TAIYO YUDEN's Tiny Bluetooth Low Energy Module with Built-in Antenna

You Taiyo Yuden has been a key module vendor for wireless devices and this time they developed a very small BLE module that can be used for various wireless applications.
The module model name is EYSHSNZWZ, and this module is developed based on Nordic nRF52 series.

Key features are listed below.

• Dimension: 3.25 x 8.55 x 0.85mm
• Bluetooth: Version 5.0
• Base chip: Nordic nRF52832 (ARM Cortex M4F) with S132 V5.0.0 SoftDevice
• Memory: 512kB Flash, 64kB RAM
• Interface: UART, SPI, I2C, GPIO
• Antenna: Built-in
• Crystal: 32kHz
• Certifications: Japan, USA, Canada, Bluetooth logo

​
This is extremely small BLE module!

As you can see in this application example, there are so many that you can consider using BLE.
Using this kind of small module will help product form factor to be small and save the areas for other features like sensors.
Also, it will save lots of effort that is required for engineers and product managers.

The evaluation board and kit are available from here.
You can order the board from Digikey.

There is an overview document of the BLE module lineup.
This will help you consider the best solution for your use case.
