Seeed Studio XIAO BLE nRF52840

The tiny Seeed Studio XIAO Series development boards are literally the size of a thumb, yet they share a similar hardware design. Here, the half of the feature that is represented by the code name “XIAO” is “Tiny,” while the other half will be “Puissant.”

For the first time, the Seeed Studio XIAO nRF52840 is wirelessly capable and supports Bluetooth 5.0. It can also run at a low power consumption. For Bluetooth applications, this microcontroller will be your best choice.

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.
