This is DSO138 2.4″ TFT Handheld Pocket-size Digital Oscilloscope Kit. This DSO138 digital oscilloscope kit adopts ARM Cortex-M3 processor and with 2.4-inch TFT screen. It’s easy and reliable for circuit operation. It can display frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values. This boost converter is a great match for the DSO138 oscilloscope kit. It can be connected directly to the DSO138 motherboard(not included), making the DSO138 oscilloscope a portable oscilloscope for better use.
