1- Introduction¶
The UNIHIKER is an innovative open-source hardware designed specifically for learning and using Python. It features a single-board computer architecture with an integrated LCD color screen, WiFi and Bluetooth, various commonly used sensors, and rich expansion interfaces. Additionally, it comes with a Linux operating system and Python environment pre-installed with commonly used Python libraries, which allows educators, students, or makers to step on a Python journey in just two simple steps.
2- Features¶
Supports running Python instead of MicroPython
Pre-installed Linux system, with ready-to-go Python and commonly-used libraries. Get started with Python in two steps
Multiple ways available for connecting, start coding at anytime anywhere
Highly-integrated hardware for teaching scenarios
Rich interfaces, excellent software compatibility & expandability
3- On-board Components¶
The UNIHIKER integrates commonly used components and provides rich external interfaces, which not only offer high convenience but also have unlimited expandability possibilities.
4- UNIHIKER System Framework¶
UNIHIKER adopts a PC and microcontroller dual-processor architecture. The CPU, memory, hard disk, screen, and peripherals constitute a computer system for running the Linux operating system. The microcontroller is responsible for controlling onboard components and external IO ports. The computer system controls the co-processor through the pinpong library.
