Although not as innovative as this algae-powered computer, the LILYGO Watch-Keyboard-C3 V1.0 does turn the TTGO T-Watch ESP32 programmable smartwatch into a miniature desktop computer of sorts with a 1.54-inch touchscreen display. In other words, this accessory is not compatible with the Apple Watch or Samsung Galaxy Watch, just the TTGO T-Watch smartwatch series powered by the Espressif ESP32-D0WDQ6 chip with a dual-core 240MHz Tensilica Xtensa LX6 microcontroller.
Aside from the 1.54-inch touchscreen, this smartwatch comes equipped with single-band Wi-Fi, Bluetooth 4.0 connectivity, 520kB of static RAM (SRAM), 8MB of pseudo-static RAM (PSRAM), and 16MB of flash memory. The functional keyboard that you see can be paired over Bluetooth, while Wi-Fi 4 provides connectivity for all of you wireless networking needs and USB-C port for power / data. For those who don’t already have a TTGO T-Watch, both the keyboard and smartwatch can be picked up for $54.58 USD now from Aliexpress.
