Repair: Why every do-it-yourselfer should equip themselves with this digital microscope


Everything is getting smaller and smaller, including the components inside the gadgets we try to diagnose and fix. For years I’ve made do with a headband magnifier, but that’s not enough when it comes to components that are barely larger than the size of a grain of sand.

I needed a digital microscope. I needed the digital microscope Andonstar AD407 Pro.

Technical characteristics

  • 4 megapixel HD sensor
  • 7 inch IPS screen
  • Maximum video resolution of 2880 x 2160 at 24fps
  • Photo resolution 4032 x 3024 (12 megapixels)
  • Micro SD card storage
  • HDMI output
  • UV filter to protect the lens from damage
  • Two dimmable LED lights

Alright, enough tech specs, let’s see how the Andonstar AD407 Pro magnifies things? Let’s start with a circuit board.

On this small circuit board are tiny components. Some are barely visible to the naked eye.

Let’s take a closer look at them using the AD407 Pro. Here is a tiny capacitor held by my ceramic tweezers (by the way, I highly recommend ceramic tweezers for precision work).

The large 7-inch display makes it easy to repair parts as small as this capacitor. Just be sure to be careful when handling loose parts.

A remote control attached to the side of the microscope turns on the LED lights for better viewing.

The bottom of the display also features a row of convenient buttons for controlling magnification intensity and turning the microscope on and off.

Thanks to the power of the microscope, I was able to remove the tiny capacitor. To give you a better idea of ​​the size of this component, here it is on my fingertip!

It’s really tiny!

At €260, the purchase of the Andonstar AD407 Pro is justified if you are a professional or an electronics and computer enthusiast looking for a practical digital microscope. If you are an amateur or a beginner preferring a more affordable solution, I suggest the Andonstar AD206 which, for 130 €, is an excellent alternative. Its screen resolution and sensors are lower than the AD407 Pro, but the AD206 is still a great tool that will save you from squinting at the smallest objects!
