2.4" Fully Assembled Digital Oscilloscope TFT LCD Display With Alligator Probe Test Clip for DSOO138 Oscilloscope Portable !!!Note: Acrylic Case needs to be assembled manually!!! [Acrylic Case] Material: Acrylic Product weight: 156 g / 5.52 oz Packing size: 16* 10 *4 cm / 6.3*3.94*1.57in [Oscilloscpoe] Feature: 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.
