JYETech 13805K DSO138 Mini Digital Oscilloscope 200KHz DC 3.5V-6V

DSO138mini brings in the following improvements: Better structure and smaller size. The bulky pin-headers connecting the LCD and main board in old DSO138 has been eliminated. The soldering of these pin-headers has being found problematic for beginners. USB or battery powered. This makes the scope much more convenient to be used as a portable device. New version analog board (PN: 109-13801-00H, aka "H version") can accommodate a battery charger JYE118 (see here) to make the device more practical. External trigger input. This input can accept a TTL or LVTTL signal as trigger source. Serial output of waveform data. This means captured data can be saved and displayed by PC. For example, this photo shows a captured single byte (0x35) sent from a serial port at 115200bps. This photo shows the same waveform displayed on PC using Gnuplot. General controller. The main board can be used as a general purpose control board with LCD display. MCU ports were brought to board edges for easy connection to the target system. There are a few optional parts that can be chosen to make the oscilloscope even more complete: BNC connector. The kit comes with a two-pin header for the simple hook probes (see the manual). This connector replaces the two-pin header and will allow you to connect to standard professional BNC probe. Standard BNC probe.
