Description
As the advanced version of the board XIAO BLE, Seeed XIAO BLE 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 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.
作為 XIAO BLE 板的高級版本，Seeed XIAO BLE Sense 配備了功能強大的 Nordic nRF52840 MCU，該 MCU 採用藍牙 5.0 模塊設計，圍繞 32 位 ARM® Cortex™-M4 CPU 和浮點單元 (FPU) 構建工作頻率為 64MHz。具備無線連接能力，依然是Seeed XIAO系列經典的小巧精緻外形，可用於可穿戴設備和物聯網項目。此外，它在深度睡眠模式下僅需 5 μA，並且由於採用 BQ25101 芯片，它支持電池充電管理。
In addition, it 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.
此外，它還帶有兩個額外的板載傳感器。其中之一是通過 nRF52840 芯片上的脈衝密度調製 (PDM) 模塊創建的數字麥克風。它可以實時接收音頻數據，可用於音頻識別。該板不僅可以接收音頻數據，還可以通過 MSM261D3526H1CPM 麥克風講話。另一種是 6 軸慣性測量單元（IMU），可應用於手勢識別等 TinyML 項目。這些板載傳感器為用戶提供了極大的便利，並且板子的超小尺寸特性仍然保留。
Same as XIAO BLE, Seeed XIAO BLE Sense contains a wealthy interface. The first thing to note is that the Near Field Communication(NFC) is functional on the board. Secondly, there is a tiny and elegant reset button on one side of the Type-C interface. On the other side, it is designed in a three-in-one LED along with a power LED. There are 11 digital i/o that can be used as PWM pins and 6 analog i/o that can be used as ADC pins. It supports UART, IIC, and SPI all three common serial ports. Same as Seeed XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages.
與XIAO BLE一樣，Seeed XIAO BLE Sense包含豐富的接口。首先要注意的是板上的近場通信 (NFC) 功能。其次，Type-C接口的一側有一個小巧精緻的重置按鈕。另一方面，它被設計成一個三合一的LED和一個電源LED。有 11 個可用作 PWM 引腳的數字 I/O 和 6 個可用作 ADC 引腳的模擬 I/O。它支持 UART、IIC 和 SPI 所有三種常見的串口。與 Seeed XIAO RP2040 相同，它具有板載 2 MB 閃存，這意味著它也可以通過 Arduino、MicroPython、CircuitPython 或其他程序語言進行編程。
