The NULA Core is a compact ATmega328 development board with USB-C, Li-ion battery charging, Qwiic connectivity, and full Arduino compatibility, making it an excellent choice for learning electronics, prototyping, and portable embedded projects.
Introducing the Inkplate 5 Gen2, a versatile board compatible with Arduino and MicroPython platforms, featuring a recycled 5.2" E-Ink (e-paper) display with fast refresh times of just 0.22 seconds. This fully open, plug-and-play device, powered by the ESP32 microcontroller, is designed for effortless internet connectivity via Wi-Fi or with other devices via Bluetooth.
Its energy-efficient design allows for ultra-low power consumption, enabling it to operate for months on a single charge of a Li-ion battery. The Inkplate 5Gen2 is not only about power and connectivity; it's also about convenience. The built-in microSD slot (microSD card not included) and real-time clock provide unlimited data storage possibilities and precise timekeeping. The device even features numerous GPIO pins, allowing easy expansion of your projects with almost any peripheral device. A USB-C to USB-C cable is included in the package, so you can start using it right out of the box.
Designed for high-performance embedded development, the Inkplate 5Gen2 fully supports Espressif's official ESP-IDF framework. This native environment grants developers low-level control over the hardware, enabling precise memory management, optimized display rendering routines, and custom power profiling to take full advantage of the board's ultra-low deep sleep capabilities.
The e-paper display of the Inkplate 5Gen2 offers visual delight. It provides a beautiful, sharp image under all conditions, including direct sunlight. The display resolution is 1280x720 pixels, in monochromatic mode, supporting black, white, and 6 shades of grey. The most interesting part? The E-Ink display requires no power between screen updates.
The Inkplate 5Gen2 refreshes at a speed of 0.99s for a full refresh and 0.22s for a partial refresh.
Our device is a fantastic starting point for those wanting to experiment with E-Ink technology, all neatly packaged in a compact board.
MicroSD card, CR2032 battery, LiPo battery and case not included.
