ESP32-C5-Touch-LCD-1.69 is a low-cost, high-performance microcontroller development board designed by Waveshare. Adopting a compact form factor design, the board integrates a 1.69inch capacitive touch LCD, a Lithium Batt charging chip, an audio codec chip, a 6-axis IMU (3-axis accelerometer and 3-axis gyroscope), an RTC chip, and other peripherals, making it easy to develop with and integrate into products.

Key features include:

• Equipped with a high-performance 32-bit RISC-V processor with a clock speed up to 240 MHz, and a low-power 32-bit RISC-V processor with a clock speed up to 48MHz
• Integrated Wi-Fi 6, Bluetooth 5 and IEEE 802.15.4 (Zigbee 3.0 and Thread) wireless communication, with superior RF performance
• Built-in 8MB PSRAM and 16MB Flash memory
• Type-C connector for easier use
• 1.69inch capacitive touch LCD display for clear color picture display, with 240 x 280 resolution and 262K color
• Built-in ST7789V2 display driver and CST816T capacitive touch chip, using SPI and I2C communication respectively, effectively saving the IO resources
• Onboard QMI8658 6-axis IMU (3-axis accelerometer and 3-axis gyroscope)
• Onboard PCF85063 RTC chip for RTC function requirement
• Onboard RST button, BOOT button, and a PWR button for power on/off
• Onboard 3.7V MX1.25 Lithium Batt recharge/discharge header
• Onboard ES8311 audio codec chip, microphone, and speaker header for AI interaction
• Reserved GPIO, I2C, USB, and UART pads for external device connection and debugging, enabling flexible peripheral configuration
• Supports flexible clock, module power supply independent setting, and other precise controls to realize low power consumption in different scenarios
• High touch screen transmittance, fast response and long lifetime
