Product details

The Heltec E-Ink Display 2.13 Inch Vision Master ESP32-S3 LoRa is a compact IoT development board featuring an integrated E-Paper display and a radio module for the LoRa frequency range of 863–870 MHz. It combines the energy-efficient display technology of a 2.13″ E-Ink display with the versatile communication capabilities of the ESP32-S3 microcontroller, which supports both Wi-Fi and Bluetooth Low Energy. The device is optimized for extremely low power operation: the display can hold content for up to 180 days without power, while the deep sleep mode reduces consumption to just a few microamperes. With integrated battery management, expandable interfaces, and a robust design, the board is suitable for battery-operated sensor nodes, Meshtastic setups, smart home displays, or outdoor IoT projects.
