Hardware design

Inkplate 5V2 is an open-source product, so its full hardware design is out in the open. On the following pages you'll find schematics, KiCad design files, and other technical details about the hardware, whether you want to modify the board, troubleshoot it, or just see how it works inside.

Basic overview

Inkplate 5V2 has a 5.17-inch e-paper display, USB-C for both power and programming, and plenty of GPIO pins with I2C, SPI, and a Qwiic header. The onboard ESP32 handles Wi-Fi and Bluetooth, the CH340C bridges USB to UART, and there's a microSD slot for storage. Power management runs on a mix of TI ICs for the e-paper supply and regulation (which also handles temperature sensing through a built-in NTC input) and a Microchip charger IC for the battery.

E-paper panel

The ED052TC4 is a 5.17-inch e-paper display panel from E Ink Holdings Inc. This model comes without a frontlight or touchscreen, which suits low-power, high-contrast uses such as e-book readers.

It has a 720 × 1280 resolution and a reflective matte treatment, and supports 3-bit grayscale. The display operates in a 0°C to 50°C temperature range and can be stored in temperatures as low as -25°C.

ℹ️
The 720 × 1280 figure is the panel's native portrait orientation. The Inkplate library uses the display in landscape by default, so in your sketches the canvas is 1280 pixels wide and 720 pixels tall. Use setRotation() if you want portrait.
