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 Low Energy 5.4, 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.

Feature

Inspired by the unique SMD pins design of the RICK TNY, we're now introducing the Seeed Studio XIAO Plus boards (available in XIAO nRF52840 Plus, XIAO nRF52840 Sense Plus, and XIAO ESP32-S3 Plus) to include an updated design of more castellations and a new pad layout on the back.

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 Low Energy 5.4 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).
