The following tutorial will guide you through the steps to install BennVenn's AGS-101 Voltage Regulator inside your AGB-001 + AGS-101 LCD mod. If you are planning on using a ribbon with variable brightness switch, there will be couple extra steps to achieve your goal. If you are planning on using a Digital Brightness Controller please refer to this tutorial once your VR is in place.

BennVenn's AGS-101 Voltage Regulators offer the best possible brightness for any AGS-101 mod, they are available from our shop here.

We assume you have basic soldering skills, that you know how to clean surfaces before soldering and that you already know how to do an AGB-101 mod. This guide will only instruct you on how to integrate the voltage regulator in your mod.

The wires we use are 30 AWG Silicone-Cover Stranded-Core.

NOTE: that the information given here is provided to the best of our knowledge at the moment of writing and could change over time. Anything you might do is at your own risk and we can't be held responsible if things turns out bad on your end. Attempt at your own risk.

Installation for Simple Ribbons

1. Required material


1. LCD Preparation

At the back of the AGS-101 LCD, there are 2 ribbons soldered to each other, the topmost powers the backlight. The following steps will explain how to isolate it without permanently damaging yout AGS-101 LCD.

  1. Carefully unsolder the top ribbon from the one below.
  2. Remove any excess solder from each of the 4 exposed pads, they need to be as flat as possible.
  3. While still in it's original position, apply a piece of tape over the bottom ribbon, covering it completely and firmly holding it in place.
  4. Position the top ribbon back in place, over the bottom ribbon and apply a piece of tape over the top ribbon so that the whole area is covered and held in place properly.
  5. Carefully carve a hole on the topmost tape to reveal the solder pads from the top ribbon.
  6. Your end-result should look like this:


2. Voltage Regulator Assembly

  1. Solder the short red wire to the In pad.
  2. Solder one of the short black wires to the Gnd pad.
  3. Solder the long red wire to the Out pad.
  4. Solder the blue wire to the Sleep pad.


    3. Voltage Regulator Installation

    You are now ready to install the regulator on the board. In wire goes to CP1's anode. GND to the battery's negative pad. Sleep goes to the top of C35.

    4. LCD Connection

    When we build our units, we proceed with the LCD connection once the shell's top assembly is complete.

    1. Solder the other end of the Out wire to the positive pad of the LCD (left).
    2. Use the remaining Black wire to connect the LCD's negative (right) pad to the battery's negative terminal (GND).

    5. Test

    Make sure there is no short and try powering it up! 

    6. Finalization

    To prevent damages and loose soldering due to movement, secure the voltage regulator inside a shrink tube. Then use electrical tape (rolled in O shape to expose glue all around it) to hold the regulator in place between the 3 electrolytic capacitors.

    You might need to cut some material from the shell's back to avoid squeezing the voltage regulator's wires.

    Close up the console and ...


    7. Enjoy!

    Installation for Ribbons with Switch

    The information is provided as is until we have more time to work on this tutorial. This depicts the VR v1 but the same logic applies to v2.

      Works like a charm. Had the ribbon with the switch and only difficult part was getting the resistor on the switch. It is so tiny!

      Also this guide is really helpful! Thanks for that.
