LilyGo sells Open-Smartwatch open-source hardware ESP32 watch by “Paul’s 3D Things”

We’ve beforehand lined three variants of LilyGo T-Watch-2020 smartwatch primarily based on ESP32 WiFi & Bluetooth SoC with TTGO T-Watch-2020 (V1) launched a few yr in the past, following by T-Watch-2020 V3 with a microphone for voice management, and T-Watch-2020 V2 with GPS.

The corporate has just lately launched a brand new rounded smartwatch primarily based on ESP32-PICO-D4 SiP with a twist as they didn’t design it themselves and as a substitute partnered with “Paul’s 3D Issues” for the Open-Smartwatch, and simply deal with manufacturing and manufacturing.

LilyGo Open-Smartwatch “Mild Version” specs:

• Wi-fi module – LILYGO T-micro32 module primarily based on ESP32-PICO-D4 module with dual-core ESP32 processor, 4MB FLASH, ceramic antenna or u.FL antenna connector
• Connectivity – Bluetooth 4.2 BR/EDR BLE and WiFi 4 2.4GHz 802.11 b/g/n
• Show –  1.3 inch round LCD with 240×240 decision
• USB – Micro USB for charging and programming
• Sensor – 3-axis BMA400 accelerator
• Debugging – USB to TTL by way of CH340E chip
• Misc -Reset button, 3x consumer buttons, DS323M RTC
  
• Energy Provide
  • 5V/1A energy enter by way of micro USB port
  • 2x solder pads for the battery
  • Battery charging and discharging safety chip (MCP73831)
  • Typical battery life ought to most likely be round at some point.

The {hardware}, software program, and documentation are absolutely dealt with by Paul, who launched the KiCAD schematics and PCB design recordsdata the Blender case design recordsdata, and help for ESP-IDF C++ framework, Arduino/PlatformIO, in addition to MicroPython on the project website and/or Github.

A GPS Version of the watch can also be within the works, with a Quectel L96 GPS module, 4MB RAM, and a microSD card slot. Use circumstances vary from folks occupied with making their very own smartwatch, STEM training, or design a wearable IoT system.
