Training for electronic production , complete detailed descriptive information , like schematics , instructions, etc., making a high success rate . Component species diversity for students to identify elements , inline elements welding, soldering SMD components training. Students can get in at the same time making a practical tool for audio, video synchronization , low-frequency switching power supply , infrared receiver transmitter signal waveform and many other occasions, effectively observed and measured , increased interest in learning, improve learning outcomes . Kits using ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4 -inch color TFT display can be used as test ARM development board . Available source , the ability of a friend can be secondary development kit based on , for example, it can be changed to Millivoltmeter , data loggers , and so on .
