Update Seeed_XIAO_nRF52840_Sense.md

Browse source 
I guess the vendor documentation was corrected as this is the new version of that sensor on https://www.seeedstudio.com/Seeed-XIAO-BLE-Sense-nRF52840-p-5253.html

I was super confuse to read that this board could also `speak through the the microphone`. I guess that was lost in translation.

Seeed Studio XIAO nRF52840 (Sense) has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM® Cortex™-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz. With the capabilities of wireless connection, it still remains the Seeed Studio XIAO series classic form-factor of small and exquisite which can be used for wearable devices and Internet of Things projects. Furthermore, it only costs 5 μA in the deep sleep model and it supports battery charge management because of the BQ25101 chip.
In addition, the SENSE version of the board carries two extra onboard sensors. One of them is a digital microphone created through Pulse Density Modulation(PDM) module on the nRF52840 chip. It can receive audio data in real-time which allows it can be used for audio recognition. The board not only receives audio data but also can speak through the MSM261D3526H1CPM microphone. The other one is 6-axis Inertial Measurement Unit(IMU) which can be applied in TinyML projects like gesture recognition. These onboard sensors provide a great convenience for users and the ultra-small size feature of the board has still remained.

The same CircuitPython firmware can be used both for the Seed Studio XIAO nRF52840 with or without additional sensor.
