Have you needed a learning electronic circuit kit? If your answer is yes, then you should not miss this product. It is called DSO138 oscilloscope diy kit, a very practical item and suitable for the novices and professional DIY enthusiasts. Then, let me introduce you something detailed about it.
It composed with ARM Cortex-M3 processor and a 2.4-inch color TFT display that can be used as ARM test development board. The PCB size is 117*76mm, while the screen size is 52*40mm. And the operating voltage is DC 9V. Besides, its sampling buffer depth is 1024 bytes and the analog bandwidth is 0 to 200KHz.
On my opinion, there are two useful function of DSO138 oscilloscope diy kit. One is the negative delay function that you can observe the precious trigger waveform. Second is the hold function, you can freeze at any time waveform display.
Although its circuit is simple and easy, as an available source, the professional people can do a secondary development on the basis of the kit. For example, it can be changed into data loggers.
In concluded, as a learning electronic circuit kit, DSO138 oscilloscope diy kit is easy and simple operating. However, it also needs some basic electronic ability, otherwise you may not DIY it successfully. If you are interested in it, then you could buy it and I’ m sure that you will not be regret.
