Description ▼
Note: This is the Heltec Vision Master E213 (US Band 863-928 MHz) with Meshtastic firmware pre-installed. It includes the LoRa module and LoRa antenna. Perfect for compact Meshtastic mesh networking nodes with its E-Ink display.
The Vision Master E213 is a compact, ultra-low-power ESP32-S3 based E-Ink LoRa development board. It features a 2.13-inch black & white E-Ink display that is sunlight-readable and can retain the last image for up to 180 days after power loss — making it ideal for long-term, battery-powered deployments.
This unit comes with the US frequency band (863-928 MHz), the LoRa module enabled, the matching LoRa antenna, and Meshtastic firmware pre-loaded — ready for immediate use in Meshtastic mesh networks. Great for off-grid communication, asset tracking, electronic shelf labels, environmental monitoring, and other low-power IoT projects.
KEY FEATURES
- 2.13-inch E-Ink Display: 250 × 122 pixels, black & white with partial refresh support — ultra-low power and excellent readability in sunlight.
- ESP32-S3R8 MCU: Dual-core processor with Wi-Fi and Bluetooth 5 support.
- LoRa Connectivity: SX1262 LoRa transceiver (US 863-928 MHz band) with up to 21 dBm TX power — includes external LoRa antenna.
- Pre-flashed with Meshtastic Firmware: Ready for Meshtastic mesh networking right out of the box.
- Ultra-Low Power: Only ~20 µA in deep sleep — perfect for long-lasting battery or solar-powered nodes.
- Battery Management: Onboard charging circuit with USB-C, overcharge protection, and automatic power switching.
- Expansion Options: Dual SH2.0-4P sensor interfaces (QuickLink compatible), 2×18 pin headers, and IPEX antenna connectors.
- Compact & Lightweight: Small form factor for portable or embedded projects.
