DSO138 Oscilloscope Manufacturing Kit
Features of the DSO138 Oscilloscope manufacturing kit:
1. Oriented towards electronic production training, the instruction materials are complete and detailed, including circuit diagrams, production guidance, usage instructions, troubleshooting methods, etc., with a high success rate of production.
2. There are various types of components, which are suitable for students to train in component identification, through-hole component soldering, and surface mount component soldering.
3. A practical tool can be obtained simultaneously during the production process, which can be used for audio and video synchronization, low-frequency switching power supply, infrared receiving and transmitting, etc.
4 Effective observation and measurement of signal waveforms in multiple situations can increase learning interest and improve learning outcomes.
5. The kit adopts an ARM Cortex-M3 processor (STM32F103C8) and includes a 2.4-inch color TFT display, which can be used as an ARM development test board.
6. The circuit is simple, reliable and inexpensive.
