Seeed XIAO nRF52840 Plus
€13.40
Description
Seeed Studio XIAO nRF52840 Plus, powered by Nordic chipset with FPU, brings more SMD pins to our popular Bluetooth-enabled board. While maintaining all the capabilities of the standard version including Bluetooth 5.0, NFC, and low power consumption, this Plus variant features redesigned castellations and pad layout on the back, offering 9 additional GPIOs specifically for advanced Bluetooth projects requiring expanded I/Os via SMD board-to-board soldering.
Please note Seeed Studio XIAO Plus doesn‘t come with 7-pin headers as it's designed for SMD board-to-board soldering.
- 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 with 2.54mm pin headers, 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).
