Cirmall
Overview
________________________________________
Jakiro, named after the double-headed dragon in DOTA2, it supports 2.7-inch ink screen [264X176] and 0.96-inch color screen [160X80]. It can be replaced with a 2.4-inch touch screen at low cost, but only one screen is supported;
At present, the code is based on dual screens. The source code uses and refers to some open source libraries, thanks to relevant contributors;
Jakiro uses ESP32 as the main wireless mcu, relying on its rich resources and perfect ecological environment, it is very easy to get started, such as: Arduino, PlatformIO, Micropython;
Otherwise,
Jakiro integrates charging circuit, environmental sensor, motion detection, timing, microphone, speaker, TF card and other functions, So it is very convenient for application development;
Jakiro has also extended some interfaces, such as SPI, IIC, etc.;

What can I do with it?
________________________________________
• Personal calculator
• music player
• Weather forecast
• Business card replacement (7mm is too thick at present, but the optimization space is still very large, after all it is the first edition)
• Indoor environmental monitoring
• Internet radio
- Digital Photo Frames
• E-book
• Programming learning tools
• Speech Recognition
• Game console
• More interesting features are in the future

Jakiro, currently implementing basic functions such as weather, calculators, business cards, calendars, etc.;
After all, Jakiro is still in the prototype stage, so there is still a lot of improvement.
Jakiro is limited by the quality of 3D printing, the effect is not as good as rendering, continue to optimize.
