3.97" touch e-paper display and ESP32-S3
M5Stack PaperMono Lite is an ESP32-S3R8 development module with a 3.97" touch e-paper display and a backlight. The display has a resolution of 480 x 800 px, and the housing also contains a microphone, a buzzer, a motion sensor, an RTC clock and a microSD card slot.
Compared to the PaperMono version, the Lite model has no NFC and LoRa modules, while the e-paper display and 2.4 GHz Wi-Fi stay the same. The built-in 1150 mAh battery and the M5PM1 power management chip let you build a portable low-power device on it, e.g. a reader. You can find the other modules of this family among the M5Stack controllers.

E-paper display with touch and backlight
The 3.97" display with the SSD1677 chip has a resolution of 480 x 800 px and shows 4 grayscale levels. The touch panel with the FT6336G controller detects touch from 5 px to 475 px horizontally and from 5 px to 795 px vertically, because the firmware narrows the edges.
The integrated backlight lets you read text and use the menu even in low light, and the brightness is set by the M5PM1 chip. The driving waveforms are stored in the display's OTP memory, so your program can use them without its own image refresh configuration.
ESP32-S3R8, sensors and sound
- ESP32-S3R8 microcontroller: two Xtensa LX7 cores up to 240 MHz and 2.4 GHz Wi-Fi
- Memory: 16 MB Flash, 8 MB Octal PSRAM and a microSD card slot for data and files, which fits e.g. the Goodram All in One card
- BMI270 motion sensor: 6-axis, with an interrupt that can wake the device
- RX8130CE RTC clock: keeps time and can wake the device from sleep mode
- Sound: LMD4737T261-AC02 PDM microphone and a built-in buzzer for signals
- Signaling: RGB LED on the side of the housing and two user buttons

Battery and power management
The module is powered by a built-in 1150 mAh battery, which you charge through the USB type-C connector with 5 V. For charging and uploading a program you will need a USB type-A - USB type-C cable, e.g. the Akyga with backlight. The M5PM1 chip manages power across several operating levels, and the M5IOE1 pin expander separately switches the power of the display, touch panel, microphone and microSD card on and off.
A single press of the power button turns the module on or resets it, and a double press turns it off. If you hold the button for about 2 s, until the red LED starts blinking, the module enters download mode, and you upload new software from your computer over USB.
Arduino, UiFlow2, ESP-IDF and an e-book reader
You can program the module in the Arduino IDE with the M5Unified, M5GFX, M5PM1 and M5IOE1 libraries, in the graphical UiFlow2 environment or in ESP-IDF. The manufacturer also provides a ready-made PlatformIO configuration for a board with 16 MB Flash and PSRAM.
The CrossPoint E-Reader firmware was created for PaperMono Lite, and it turns the module into an e-book reader. Programming instructions, libraries and examples are described in the manufacturer's documentation, and the factory firmware code is in the GitHub repository.
The module can work as an e-book reader with CrossPoint firmware
Is it the right choice for you?
A good choice if:
- You are building your own e-book reader or a portable terminal with an e-paper display
- You need a display that is readable in low light thanks to the backlight
- You are creating a battery-powered IoT device with Wi-Fi connectivity
Consider another option if:
- You need NFC and LoRa modules in the same device: PaperMono - M5Stack C153
- You want a color e-paper with ESP32-S3: M5Paper Color - M5Stack C151

Did you know?
From 0.07 s to 4.71 s per refresh
In the manufacturer's tests, the epd_fastest mode of the M5GFX library refreshes the display in 0.07 s, and the highest-quality epd_quality mode in 4.71 s, which is more than 60 times longer.
Frequently asked questions
How does PaperMono Lite differ from the PaperMono version?
The Lite version has no NFC and LoRa modules and has a white enclosure. The ESP32-S3R8, display, sensors and 1150 mAh battery are the same in both.
How often does PaperMono Lite need a full refresh?
After about 10 fast partial refreshes, as the manufacturer recommends. A full refresh removes the ghosting that builds up when the image changes.
How do I turn the PaperMono Lite module on and off?
A single press of the power button turns the module on or resets it, and a double press turns it off. Holding it for about 2 s starts firmware download mode.
Can PaperMono Lite work as an e-book reader?
Yes. The manufacturer provides CrossPoint E-Reader firmware for PaperMono Lite, and the integrated display backlight makes reading easier in low ambient light.
In which environments can you program PaperMono Lite?
In the Arduino IDE, UiFlow2 and ESP-IDF. A ready PlatformIO configuration is also provided.
