LilyGo has introduced a new developer board featuring a 4.7-inch E Ink capacitive touchscreen with a resolution of 960 x 540. Like most E Ink displays, this one is designed for easy reading in bright sunlight. While it doesn't support colors, it can show 16 shades of grey. The purpose of using an E Ink display is to achieve lower power usage compared to traditional screens.
Technical Specs
This device is powered by an ESP32-S3 chip, which means it’s not able to run a desktop OS like Windows. Instead, the T5 E-Paper S3 Pro is tailored for programming platforms such as VS Code and Arduino IDE. It includes 16 MB of flash memory, along with 8 MB of PSRAM. Users can also take advantage of a memory card for additional storage.
Connectivity Options
The board supports wireless communication not just through WiFi in the 2.4 GHz range and Bluetooth 5, but also through LoRa technology, enabling long-distance data transmission. This feature is particularly useful for IoT devices that typically transmit small amounts of data. Finally, the T5 E-Paper S3 Pro has dimensions of 129 x 69 x 11 mm (LxWxH) and supports MagSafe-compatible wireless charging.
LILYGO is currently listing the price at $73.06, but the unit is out of stock at the moment. For those who seek a more affordable option, the Vision Master E213 on Amazon could be a good alternative.
