Heltec ESP32-S3 Wireless Paper E-Ink 2.13 Inch | SX1262, LoRa WiFi Bluetooth, 20uA Deep Sleep, Low Power IoT Node for Meshtastic
- ULTRA-LOW POWER & 180-DAY RETENTION: Powered by the ESP32-S3FN8 chipset, this E-Ink development kit consumes only 20uA in deep sleep mode. The 2.13-inch black-and-white display (250x122 pixels) features bi-stable technology, maintaining images for up to 180 days after a power outage, making it the perfect solution for energy-critical IoT applications.
- TRIPLE-MODE WIRELESS CONNECTIVITY: Experience seamless communication with integrated Wi-Fi, Bluetooth (BLE), and SX1262 LoRa support. Supporting the 863-928MHz frequency range, it is fully compatible with Meshtastic for building decentralized mesh networks and remote monitoring systems.
- EFFORTLESS BMP IMAGE REFRESH: Say goodbye to complex coding for simple updates. Our board features an internally integrated display refresh functionsimply drag and drop BMP images to update the screen. Ideal for rapid prototyping of identity tags, smart price labels, and real-time status monitors.
- DEVELOPER-FRIENDLY INTERFACE: Equipped with a universal USB Type-C interface for power supply, firmware downloads, and debugging. The onboard USB-UART bridge and included SH1.25 x 2 battery connector facilitate secondary development, while the transparent acrylic plate provides essential protection for your hardware.
