ESP32-S3 1.75" AMOLED Round Touch Display Dev Board (466x466)
This is a 1.75" display development board based on the ESP32-S3, with a range of neat features, and three different hardware variants options!
The board is controlled by an ESP32-S3R8 Xtensa 32-bit LX7 dual-core processor with up to 240MHz main frequency, supported by 512KB of SRAM and 384KB ROM, with onboard 8MB PSRAM and an external 16MB Flash memory. It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with an onboard antenna.
The display is a 1.75" AMOLED touchscreen panel with a 466x466 resolution, offering 16.7m colours. Compared to traditional LCDs, AMOLED offers better light control, with sharper detail and more vivid colours.
The rear of the board also features a dual microphone array for audio algorithms such as noise reduction and echo cancellation, suitable for accurate speech recognition and near-field / far-field voice wake-up applications. An 8Ω 2W speaker is also included for the dedicated speaker header. There's also a 6-axis IMU (3-axis accelerometer and 3-axis gyroscope), onboard RTC and a slot for a microSD card.
The board is powered and programmed via USB-C. Power can also be provided via the MX1.25/PicoBlade-compatible lithium battery recharge/discharge header (we sell compatible batteries in the store). IO is available via the onboard 8-pin header, providing 3x GPIO (16/17/18), UART (RX/TX) and power pins (VBUS/GND/3.3V).
