Overview

About ESP32-2432S028R Yellow Display (CYD) 2.8 inch Touch.

The ESP32-2432S028R, universally nicknamed the 'Cheap Yellow Display' (CYD), is an all-in-one development board that combines an ESP32 microcontroller with a 2.8 inch 240x320 ILI9341 color TFT, a resistive touch panel and a microSD slot on a single yellow PCB. Because everything is pre-wired, it removes the fiddly job of connecting a separate display, touch controller and MCU.

With the ESP32 onboard you get 2.4GHz WiFi and Bluetooth, plenty of flash and RAM, and USB for programming, so it is ready to build touch HMIs, IoT dashboards and standalone gadgets straight out of the box. The 2.8 inch ILI9341 screen is driven over SPI and the resistive touch is read by an XPT2046 controller, both of which have excellent library support.

The CYD has become a trending favourite in the maker community because it is genuinely inexpensive for what it offers and works beautifully with TFT_eSPI, LVGL and ESPHome. At around Rs 1600 it is a compelling all-in-one platform for anyone who wants a WiFi-connected touchscreen without wiring a thing.

Buying guide

How to choose.

Buy the CYD when you want a single board that already integrates the ESP32, a 2.8 inch color touch display and storage, so you can go straight to writing UI code. It is the fastest path to a WiFi touchscreen gadget and pairs perfectly with LVGL for polished interfaces or ESPHome for Home Assistant projects.

If you prefer to keep your microcontroller separate or already own an ESP32/Arduino, a standalone display like the 2.4 inch ILI9341 module (BOTBIT-DSP-09) may suit you better. But for convenience and value, the all-in-one CYD is hard to beat.

For programming, use the Arduino IDE or PlatformIO with the TFT_eSPI library configured for the ESP32-2432S028R pin mapping, and add the XPT2046 touch setup. Community User_Setup files for the CYD are widely available, which makes getting started quick.

FAQ

Common questions.

Do I need to wire anything to use the display and touch?

No. The CYD integrates the ESP32, 2.8 inch ILI9341 display, XPT2046 touch and microSD slot on one board, all pre-wired. You just connect USB, load firmware and start coding the UI.

How do I program it?

Use the Arduino IDE, PlatformIO or ESP-IDF over USB. For graphics, configure TFT_eSPI with the CYD (ESP32-2432S028R) pin mapping; ready-made User_Setup files and LVGL examples are widely shared by the community.

Is the touch capacitive or resistive?

The standard ESP32-2432S028R uses a resistive touch panel read by an XPT2046 controller. It responds to firm presses from a fingertip or stylus and benefits from a one-time calibration in software.

Does it have WiFi and Bluetooth?

Yes. The onboard ESP32 provides 2.4GHz WiFi (802.11 b/g/n) and Bluetooth, so you can build connected dashboards, pull data from the internet or integrate with Home Assistant via ESPHome.

Does it work with ESPHome and LVGL?

Yes. The CYD is popular precisely because it works well with LVGL for rich touch UIs and with ESPHome for Home Assistant integrations, thanks to strong community support and example configs.

What comes in the box and how is it powered?

You get the ESP32-2432S028R board itself, powered and programmed over USB (5V). A USB cable and any enclosure are typically not included, so add a data-capable USB cable to your order.
