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 withlow power consumption. It will be your best microcontroller for Bluetooth applications.
