Choosing among sensors, modules & components often comes down to a practical fork: do you want an UNO R3-oriented breadboard setup, or a parts-first assortment of LEDs, resistors, and capacitors? The right pick depends on whether your next project begins with a board or with selecting individual components. Here is the useful split: the first kit emphasizes organized portability and UNO R3 applicability; the second makes a detailed mix of discrete parts its central focus.
Quick verdict
Choose Electronics Component Basic Kit with 830 tie-points Breadboard Resist for UNO R3 when your project starts with an UNO R3 board and you want a contained breadboard setup. Its price is USD 14.49.
Choose Electronic Components Kit 1390PCS LED Diodes Resistors Electrolytic Capacitors g when the priority is sorting through specified LED, resistor, and capacitor groups. It is priced at USD 18.05, a $3.56 spread above the first kit. Do not treat 830 tie-points and 1390PCS as a direct ranking: they describe different measures, so the project format should decide.

Where each product wins
Electronics Component Basic Kit with 830 tie-points Breadboard Resist for UNO R3

- Board-led projects: UNO R3 applicability is the most direct reason to choose this kit when the board is already central to the project.
- Storage and carrying: The white case, printed function sheet on the lid, and lightweight format give the kit a clear organization advantage.
- Compact setup: Its 180 × 85 × 45 mm package dimensions and 290g package weight suit shoppers who want a portable kit rather than a loose collection of parts.
Electronic Components Kit 1390PCS LED Diodes, Resistors & Electrolytic Capacitors

- Parts selection: It specifies 600 1/4W resistors across 30 values and 120 electrolytic capacitors across 12 values, making the assortment easier to match to component-selection exercises.
- LED work: The 100 LEDs are divided across five colors, a concrete advantage for projects that use different signal colors.
- Capacitor variety: The kit also identifies 30 kinds of ceramic capacitors, giving its component-first format a more detailed capacitor range.
Product notes
Electronics Component Basic Kit with 830 tie-points Breadboard Resist for UNO R3
The Electronics Component Basic Kit with 830 tie-points Breadboard Resist for UNO R3 is the clearer pick when the project starts with an UNO R3 board. The breadboard-centered format, printed function sheet on the lid, and multicolor signal lamps make the case feel organized for hands-on setup. Its 180 × 85 × 45 mm package dimensions and 290g weight also support a compact carry-and-store format. The limitation is focus: this kit is framed around UNO R3 use and breadboard organization rather than a detailed component-by-component assortment. Choose it for board-led tinkering and a contained kit format; if your priority is comparing many resistor, LED, and capacitor groupings, the Electronic Components Kit 1390PCS is the more direct match.
Electronic Components Kit 1390PCS LED Diodes, Resistors & Electrolytic Capacitors
Electronic Components Kit 1390PCS LED Diodes, Resistors & Electrolytic Capacitors puts individual parts at the center. It specifies 100 LEDs across five colors, 600 1/4W resistors across 30 values, 120 electrolytic capacitors across 12 values, and 30 kinds of ceramic capacitors. That breakdown is a concrete reason to choose it for component-selection exercises, LED circuits, or capacitor experiments. Its limitation is orientation: the emphasis is a discrete-parts inventory, not a setup explicitly tied to UNO R3 and a breadboard. Choose it when the component families matter more than a board-specific starting point; otherwise, the first kit's format is easier to match to that use.
Final choice by use case
- UNO R3 and breadboard projects: choose the Electronics Component Basic Kit with 830 tie-points Breadboard Resist for UNO R3 for its board-specific focus, organized case, and compact format.
- Parts-led electronics work: choose the Electronic Components Kit 1390PCS LED Diodes Resistors Electrolytic Capacitors g for its explicitly separated LED, resistor, and capacitor assortment.
The clean tie-breaker is your starting point: board first favors the UNO R3 kit; parts selection first favors the 1390PCS kit. The $3.56 spread matters, but it should follow the project rather than replace it.
