T-micro32 Open Smartwatch v/s TTGO T-Watch-2020

T-micro32 Open Smartwatch

The T-micro32 Open-Smartwatch is designed by Paul’s 3D Things, manufactured and developed by the Chinese electronics specialist LILYGO. It is based on the T-micro32 module and features a wide range of wireless connectivity through the support of Wi-Fi and Bluetooth. Additionally, the smartwatch comes with a fancy circular LCD display and power battery charge. Hence, it allows discharge management circuit, USB to TTL software upload circuit. With all these peculiarities, the manufacturer has open-sourced the hardware for you to customize it according to your needs.

We have already seen the TTGO T-Watch-2020, a previously updated version of LilyGO’s affordable ESP32-powered smartwatch that had been officially released, fixing some of the issues with the bulky original. The T-Watch-2020 was a brand-new enhancement in appearance based on T-original Watch’s developable programmability.

The original TTGO T-Watch was released a few years ago by LilyGO, a Chinese electronic manufacturer. It supported the expansion of its integrated hardware with add-on boards. This unfortunate creation of the core device is too voluminous for comfortable usage for the long term. The T-Watch2020, on the other hand, was much slimmer, and the company hopes to appeal to hackers and tinkerers.

Paul’s 3D Things is in charge of the hardware, software, and documentation. It has also made the KiCAD schematics and PCB design files. Additionally, it extends its support for the ESP-IDF C++ system, Arduino/PlatformIO, and MicroPython, available on the project website and/or Github.

Technical Features of T-micro32

A GPS Edition with a Quectel L96 GPS module, 4MB RAM, and a microSD card slot will also be available. People interested in creating their own smartwatch, STEM education, or designing a portable IoT gadget are among the use cases.

This latest release under LiLyGO, the T-micro32 watch, features a 1.3-inch circular LCD with a resolution of 240×240. It also comes with a 4MB flash with a ceramic antenna or u.FL antenna connector, whereas the TTGO-T-Watch-2020 has a 1.54-inch color capacitive touch screen display and an Espressif ESP32 system-on-chip 16MB QSPI flash memory with an operating frequency of 2.4GHz to 2.5GHz. The TTGO T-Watch-2020 is a smaller, less cumbersome version of the original T-GO watch.

TheT-micro32 offers a three-axis BMA400 accelerator along with Bluetooth connectivity of 4.2BR/EDR BLE and WiFi 4 2.4GHz 802.11b/g/n while the  T-Watch-2020’s SoC(System On a Chip) provides a similar three-axis accelerometer (BMA423), the key to its market target of people who are interested in building fitness and gesture tracking systems, to the T-Watch-2020 802.11b/g/n Wi-Fi and the Bluetooth 4.2 and Bluetooth Low Energy connectivity.

To meet all of the user’s requirements, the TTGO T-Watch-2020 can be programmed using common programming languages like Arduino, Scratch, MicroPython, Pictoblox, ESP-IDF(native SDK). In contrast, programming on the T-micro32 is compatible with Arduino, IDF, and MicroPython.
