Note: Due to small size heating issue will be generated, but will not affect the working of the product.
To avoid excessive heating you can use external heatsink.

Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name “XIAO” here represents its half feature “Tiny”, and the other half will be “Puissant”.

Seeed Studio XIAO nRF52840 is carrying wireless capability for the first time and it supports Bluetooth 5.0, also able to operate with low power consumption. It will be your best microcontroller for Bluetooth applications.
