This is a small (but huge on features) development board centred around the ESP32-S3 microcontroller. It has a dual-core Xtensa 32-bit LX7 processor operating at up to 240 MHz, with 512KB SRAM, 384KB ROM, 16MB Flash and 8MB PSRAM.
It has a colourful 1.8" AMOLED capacitive touch display with 16.7 million colours and a 368x448 pixels resolution, wrapped in a small case.
The board supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) via an onboard antenna. A USB-C port is available for power supply, programming, and debugging. It also features offline Speech recognition and AI Speech Interaction.
Additionally, there is a 6-axis IMU sensor (3-axis accelerometer and 3-axis gyroscope), an RTC, SD card slot, a low-power audio codec, a built-in microphone, and a speaker. The board also has a 3.7V MX1.25 lithium battery header for mobile power.!
Two variants are available - the board only, or the board with a 3.7V lithium battery. Please select an option before adding it 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). If you want to source your own battery to fit inside the case, a battery size of 3.85 x 24 x 28 mm is recommended.
Lithium Battery Shipping: Due to courier restrictions, the battery version of this product can only be shipped within England/Wales. With this item in your cart your shipping options will be limited and may cost more than our usual rates. Why?
