Seeed Studio XIAO BLE Nordic nRF52840 for Arduino/MicroPython/CircuitPython, Bluetooth 5.0 NFC and ZigBee with Onboard Antenna Machine Learning
Seeed Studio XIAO BLE Nordic nRF52840 for Arduino/MicroPython/CircuitPython, Bluetooth 5.0 NFC and ZigBee with Onboard Antenna Machine Learning
As the first wireless product in the Seeed XIAO family, Seeed XIAO BLE has equipped a powerful MCU Nordic nRF52840 designed in a Bluetooth 5.0 module and based on a 32-bit ARM Cortex M4 CPU with floating-point unit (FPU) that operates at 64 MHz. With the ability to connect wirelessly, it remains the classic form factor of the Seeed XIAO series, small and exquisite, which can be used for portable devices and Internet of Things projects. In addition, it consumes only 5μA in deep sleep mode and supports battery charge management through the BQ25101 chip. To better support IoT and TinyML AI projects, there is an expanded version "Seeed XIAO BLE Sense", which includes 6-axis IMU and PDM microphones. Compared 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 small and elegant reset button on one side of the Type-C interface. On the other hand, it is equipped with a three-in-one LED along with a power LED. There are 11 digital I/O which can be used as PWM pins and 6 analog I/O pins that can be used as ADC pins. Supports UART, IIC and SPI on the three popular serial ports. Just like Seeed XIAO RP2040, it has built-in flash memory of 2MB, which means it can also be programmed with Arduino, MicroPython, CircuitPython or other programming languages.
Product Features
- POWERFUL CPU: As the first wireless product in the Seeed XIAO family, the seeed studio XIAO nRF52840 has equipped a powerful Nordic nRF52840 MCU designed in a Bluetooth 5.0 module, built around a 32-bit ARM Cortex-M4 CPU with floating-point unit (FPU) that operates at 64MHz. e.g.
- Wireless capabilities: XIAO nRF52840 has an NFC module Bluetooth 5.0 with a built-in antenna. With the wireless connectivity capabilities, it stays with the classic form factor of the Seeed XIAO series: small and exquisite, ideal for portable devices and Internet of Things projects.
- Refined Interface: First, the near-field communication (NFC) on the board is functional. Secondly, there is a small and elegant reset button on one side of the Type-C interface. On the other hand, it is equipped with a three-in-one LED along with power LEDs. Supports UART, IIC and SPI on all three popular serial ports. Just like the Seeed XIAO RP2040, it has built-in flash memory of 2MB, which means it can also be programmed with Arduino, MicroPython, CircuitPython or other programming languages.
