Note:
- High-Performance MCU: Nordic Semiconductor‘s nRF52840 chip with FPU at 64 MHz, multiple development ports, compatible with Arduino/CircuitPython/MicroPython
- Advanced Wireless Connectivity: Bluetooth 5.0 with built-in antenna and NFC support
- Efficient Power Management: 5 μA deep sleep consumption with integrated Li-ion battery charging
- Expanded 20 GPIOs: 9 extra 1.27mm pitch SMD castellation pins beyond standard XIAO nRF52840
- Universal Compatibility: Standard backside layout (with aligned battery pads, and debugger pads) for more to-be-released XIAO expansion boards
- Classic XIAO Form Factor: 21 x 17.8mm design, single-sided mounting for wearables and space-constrained projects
- XIAO Accessory Add-ons Compatibility: Natively compatible with all the XIAO accessory add-ons of expansion, connectivity modules (LoRa, CAN_Bus, RS-485), sensors (2-Mic Array, Vision AI, mmWave Motion, Environmental sensing), and actuators (ePaper display, LED Matrix, relay and more).
As a new addition to the Seeed Studio XIAO family, the XIAO nRF52840 Plus remains the classic XIAO design (thumb-size, SMD, stamp holes). All these features make it a perfect fit for either space-limited applications, or a production-ready System on Module (SoM) for your PCBA designs. (check out our Fusion Co-Create one-stop prototyping, producing and promoting services to explore how to scale up your XIAO-based designs).
