Overview
Description
The US159-DA14531EVZ Low Power Bluetooth® Pmod™ module enables the user to add low-power Bluetooth capability to any evaluation kit or microcontroller board equipped with a Pmod expansion capability. The board provides a standard Pmod Type 3A (Expanded UART) connection for the onboard Bluetooth 5.1 module.
The US159-DA14531EVZ features a Type 3A Pmod™ connector and incorporates the DA14531 SmartBond TINY™ Module, based on the world’s smallest and lowest power Bluetooth 5.1 System-on-Chip (SoC). Due to the standard connector and software support, the US159-DA14531EVZ is ideal for Renesas’ QuickConnect platform to rapidly create an Internet of Things (IoT) system.
