+
+The Open Authenticator is an open source TOTP based hardware authenticator using
+ESP32. In layman's terms, this does what Google Authenticator or Authy does.
+This uses a custom built pcb and a 3d case, also it uses a firmware built for
+this purpose using esp-idf, uses lvgl as the GUI library.
+
+The features of open authenticator's [printer circuit board](https://github.com/Open-Authenticator/hardware-design) are:   
+
+* Small form factor of 82mm x 42mm
+* Uses ESP32-WROOM-32D module
+* Uses 128x64 0.96" inch OLED panel
+* Uses DS3231 RTC with battery backup (CR2032) for timekeeping
+* Powered by 3.7V 300 mAh LiPo battery
+* Uses MCP73831 for charging LiPo battery
+* Uses TPS63001 Buck Boost Converter IC for efficient 3.3V power supply, with input range from 1.8V - 5.5V
+* Uses TPS22919 Load switch to control power to OLED and RTC chip
+* Autoselect power source, i.e., battery or USB
+* USB Type-C for charging only (no data pins connected)
