Unleashing Potential: Fusing TS100 With USB-C PD Trigger Board

Six years ago, when portable soldering iron was a bit of a novelty, there were limited to none to choose from. There might be available selections but were relatively unknown. Fortunately, the TS100 from Miniware emerged as a standout choice. It gained positive reviews from hobbyists and DIYers for its mini form factor and convenience suitable for traveling. Powered by a 12V to 20V DC supply, it was the perfect go-to tool for those on the move.

When I looked to purchase one, Miniware had just released the TS80, boasting a USB-C support. The problem was, that the TS100 was already an expensive soldering iron and the TS80 came at an even fancier price point. In the end, I picked the TS100 as an investment for someone like me starting out.

Fast forward to 2020, when we were all stuck at home and with spare time to tinker. That's when I found a finger-sized USB-C PD trigger module while browsing for electronic components in an online market. It is tiny enough to fit snugly inside my TS100's board and I figured it was a good time to streamline my workspace, fix all the dangling wires, and cut down the unnecessary power supplies. So when I received the PD trigger board that I ordered, I started disassembling my TS100, delicately removing the DC input, and seamlessly integrating the module onto the main board. It wasn't just about streamlining and reducing the clutter in my workspace but also enhancing the functionality of my soldering iron wherever I go.

1. TS100
2. USB-C PD trigger module (20V)
3. Rotary tool or utility knife
4. Extra soldering iron and desoldering pump

This step is straight forward. Unscrew the 3 screw to remove the cover revealing the circuit board. The circuit board is then secured by 2 screw. Remove them also. Once the circuit board is free, the next step is to remove the DC input.

This part is crucial part of the process. You have to carefully remove the DC input not to damage the entire board. You can desolder the DC input using your favorite desoldering tool. A spare soldering iron and a desoldering pump will do. As for my case, I don't have an extra soldering iron at my disposal hence I slowly and patiently grind the solder joint using a rotary tool. I set the speed to minimum and adjusted accordingly to not damage the nearby components.

In this step you have to have steady hands or use one of the handy third hand tool. I traced out the original DC input connection and connected the positive and negative of the USB-C PD trigger module as shown in the picture. I set the enough wire length and twisted it so I can properly mount the module upside down. As for the wire, I took it from the power supply and didn't care the gauge. I recommend to use a wire gauge that support 20V 65W rating.

Secure the board back to the panel using the two screw. Then proceed to the next step.

The USB-C PD trigger module is a little wider than the panel cover. Either you trim the trigger board or panel cover. I decided to trim panel cover since I have to bore a hole anyway as the original DC input opening is too little for the new USB-C input. Using a rotary tool, I drill and grind the side panel until I get the module fit and bore a larger hole to accommodate for the new USB-C connection. Unfortunately for me, I got too excited and crack the panel. It can be easily fixed with a super glue but as gentle reminder take it slowly and have a patience so this won't happen to you!

After all the cutting, carefully assemble the pieces back and secure with the screw.

I advice to have this done before the assembling or be like me - cross one's finger and hope everything will work as expected. Lucky for me, everything works like a charm. Now, my TS-100 is USB-C ready and all I need to do is plug it to any USB-C power charger.
