh support designed to reduce time-to-market.

The CYBT-213043-02 module utilizes the Cypress CYW20819 silicon device. CYW20819 is an ultra-low-power (ULP) and highly integrated dual-mode Bluetooth 5.0 qualified device. The CYW20819’s low-power and integration capability addresses the requirements of both battery- and wall-powered applications that require BLE mesh, such as sensor nodes, locks, lighting, blind controllers, asset tracking, and many more Smart Home applications.

CYBT-213043-MESH kit is supported in ModusToolbox 2.2 with Bluetooth SDK 2.8 or later. The Bluetooth SDK includes a number of demo code examples that allow you to implement real-life mesh application such as a dimmable light (bulb), dimmer and a thermometer and likes just in few minutes. Cypress also provided a number of other code examples and snip codes for mesh functionality that are available on GitHub. These code examples can be searched and imported within ModusToolbox IDE.

Mesh board overview

Each mesh board included in the CYBT-213043-MESH kit features following:
