Description
As the first wireless product in the Seeed XIAO family, Seeed XIAO BLE 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 capability 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. To better support IoT and TinyML AI projects, there is an advanced version "Seeed XIAO BLE Sense" that carries both 6-axis IMU and PDM microphones.
作為 Seeed XIAO 系列的第一款無線產品，Seeed XIAO BLE 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。 為了更好地支持 IoT 和 TinyML AI 項目，有一個高級版本“Seeed XIAO BLE Sense”，它同時搭載了 6 軸 IMU 和 PDM 麥克風。
Compare to XIAO RP2040, XIAO BLE has a richer 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 RP2040相比，XIAO BLE接口更加豐富。 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。
XIAO BLE is compatible to the XIAO expansion board.／XIAO BLE 兼容XIAO 擴展板。
