T-WATCH-2020 V3 Microphone IPS Touchable ESP32 WIFI Bluetooth Vibration Motor Speaker Three-axis Accelerometer Pedometer Programmable Watch Device

Introduction:

T-WATCH-2020 V3 is based on the hardware function of T-WATCH-2020 and adds the PDM microphone function, which makes the product functions richer and more interesting. With the MAX98357 I2S speaker, it is connected to the cloud and can be used to make intelligent voice control.

About T-WATCH-2020:

T-WATCH-2020 has three versions now, T-WATCH-2020 v1 version (Product ID: 1671427)

,

T-WATCH-2020 V2 version (Product ID: 1823064)

,

and T-WATCH-2020 V3 version (this item)

, where V3 is T-WATCH-2020 V1 based on the addition of PDM Microphone, T-WATCH-2020 V2 version replaces the function of MAX98357 of V1 version with GPS function and expands to TF card holder.

T-WATCH-2020 is based on a design concept that can be programmed, can be worn, can be networked, and can be interactive. Integrated ESP32 with WIFI/Bluetooth, easy to program and develop, and more convenient to connect to the Internet. 2D IPS 1.54 inch watch capacitive touch screen using OCA process, zinc alloy metal process frame, making the device structure more robust and beautiful. Suitable for wearable use, The sensitive capacitive touch screen makes human-computer interaction smoother.
