The Adafruit SHARP Memory Display Breakout features a 1.3" 168×144 monochrome LCD that combines the ultra-low power consumption of e-paper with the fast refresh rates of a traditional LCD. The display shows crisp black pixels on a grey background, giving a pleasant e-reader appearance that's excellent in daylight.
The bare display is mounted on a breakout board with a 3 V regulator and level shifting, making it compatible with both 3 V and 5 V power and logic. Communication requires only 3 SPI pins (write-only), but the entire 168×144 pixel framebuffer (~3 KB) must be stored in the microcontroller's RAM.
Key Features
- 1.3" 168×144 Monochrome Display – Black-on-grey, e-reader style appearance
- Ultra-Low Power – E-paper-like power consumption with LCD-like refresh speed
- Daylight Readable – No backlight, but highly visible in ambient light
- SPI Interface – Write-only, requires only 3 data pins
- 3 V / 5 V Compatible – Onboard regulator and level shifting
- ZIF Socket Mounting – Display connects via ZIF socket with double-sided tape adhesion
- 4 Mounting Holes – Easy to attach to enclosures
Ideal For
- Low-power status displays and dashboards
- Outdoor-readable information panels
- Battery-powered wearable displays
- E-reader style interfaces

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- ESP32
- ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
