Overview

Product Description

This kit is part of the SMD Trainer range that only uses SMD parts to test out your soldering skills. Consisting of just two transistors, two capacitors, two LEDs, and four resistors, you will be able to create a dual LED flasher, and this kit is based on the MitchElectronics Transistor Flasher Kit, just a lot smaller. Before making this kit, be sure to read our SMD soldering guide found in our resources page, and pay extra attention when positioning components because de-soldering SMD parts can be extremely challenging.

Applications

  • The prime application for this kit is for soldering practice with SMD parts, and a successfully built board will result in the LEDs flashing one after the other. However, this board can also be used for other purposes, including as a flashing homing beacon for small drones and RC aircraft, a light ornament, and even as a clock source if the value of the capacitors are changed.
  • Education and training – Useful for teaching BJT transistor switching, astable multivibrators and RC timing, while providing practical experience with surface-mount soldering, component identification and post-assembly testing.
  • Project integration – Suitable for projects such as SMD Astable Trainer, Miniature Warning Beacon, Low-Frequency Clock Experiment, and other designs where the following function is useful: Surface-mount version of the two-transistor LED flasher, designed primarily as an SMD soldering trainer

Notes

  • Electrical specifications are nominal and may vary with component tolerances, supply voltage, load and operating conditions.
  • The product is supplied in kit form and requires soldering and assembly before use.
  • Check component values and observe the polarity or orientation of ICs, diodes, LEDs, transistors and electrolytic capacitors before applying power.
  • Battery or external power source is not included.
  • This trainer uses surface-mount components and is intended to develop SMD placement and soldering skills.
