LILYGO® TTGO T-WATCH 2020 V2 GPS IPS Open Source ESP32 WIFI Bluetooth Capacitive Touch Screen Programmable Watch Vibration Motor
| T-WATCH-2020 V2 |
| LILYGO T-WATCH-2020 V2 is used by replacing the MAX98357 speaker function of T-WATCH-2020 V1 with GPS and a 13pin expansion TF card holder and adding a DRV2605L tactile vibration sensor, which can be programmed to set different vibration status reminders. |
| T-WATCH-2020 V1 |
| LILYGO T-WATCH-2020 V1 is based on a design concept that can be programmed, can be worn, can be networked, and can be interactive. It integrates ESP32 with WIFI/Bluetooth, which is easy to program and develop and is more convenient to connect to the Internet. It uses the 2D IPS 1.54-inch watch capacitive touch screen of the OCA process, and the metal process frame of zinc alloy makes the device structure more sturdy and beautiful, suitable for wearable use. The sensitive capacitive touch screen makes human-computer interaction smoother. |
