ESP32-S3 Board with a 1.69'' Touchscreen
ESP32-S3-Touch-LCD-1.69 is a development board with a 1.69'' touchscreen with a resolution of 240 x 280 px. It also features a 6-axis motion sensor, an RTC clock and a battery charging circuit. The manufacturer designed it for quickly building devices with a touch interface.
The board is built around the ESP32-S3R8 with two Xtensa LX7 cores up to 240 MHz, 2.4 GHz Wi-Fi and Bluetooth 5 (LE), 8 MB of PSRAM and 16 MB of Flash. The screen with the ST7789V2 controller uses SPI and the CST816T touch panel I2C, so more pins stay free.

Motion Sensor, RTC Clock and Buttons
The QMI8658 sensor combines a 3-axis accelerometer and gyroscope, so you can use it to detect gestures and count steps. You can connect a backup battery to the PCF85063 clock via the SH1.0 connector.
- PWR: programmable button, recognizes single, double and long presses
- BOOT and RST: buttons for program upload mode and restart
- Buzzer: audio signaling controlled from the program
Battery Power and Pinout
You can connect a 3.7 V lithium battery to the MX1.25 connector, and the ETA6098 chip handles its charging and discharging. Check the battery voltage through a divider on pin GPIO1.
Sensors and modules can be soldered to the pads on the board edge. 5 V and 3.3 V power, the I2C bus, UART and pins GPIO2, GPIO3, GPIO17 and GPIO18 are brought out there.

1.69'' Screen and Arduino and ESP-IDF Examples
The 1.69'' 240 x 280 px color screen displays 262k colors. The manufacturer states that the touch panel has good light transmission, responds quickly and is durable.
To get started, you have examples for Arduino IDE and ESP-IDF: graphics, the RTC clock, reading the motion sensor in the LVGL interface, button handling and lithium battery voltage measurement.
Is It the Right Choice for You?
A good choice if:
- You are building a wearable device prototype with a touchscreen
- You need a motion sensor and an RTC clock on one small board
- You want to power your project from a 3.7 V lithium battery
Consider another option if:
- You prefer a larger round 480 x 480 px screen with microSD: ESP32-S3-Touch-LCD-2.1B
- You need a large 7'' 800 x 480 px screen for an HMI panel: Waveshare 27078
Fun Fact
Wi-Fi Analyzer on a 1.69'' Screen
One of the manufacturer's Arduino examples, 04_GFX_ESPWiFiAnalyzer, draws the signal strength of nearby Wi-Fi networks on the board's screen. Other examples show, among others, a simple analog clock, the time from the PCF85063 chip and the QMI8658 motion sensor readout in LVGL. The examples work in Arduino IDE, and separate projects are prepared for ESP-IDF.

Frequently Asked Questions
Does the ESP32-S3-Touch-LCD-1.69 board come with a battery?
No. The set includes only the board; connect a 3.7 V lithium battery to the MX1.25 connector underneath.
What can I use to program the ESP32-S3-Touch-LCD-1.69 board?
In Arduino IDE or ESP-IDF. The manufacturer provides ready examples, including ones with LVGL.
How do I check the voltage of the battery connected to the board?
The program reads it through a divider on pin GPIO1. The manufacturer provides an LVGL measurement example.
Can you use the board's documentation in AI tools?
Yes. The manufacturer's documentation page lets you ask an AI a question and copy the content to an AI tool.
