Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".
Seeed Studio XIAO nRF52840 is carrying wireless capability for the first time and it supports Bluetooth 5.0, also able to operate withlow power consumption. It will be your best microcontroller for Bluetooth applications.
Features
Versatile Microcontroller:Incorporate theNordic nRF52840chip with FPU, operating up to 64 MHz, mounted multiple development ports, supported by Arduino / CircuitPython
Wireless Capabilities:Implement Bluetooth 5.0, BLE functions with onboard antenna, also provide NFC connectivity
Elaborate Power Design: Provideultra-low power consumptionas 5 μA in deep sleep mode while supporting lithiumbattery charge management
Thumb-sized Design:21 x 17.5mm, Seeed Studio XIAO series classic form-factor, suitable for wearable devices
Perfect for Production:Breadboard-friendly & SMD design, no components on the back
Seeed Studio XIAO nRF52840 has anultra-low power consumptionof only 5 μA in the deep sleep mode, the embedded BQ25101 chip supports battery charge management whichprolongs its use time. Moreover, Seeed Studio XIAO nRF52840 supports the USB Type-C interface which can supply power and download code. It also hasrich On-chip Memoryof 1 MB flash and 256 kB RAM, and an Onboard Memory of 2 MB QSPI flash. 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. 1 Reset button, 1 3-in-one LED, 1 Charge LED, and 1 Bluetooth antenna are on board, allowing developers to debug their code very easily.
The powerful performance makes itperfect for machine learning applications, and the tiny size allows it to be used in wearable devices and Internet of Things projects, not just for prototypes but the mass production. Furthermore, Seeed Studio XIAO nRF52840 is friendly to the communities for itsstrong software compatibilities, which support Arduino, Micropython, and CircuitPython. Except for the software, flexible I/O allows it to speak to almost any external device.
