Overview
The LILYGO Mini E-Paper Core is a miniature development board built around a 1.02-inch e-paper display, designed with a focus on low power consumption and a compact ABS shell enclosure. Its small footprint makes it ideal for wearable displays, sensor tags, and always-on information displays where battery life is critical.
Three variants are available: an ESP32-S3 base version (H676, $19.10), a CC1101 433MHz version (H627, $12.60), and a CC1101 868MHz version (H585, $12.70). The CC1101 variants add sub-GHz radio connectivity for long-range, low-bandwidth communication. USB connectivity and TF card support require the optional T-U2T module, and a battery is sold separately.
Firmware Compatibility
The Mini E-Paper Core supports Arduino IDE and ESP-IDF. E-paper libraries for the 1.02-inch panel and CC1101 radio libraries are available in the GitHub repository at LilyGO-Mini-Epaper.
Flashing Guide
- Obtain a T-U2T USB-to-UART adapter for flashing.
- Connect the T-U2T to the Mini E-Paper Core's programming interface.
- Install the appropriate Arduino core (ESP32 or ESP32-S3).
- Select the matching board in Arduino IDE.
- Upload your sketch via the T-U2T adapter.
