This ESP32-S3 1.91" development board has the ESP32-S3R8 chip and its vibrant and colourful 1.91" AMOLED display, with a resolution of 240 x 536, 16.7 million colours and a wide 160° viewing angle is perfect for running GUI programs like LVGL with ease. The board includes a QMI8658 6-axis IMU, an SD card slot, and a lithium battery header, giving you the option to expand. With compatibility for Pico headers, it offers easy integration and flexibility for expanding your projects. Available in both touch and non-touch versions (Please select the option you want before adding to the cart), the touch option supports 5-point touch and includes interrupt output, communicating with the touch chip via an I2C connection. Powered by an Xtensa 32-bit LX7 dual-core processor with a 240MHz main frequency, you can be sure that whatever project you are working on, this board has got your back! It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an onboard antenna and also allows for an external antenna connection by resoldering a resistor. This board comes with a built-in 512KB SRAM, 384KB ROM, 16MB Flash, and 8MB PSRAM. It includes a QMI8658 6-axis IMU, providing a 3-axis accelerometer and a 3-axis gyroscope for motion detection and step counting. For added convenience, it has a USB Type-C port for power, program downloads, and debugging, as well as a 3.7V MX1.25 lithium battery recharge/discharge header. There are 4 options to choose from: * No Touch without Headers * No Touch with Headers * Touch without Headers * Touch with Headers Please select which option you want before adding to your cart! Please note: this board uses a tiny MX1.25 connector for LiPo power. Most LiPo batteries on the market (including ours) use a larger JST fitting. We do not yet stock batteries with an MX1.25 connector, however, you can customise your battery with one of our 1.25mm pitch cables to make a compatible battery yourself (assuming you have the ability, knowledge and tools to do this safely).
