Adopt ARM -M3 processor , and include a 2.4-inch color TFT display screen. Used for secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers. easy to install and operate. With Auto/Normal/Single trigger modes, easy to capture the moment waveform. Available rising or falling edge trigger. Observable previous waveform before trigger(negative delay). With waveform parameter digital display, including frequency, period, duty ratio, MAX./MIN././-/virtual values. Short-circuit and open-circuit detection: can help the user find out the soldering error. TFT controller recognition function. The SMD has been soldered, more suitable for electronic beginner.
