Shopping for sensors, modules & components usually comes down to one question: do you want a guided set of modules for Arduino experiments, or a large supply of basic parts for building and replacing circuits? These kits serve different project styles, so the lower price is not the only deciding factor.
Quick verdict
Choose the Upgraded 37 in 1 Sensor Modules Kit for structured Arduino learning, named sensor and display projects, and a tutorial-led starting point. Choose the Electronic Components Kit 1390PCS when your priority is a broad assortment of LEDs, resistors, and capacitors in many listed values. The listed price gap is $48.85, making the choice especially clear if your project needs only basic components rather than sensor modules.
At a glance
| Decision point | Upgraded 37 in 1 Sensor Modules Kit | Electronic Components Kit 1390PCS |
|---|---|---|
| Listed price | USD 66.90 | USD 18.05 |
| Product emphasis | Sensor modules with a tutorial | LEDs, resistors, electrolytic capacitors, and ceramic capacitors |
| Project direction | Arduino UNO R3, MEGA R3, and NANO devices named | Multiple component values and types described |
| Learning support | Tutorial, CD, and listing paper | Component specifications and assortment details |
Where each kit wins
The Upgraded 37 in 1 Sensor Modules Kit wins for guided board-based exploration. Its module-focused scope is better aligned with a shopper who wants to work through sensor, display, and timing exercises instead of sorting through individual passive parts. The tutorial and named Arduino device compatibility give the purchase a clear learning direction.
The Electronic Components Kit 1390PCS wins for parts-led prototyping. Its assortment is organized around common circuit-building categories, with values spelled out for resistors and capacitors and colors identified for LEDs. That focus suits a workbench where choosing the right component matters more than following a project sequence.
Product notes
Upgraded 37 in 1 Sensor Modules Kit
The Upgraded 37 in 1 Sensor Modules Kit suits a shopper who wants a defined Arduino learning route, with a tutorial built for UNO R3, MEGA R3, and NANO. The description names project anchors including the GY-521 accelerometer, LCD1602 screen, and DS1307 real-time clock module; it also includes a CD and listing paper. That makes the package a direct match for guided sensor, display, and timing experiments. The concrete limitation is that boards are not included, and basic electronic knowledge is required. The description also mentions compatibility with the Arduino Official IDE and STM32, while the attributes identify Bluetooth and USB connectivity. Choose it for its module-led scope, not as a complete board-and-kit setup.
Electronic Components Kit 1390PCS
Electronic Components Kit 1390PCS fits projects that need basic parts in multiple values. Its description specifies 100 LEDs in red, green, blue, yellow, and white; 600 1/4W resistors across 30 values; 120 electrolytic capacitors across 12 values; and 30 ceramic capacitor types. That gives the assortment a concrete reason to choose it: breadth within LEDs, resistors, and capacitors. The limitation is equally specific: the stated contents are centered on discrete components, so the kit is a less direct fit for someone seeking named sensor, display, or real-time-clock modules. Select it when component variety matters more than an Arduino tutorial.
Final choice by use case
- For guided Arduino lessons: Choose the Upgraded 37 in 1 Sensor Modules Kit for its tutorial and stated UNO R3, MEGA R3, and NANO compatibility.
- For sensor, display, or clock experiments: Choose the Upgraded 37 in 1 Sensor Modules Kit, which specifically names the GY-521, LCD1602, and DS1307 modules.
- For LEDs, resistors, and capacitors in varied values: Choose the Electronic Components Kit 1390PCS.
- For the lower listed outlay: Choose the Electronic Components Kit 1390PCS, listed at USD 18.05 rather than USD 66.90.
The right pick depends on the work ahead: the 37-in-1 kit is the more targeted route for Arduino module learning, while the 1390PCS kit is the more direct match for a broad component assortment.
