Designed for wearable and IoT applications, it supports multiple programming languages and offers a rich interface with UART, IIC, SPI, and 2MB flash memory, all within a sleek 21x17.5mm form factor. ## Description As an advanced version of the XIAO BLE board, 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 64 MHz. With the wireless connection capabilities, it remains the classic Seeed XIAO series form factor of small and exquisite that can be used for portable devices and Internet of Things projects. In addition, it only costs 5ΞΌA in the deep sleep model and supports battery charge management thanks to the BQ25101 chip. It also has two additional sensors on board. One of them is a digital microphone created through the pulse density modulation module (PDM) on the nRF52840 chip. It can receive real-time audio data, allowing it to be used for audio recognition. The board not only receives audio data, but can also talk through the MSM261D3526H1CPM microphone. The other is the 6-axis inertial measurement unit (IMU) that can be applied in TinyML projects such as gesture recognition. These built-in sensors provide great convenience for users and the ultra-small size feature of the board has still been maintained. Like XIAO BLE, Seeed XIAO BLE Sense contains a rich interface. The first thing to keep in mind is that Near Field Communication (NFC) is functional on the board. Secondly, there is a small and elegant reset button on one side of the Type-C interface.On the other hand, 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. Supports UART, IIC and SPI all three common serial ports. Like Seeed XIAO RP2040, it has a built-in flash of 2 MB, which means it can also be programmed by Arduino, MicroPython, CircuitPython or other program languages. ## Features - Powerful CPU - As the advanced version of the XIAO BLE board, Seeed XIAO BLE Sense features a powerful Nordic nRF52840 MCU developed in a Bluetooth 5.0 module that runs around a 32-bit ARM Cortex-M4 CPU with floating-point unit (FPU) at 64MHz. - WIRELESS FUNCTIONS - XIAO BLE Sense features Bluetooth 5.0 NFC module with built-in antenna. With the wireless connection capabilities, it remains the classic form factor of the Seeed XIAO series, small and elegant, which can be used for portable devices and Internet of Things projects. - 【Rich interface】 First, the Near Field Communication (NFC) on the board is functional. Secondly, there is a small and stylish reset button on one side of the Type-C interface.It is designed in a 3-in-1 LED along with a power LED. It supports UART, IIC and SPI, all three common serial ports. Like Seeed XIAO RP2040, it features a built-in 2MB flash, meaning it can also be programmed from Arduino, MicroPython, CircuitPython or other programming languages. - Additional built-in sensors: One of them is a digital microphone created by the Pulse Density Modulation Module (PDM) on the nRF52840 chip. It can receive real-time audio data, allowing it to be used for audio detection. The board not only receives audio data, but can also talk through the MSM261D3526H1CPM microphone. The other is a 6-axis inertia measurement unit (IMU), which can be applied in TinyML projects such as gesture recognition. - ULTRA SMALL SIZE - 21 x 1.8cm, Seeed Xiao series classic form factor for portable devices.
