FoBE Quill ESP32S3 Mesh
A development kit featuring the ESP32-S3 SoC and an integrated SX1262 LoRa® transceiver.

Introduction
The FoBE Quill ESP32S3 Mesh is a compact and feature-rich IoT development platform, integrating Espressif's high-performance multi-protocol SoC ESP32-S3 and Semtech's ultra-low-power sub-GHz radio transceiver SX1262. Designed for IoT applications, it provides a comprehensive wireless connectivity solution supporting IEEE 802.11 b/g/n Wi-Fi, Bluetooth 5, Thread, Zigbee, and LoRa®.
This development board features efficient battery charging management, discrete power path, ultra-low quiescent current DC-DC converter, a 1.3-inch monochrome OLED display (SSD1306 compatible), user-programmable LED and button, MFP expansion connector, reversible USB-C connector, and easy-to-expand pin headers, making it ideal for rapid prototyping and development.
