This standard version does not include a battery and is intended for operation using external power via the USB-C port or with a user-supplied 3.7 V Li-Ion / Li-Po battery, which can be connected via the onboard MX1.25 battery connector. The integrated AXP2101 power management IC supports battery charging and power control once a battery is connected.

The board features a 1.75" round AMOLED capacitive touch display, offering very high contrast, wide viewing angles, and excellent readability. Additionally, it includes a dual-microphone array, audio codec, onboard speaker, and a 6-axis IMU, enabling multimedia, interactive, gesture-based, and voice-controlled applications.

The board supports both ESP-IDF and Arduino environments, enabling fast prototyping and simplified application development.
