ESP32-C6 1.69" Touch Display Dev Board (240×280)

This is an ESP32-C6-based development board with a tiny 1.69" IPS capacitive touch display on the other side, packing a bunch of neat features like the built-in 6-axis IMU or the onboard microphone and included speaker!

Running the show is the ESP32-C6 with its dual-core architecture providing a high-performance (HP) 32-bit RISC-V processor with clock speed up to 160 MHz, and a low-power (LP) 32-bit RISC-V processor with clock speed up to 20MHz. The chip provides integrated Wi-Fi 6, Bluetooth 5 and IEEE 802.15.4 (Zigbee 3.0 and Thread) wireless communication. The chip provides  320KB ROM, 512KB HP SRAM, 16KB LP SRAM, and Waveshare have also added 16MB flash memory to the board alongside that.

The display is a 1.69" IPS capacitive touch panel, with a 240×280 resolution, 262K colours and 435 cd/㎡ brightness - controlled via SPI.

The board holds a bunch of other cool features too - an RTC chip, LiPo charging (MX1.25/Picoblade-compatible battery header), 6-axis IMU (3-axis accelerometer and 3-axis gyroscope), RESET+BOOT buttons, a programmable user button and solder pads for GPIO, I2C, USB, and UART pin access.

But wait, there's more! Included in the package is a 6Ω 1W speaker, which connects to the board via the MX1.25-Picoblade-compatible speaker header, and is supported by the onboard class-D mono amplifier, audio codec and onboard microphone.
