LILYGO’s New Mini E-Paper Core Features an ESP32-S3 MCU

LILYGO has recently introduced the Mini E-Paper Core ESP32, an ESP32-S3-based E-paper display module that is compatible with different LILYGO shields like the nRF24L01 2.4GHz wireless and 433/868 MHz LoRa.

Over the years LILYGO has introduced many display products like the T-Display-S3 Amoled, T-Display-S3-Long, T-Display-S3-pro, and LILYGO T-HMI. For those interested, further information on these products is available for review.

LILYGO Mini E-Paper Core S3 Features:

• System-on-Chip & CPU: Espressif Systems ESP32-S3FN4R2, featuring a dual-core Tensilica LX7 processor capable of speeds up to 240 MHz and equipped with AI vector instructions.
• Memory: 512KB RAM, 2MB PSRAM.
• Storage: 4MB flash, plus a MicroSD card slot.
• Display: 1.02-inch e-paper with a resolution of 128×80.
• Connectivity:
  • WiFi 4 (2.4 GHz) and Bluetooth.
  • USB Type-C for power and programming.
• Expansion Interfaces:
  • 7-pin header: GPIOs, ADCs, 3.3V, GND.
  • 8-pin header: GPIOs, SPI, ADC, 5V, VBUS, VBat, GND.
• Additional Features:
  • Triple-toggle button and reset button.
• Power Supply:
  • USB-C (5V).
  • The external battery is compatible with the charging circuit.
• Power Consumption: Approximately 10uA in sleep mode.
• Enclosure: Supports a 3D-printed shell.

LILYGO offers a T-U2T USB to TTL converter for programming but as my understanding goes, you don’t need this programmer to upload the code it can be done through the USB.

For programming the device LILYGO supports both PlatformIO and Arduino, with resources like instructions and firmware available on a shared GitHub repository. You’ll just need to select the “ESP32S3 Dev Module” board, “UART0 / Hardware CDC” upload mode, and “Hardware CDC and JTAG” USB mode.

The company provides additional connectivity options with an nRF24L01 2.4GHz shield and a 433 MHz LoRa shield.

Available on Aliexpress, the ESP32-S3 LILYGO Mini E-Paper Core is priced at $22.98 including shipping. Additional accessories like the nRF24L01 2.4 GHz shield and the CC1101 433/868 MHz shield are also offered at $12.98 and $16.98, respectively
