Note: This is the Heltec Wireless Paper (US Band 902-928 MHz) with Meshtastic firmware pre-installed. It includes the LoRa antenna and acrylic protection board. Perfect for compact Meshtastic nodes, electronic shelf labels, price tags, and low-power E-Ink display projects. The Wireless Paper is an ultra-low-power ESP32-S3 based E-Ink development board with multi-wireless support. It features a 2.13-inch black & white E-Ink display that remains visible for up to 180 days after power loss, making it ideal for long-term, battery-powered applications such as smart labels, asset tracking, environmental monitors, and Meshtastic mesh networking nodes. KEY FEATURES 2.13-inch E-Ink Display: 250 × 122 pixels, high contrast, high reflectance, ultra-wide viewing angle, and partial refresh support. ESP32-S3FN8 MCU: Powerful dual-core processor with Wi-Fi and Bluetooth 5 support. LoRa Connectivity: SX1262 transceiver (US 902-928 MHz band) with external LoRa antenna for long-range communication. Ultra-Low Power: Only ~20 µA in deep sleep — excellent for long-lasting battery or solar-powered use. Easy Image Refresh: Drag-and-drop BMP support for simple display updates. Onboard USB-UART Bridge: Convenient for firmware updates, debugging, and secondary development. Acrylic Protection Board: Included for basic physical protection of the board.
