Embedded electronics specialist LILYGO has launched an upgraded model of its Mini E-Paper Core all-in-one improvement board, which is now based mostly across the Espressif ESP32-S3 microcontroller — offering extra reminiscence, extra flash, and vector directions for sooner on-device machine studying and synthetic intelligence (ML and AI) workloads.
“The design focuses on low energy consumption and the essential necessities of MINI look to maintain the product look as [small] as attainable,” LILYGO explains of its board, which launched in its unique model again in 2021. “The Mini [E-Paper Core] is predicated on the 1.02-inch ePaper display dimension, and the ABS shell is designed based mostly on this mini construction to maintain the whole module mini.”
The unique Mini E-Paper Core is now joined by a variant which swaps out the unique Espressif ESP32-PICO-D4 microcontroller for the newer Espressif ESP32-S3, as delivered to our consideration by CNX Software program. Which means a shift from a dual-core Tensilica Xtensa LX6 CPU to the newer LX7, bringing with it vector instruction extensions for sooner on-device AI and ML workloads, 512kB of static RAM (SRAM) plus 2MB of pseudo-static RAM (PSRAM), and a lift to 4MB of flash storage.

What hasn’t modified is the show on the entrance of the system, a 128×80 electrophoretic ePaper panel which solely requires energy when it is altering states. The rear of the gadget contains pin headers for unused general-purpose enter/output (GPIO) pins, together with 5 related to the microcontroller’s analog to digital converter (ADC) — although these come on the lack of the unique design’s two digital to analog converter (DAC) pins. There is a three-way button on the highest, and help for single-band 2.4GHz Wi-Fi 4 and Bluetooth 5 Low Power (BLE).
The brand new Mini E-Paper Core S3 is now accessible on the LILYGO retailer at $19.10 per unit, sharing a list with the unique design — so you’ll want to choose the “ESP32 S3 [H676]” model within the drop-down record earlier than ordering in case you do not need to obtain the older, and oddly costlier, unique model.
