Dismantle your DSO nano

Dismantel your DSO nano is pretty easy, but it’s still worth writing a tutorial to let people know what does DSO nano look inside before open it.

Note:
This tutorial is for information purposes,  Dismantle the DSO nano and follow this tutorial at your own risk!

You will need:

A sharp knife (Or something else sharply)
A 1.4mm screwdriver

First you need to remove the top panel by using a sharp knife. The top panel is attached with the body by glue, be sure to do this slowly, or you will damage the acrylic panel .

Here you can see 6 screws(marked with white circle) after the top panel is removed. Remove them with a 1.4mm screwdriver, then go to the next step.

Remove the rest 2 screws, now you should be able to take the sub-board apart from the motherboard.

Sub-Board detailed pictures. 6 metal dome buttons were soldered on the top side, and 1×3.5MM TSR connector, 1X Mini usb connector on bottom.  There’s also a board to board connector to attach the 2 separated PCB.

Here we go, now you can take the screen and motherboard away from the case.

1. controller: STM32

2. stabilized voltage supply : 3.3V voltage output

3. stabilized voltage supply : 3.0V voltage output

4. stabilized voltage supply : use a P3232 RS-232 transceivers to output +5V and -5V voltage

5. general purpose dual J-FET operation amplifier : to separate and scale the input signal

6. 8-Channel Analog Multiplexer : change the match channel for different V/div

  1. Can it be reprogrammed to be something else? Can we get the schemaitcs and source-code or sample code?

  2. Hmm, such a big jump from 1.1 to 1.3a why not 1.1b or 1.2

    Oh well, if its a revision for the good. then its good. Im glad it is revised

    *is that a white jumper wire in the picture?

  3. The pcb showed DSO201v1.3A, the schematic posted on the forums is DSO201v1.1

    What are the differences? any updates?
