FoBE Quill nRF52840 Mesh
A development kit featuring the nRF52840 SoC and an integrated SX1262 LoRa® transceiver.
Introduction
The FoBE Quill nRF52840 Mesh is a compact and versatile development platform for IoT solutions. It combines Nordic's high-end multiprotocol SoC, the nRF52840, with Semtech's ultra-low-power sub-GHz radio transceiver, the SX1262 (packaged using SiP technology). Designed for IoT applications, it offers a comprehensive wireless connectivity solution, supporting protocols such as Bluetooth 5, Thread, Zigbee, IEEE 80.2.15.4, and LoRa®.
This development board is feature-rich, including a battery charger, dedicated power path management, an ultra-low quiescent current DC-DC converter, a 1.14-inch color IPS display, user-programmable LEDs and buttons, an MFP expansion connector, a reversible USB-C connector, and header sockets for easy expansion.
