DIY Kit DSO138 2.4" TFT Digital Oscilloscope Kit Precise Parts 1Msps

DSO138 oscilloscope production suite features:
Training for electronic production, complete detailed descriptive information, including schematics, production guidance, instructions, troubleshooting methods, 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.
Circuit is simple, reliable, inexpensive.
