Product Description:

Seeed Studio XIAO nRF52840 has an ultra-low power consumption of only 5 μA in the deep sleep mode, the embedded BQ25101 chip supports battery charge management which prolongs its use time. Moreover, Seeed Studio XIAO nRF52840 supports the USB Type-C interface which can supply power and download code. It also has rich On-chip Memory of 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 it perfect for machine learning applications.

Notes:

All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged.
