Yotaphone 2 Smartphone Features an Improved AMOLED + ePaper Dual Display

About two years ago, Yota , a technology company based on Russia, introduced the Yotaphone, an Android smartphone with an innovative dual display solution comprised of a standard color display on the front, and an E-ink display on the back, in order to extend battery life. The idea was interesting, but the phone did not look that great. But with Yotaphone 2, the company upgraded the processor with a Snapdragon 800 processor, a larger 5″ display, and if the back ePaper display looks as crisp and clear in real life as in the picture below, you could have a winner, and copycats will eventually show up. Yotaphone 2 specifications: SoC – Qualcomm Snapdragon 800 quad-core Krait processor @ 2.2 GHz with Adreno System Memory – 2GB RAM Storage – 32GB eMMC Displays Front – 5″ AMOLED touch screen, 1920×1080 resolution,16M colors, 442ppi, with Corning Gorilla glass 3. Rear – 4.7”  […]

LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller

LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]
