M5Stack Core2 display: specs, driver revisions & setup
M5Stack's 2.0-inch 320×240 IPS development kit. The display controller is listed as ILI9342C, with ILI9342E on newer documentation, and touch is an FT6336U capacitive controller.

Which M5Stack Core2 revision do you have?
Known display configuration for this board.
| Revision | Driver IC | How to identify | Library settings |
|---|---|---|---|
| Core2 (v1.0 / v1.1 / v1.3) | ILI9342C / ILI9342E | v1.3 changes the IMU, not the display | M5Unified / M5GFX auto-detect; LovyanGFX Panel_ILI9342 |
Same display spec for volume production
Prototyped on the M5Stack Core2? These modules from our direct factories share the panel size and resolution, come with a datasheet and a fixed driver IC per production lot, and are available from 1 pc samples. MOQ and lead time are agreed per project.
From M5Stack Core2 prototype to production
Dev boards are ideal for proving a UI, but their panels are bought on the open market: the controller can change between batches, there is rarely a datasheet, and lifetime is not guaranteed. For a product, specify a module with a fixed driver IC per production lot, a datasheet and a lifecycle commitment.
Our direct factories build modules with the same 2″ 320×240 format. Same 2.0-inch 320×240 size and ILI9342C controller; our modules use an RGB interface, so check the bus your host provides. Samples start at 1 pc; MOQ and lead time are agreed per project with our sales team.
Before you debug code
- Confirm which revision you have (table above): driver IC changes are the most common cause of a white screen.
- Check the backlight pin is not reused in your sketch.
- Change one setting at a time (driver, inversion, colour order), and keep a known-good example to compare against.
Configuration examples
#include <M5Unified.h>
void setup() {
auto cfg = M5.config();
M5.begin(cfg); // configures display, touch and AXP192
M5.Display.setTextSize(2);
M5.Display.println("Hello Core2");
}
void loop() {
M5.update();
}Frequently asked questions
Which display driver does the M5Stack Core2 use?
ILI9342C, with ILI9342E listed on newer documentation; both are handled by M5GFX/M5Unified.
