Product Description

Inkplate 4 TEMPERA is an easy-to-use, all-in-one device that puts the power of e-paper technology in the palm of your hand. Behind its 3.8-inch, 600×600-pixel e-paper touchscreen, it packs the following features into one compact, elegant package: frontlighting, an abundance of sensors, Wi-Fi and Bluetooth connectivity, a built-in battery, and a low-power operating mode.


In this digital age, screens are the windows through which we interact with much of our world, and e-paper technology addresses many of the challenges posed by conventional screens. More specifically, they offer high contrast, daylight readability, and unparalleled energy efficiency. And there is one more thing that sets our screens apart: sustainability. Every Inkplate 4 TEMPERA gives new life to an ED038TH2 E Ink display that we’ve rescued from a tragic future as e-waste. We’d rather see these screens in your hands than in a landfill.


Inkplate 4 TEMPERA is powered by the ESP32 microcontroller, to which we’ve added all of the peripherals we thought you might find useful. Inside the enclosure is a 1200-mAh battery and power-management circuitry so you can charge it easily and determine its remaining charge accurately. Inkplate 4 TEMPERA’s real-time clock (RTC) allows for precise time measurements, and its microSD card slot allows you to to store and display images, among other applications. If you’re looking for sensors, you’ll find a gyroscope and an accelerometer, as well as temperature, humidity, air quality, and gesture sensors. Inkplate 4 TEMPERA also has a built-in, frequency-adjustable buzzer. And of course, it includes various GPIO pins that support peripheral connectivity through a GPIO expander or via the easyC ecosystem.


So, if you’re in the market for a nice-looking screen on which you can display whatever you want—wherever, at whatever time of day, and for however long you want—we invite you to check out Inkplate 4 TEMPERA. We think you’ll find it delightful!
