Slowtronics ESP32 & PlatformIO Crash Course: a $29 path from Arduino IDE to working ESP32 projects
If you keep bouncing between random Arduino tutorials, half-wired breadboards, and an IDE that feels like it’s fighting you, the missing piece is usually a clean path from blank project to working hardware. It helps to have a course that starts with the environment, then moves quickly into builds that make the ESP32 feel useful instead of mysterious. Slowtronics ESP32 & PlatformIO Crash Course is aimed at that exact jump: VS Code and PlatformIO first, then real projects like sensors, displays, Telegram bots, and Bluetooth. At $29, it is the kind of price that makes sense if you want a structured build path instead of another folder of scattered code. Slowtronics ESP32 & PlatformIO Crash Course is worth a look if you are ready to move from “I want to make an ESP32 thing” to a project you can flash, wire, and show.
Quick answer
| Best for | Beginners or Arduino IDE hobbyists who want a short, project-based path into ESP32, VS Code, and PlatformIO. |
| Skip if | You only want free video snippets, need a fully custom hardware design, or do not want to work with C++ and wiring. |
| Price | $29 |
| Format | Short video classes, organized source code, wiring schematics, and PlatformIO project files. |
| One-line take | A compact ESP32 course that trades long theory for builds: setup, web features, OLED games, Telegram bots, and Bluetooth. |

What you’re actually buying
At $29, the course is not trying to be a university degree. It is a compressed build path: you start with the environment, then move into projects that make the ESP32 feel useful instead of mysterious. The first class gets you into VS Code and PlatformIO, which matters because that is where many hobbyists get stuck before writing meaningful code. Instead of treating the Arduino IDE as the only option, you learn a workflow you can keep using for cleaner projects, debugging, and repeated builds.
The middle of the course is where the value lands. You work through the PlatformIO setup class, then move into WiFi web features, OLED display and games, IoT and Telegram bots, and the Bluetooth Grenade project. That progression is useful because it covers the parts of ESP32 projects that people actually want: local web control, visible output, sensor data, messaging, and wireless behavior. The included source folder gives you pre-configured PlatformIO projects, C++ code, and wiring schematics, which cuts down the “where do I even start” friction.
The hardware angle is also practical. The examples are tested across multiple popular boards, including the standard ESP32 Wroom DevKit, the compact S3 Super Mini, and the IdeaSpark 1.4-inch TFT display board. That does not mean every board will behave identically, but it does mean the course is not locked to one obscure setup. If you already have an ESP32 on the desk, this is a reasonable way to turn it into a working project stack instead of another unflashed chip.
Why it’s on our radar
The course shows a small but clean signal: 5 ratings, a 5.0 average, and about 70 visible sales. That is not a huge audience, but for a focused ESP32 course it suggests enough people have bought it to leave feedback. If you value compact, project-led learning over long theoretical courses, the social proof is light but positive.
What actually matters
Before paying, run these checks against your own bench:
- Board fit: The course covers ESP32 Wroom DevKit, S3 Super Mini, and IdeaSpark 1.4-inch TFT board. If you have a different module, check the board compatibility notes before assuming a one-to-one match.
- Comfort with C++ and wiring: This is beginner-friendly, but it is not a no-code kit. You will be flashing code, following schematics, and debugging with the Serial Monitor.
- Project match: If you want a Telegram bot, OLED game, web interface, or Bluetooth build, the class list is aligned. If you need a specific industrial protocol, custom PCB, or advanced RF design, this may not go far enough.
- Source folder access: The real time-saver is the organized source code, PlatformIO projects, and wiring schematics. Make sure that is what you want, not just a set of videos.
Mid-check
Before checkout, compare the current class list and price on View on Gumroad. That is the fastest way to confirm the five classes, source folder access, and board examples are still what you want.
FAQ
Is this for complete beginners?
Yes, if you are willing to do basic wiring and follow code. The course starts with setup and uses short video modules, so it is designed for people who have never touched a microcontroller before.
Do I need the exact boards mentioned?
No. The examples are tested across popular ESP32 boards, including the Wroom DevKit, S3 Super Mini, and IdeaSpark 1.4-inch TFT board. Still, confirm your board’s pins and display driver if you are using a different module.
What do I get besides videos?
You get an organized source folder with pre-configured PlatformIO projects, C++ code, and wiring schematics. That matters because it turns the course into a build path rather than just a watch-list.
Is this a replacement for Arduino IDE?
It teaches a VS Code and PlatformIO workflow, which is useful for cleaner project structure and debugging. You can still use Arduino tools, but the course is aimed at moving you into a more professional environment.
Bottom line
If your bottleneck is not interest but structure, this is a reasonable $29 entry point into ESP32 and PlatformIO. It gives you a short video path, real project files, and builds that go beyond blinking an LED.
