DIY LED Thumb Flowing Light Soldering Kit – 81 LEDs Microcontroller
DIY LED Thumb Flowing Light Soldering Kit – 81 LEDs Microcontroller
DIY LED Thumb Flowing Light Soldering Practice Kit
Build your own dynamic LED display with this hands-on electronics soldering kit! Featuring 81 LEDs arranged in a thumb-shaped pattern, this kit produces eye-catching flowing light animations controlled by a dedicated DX158 microcontroller. It's an ideal project for electronics hobbyists, students, and anyone looking to sharpen their soldering and circuit-assembly skills.
⚠️ Please Note: This kit is designed for individuals with prior electronics and circuit experience. We cannot guarantee 100% success after assembly — please read all instructions carefully before purchasing. Due to manufacturing batch variations, some units may feature a Type-C power interface. If this matters to you, please confirm before ordering.
Key Features
- 81 LEDs arranged in a thumb-like pattern with dynamic, adjustable flowing light effects
- Press button S2 to cycle through and adjust the animation speed
- Pre-programmed DX158 microcontroller — the firmware is already burned and ready to go
- Powers via 4–5V DC; compatible with standard 5V USB charging heads
- Dual-compatible power socket: 1.3mm DC socket (default) or Android interface power socket
- S1 power switch included for convenient on/off control
- LEDs are modular — swap them out for different colors or multi-color effects anytime
- Great for learning row-column LED matrix scanning and microcontroller-driven circuits
Circuit Overview
The 81 LEDs are connected to the DX158 microcontroller in a row-column matrix configuration. The microcontroller scans and drives each LED in sequence, creating smooth flowing animations. The C1 filter capacitor is optional and not included in the kit — its absence does not affect performance.
Installation Tips
- All LEDs and microcontroller components are polarity-sensitive — double-check orientation before soldering
- Use a quality soldering iron and take your time for clean, reliable joints
- Replace LEDs with any color of your choice to personalize your display

Frequently Asked Questions
Q: Do I need to program the microcontroller myself for this LED soldering kit?
A: No programming required! The DX158 microcontroller in this kit comes with the firmware pre-burned, so you only need to solder the components correctly to get the flowing LED light effects working right away.
Q: What power supply does the DIY LED flowing light kit need?
A: The kit operates on 4–5V DC. Any standard 5V USB charging head is compatible. The default kit includes a 1.3mm small DC socket, though some batches may include a Type-C interface instead.
Q: Can I customize the LED colors on this soldering practice kit?
A: Yes! The kit accepts standard LEDs, so you can easily swap out the included diodes for any color — or mix multiple colors — to create a completely custom flowing light display.
Q: Is this kit suitable for beginners learning to solder?
A: This kit is best suited for those with some prior experience in electronics and circuit assembly. Beginners are welcome to try, but should be comfortable with soldering basics and understanding polarity-sensitive components before starting.
