ESP32-S3-Touch-LCD-1.69 is a high-performance microcontroller development board. In a small form factor, it has a 1.69-inch capacitive touch LCD screen, a lithium battery charging chip, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), RTC and other peripherals, making it easy to develop and embed applications into products. Equipped with a high-performance Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240 MHz. Supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE), with an onboard antenna. Built-in 512KB SRAM and 384KB ROM, stacked 8MB PSRAM and external 16MB Flash. Onboard 1.69-inch capacitive touch LCD screen, 240x280 resolution, 262K color, can clearly display color pictures. Built-in ST7789V2 driver chip and CST816T capacitive touch chip, using SPI and I2C interface communication respectively, without occupying too many interface pin resources. Onboard QMI8658 six-axis inertial measurement unit (3-axis acceleration, 1-axis gyroscope), can detect motion posture, step counting, etc. Onboard PCF85063 RTC chip, reserved 1.25 RTC battery slot (supports charging), can conveniently realize RTC function requirements. Onboard RST, BOOT and a side button with customizable functions, convenient to use buttons for custom function development. Onboard 3.7V MX1.25 lithium battery charging and discharging interface. Lead out 4 GPIO, I2C and UART pads, which can be used for external devices and debugging, and flexibly configure peripheral functions. Support flexible clock, module power separate setting and other precise control, to achieve multi-scenario low power consumption mode The touch screen has high transmittance, fast response and long life. Different batches may have different appearance, which does not affect use.
