The ThymeWatchRound low-power AI smartwatch is based on the Espressif ESP32-S3 main control unit with PSRAM, featuring a rotating crown, a Sharp 64-color reflective display with backlight, excellent screen performance, metallic luster, and full-screen edge single-point capacitive touch. It supports magnetic USB charging and firmware downloads, and has a TF card slot, allowing the firmware to operate in USB Mass Storage mode when connected to a computer. It also includes music playback functionality. The S3 does not support Bluetooth Audio, so it uses a 2.5mm headphone jack, which requires an audio adapter due to the thin design of the watch body.
