ESP32 in Tinkercad and Online Tools
Tinkercad is where a lot of people learn Arduino — and then they go looking for an ESP32 inside it. Short version: it is not there, and it does not look like it will be. Here is the full story, the workarounds that mostly do not work, and what to use instead.
Does Tinkercad Have ESP32?
No. As of August 2026, Tinkercad Circuits’ component library stops at Arduino boards — Uno, Nano, Mega, a few others. No ESP32, no ESP8266, and nothing on Autodesk’s public roadmap mentions either chip.
Does Tinkercad Support ESP32?
Not officially, and “support” has two halves worth separating: a parts library and a compiler. Tinkercad compiles one fixed Arduino-style toolchain, and the ESP32 core is not in it — so even a perfect ESP32 part would never run ESP32 code. Both halves would need to exist for support to be real, and neither does.
Is There ESP32 in Tinkercad?
Officially, no. Community JSON part definitions circulate on forums, and a few people have gotten an ESP32-looking shape onto the canvas — but it is a drawing, not a chip. No Wi-Fi, no compiled ESP32 code, no peripherals. Depending on your account region, some community parts also load intermittently.
How to Add ESP32 in Tinkercad?
There is no supported path, and the workaround is not worth your afternoon. The custom-part trick — import a JSON part definition so a board-shaped object appears — sounds promising until you try it: I did this once, got the board rendered, and then watched it fail to compile a single ESP32 sketch. Tinkercad’s editor has no ESP32 core, so the board is decoration. If you need an ESP32 in a browser, skip the hack and use a dedicated ESP32 simulator that actually runs the firmware.
How to Get ESP32 in Tinkercad?
You cannot get the chip into Tinkercad, but you can get close enough for wiring practice: lay the circuit out with an Arduino Uno, note which pins map to which ESP32 GPIOs, and build the real code elsewhere. The pin mapping depends on your exact board, so keep the datasheet open while you translate.
How to Use ESP32 in Tinkercad?
You cannot use the ESP32 itself, but the workflow survives: Tinkercad for the circuit diagram and Arduino-basics practice, a real ESP32 environment for the code. One warning — Tinkercad’s parts sit in a 5V world and the ESP32’s GPIOs are 3.3V, so wiring that simulates cleanly in Tinkercad can drive a real ESP32 input outside its safe range. Do not copy breadboard photos from forums blindly.
What Can I Simulate Instead?
Browser simulators that compile and run real ESP32 firmware: Wi-Fi, BLE, sensors, UART logging — the same binary you would flash to a board. That is a different league from a schematic editor; the simulator MCP even lets AI agents write, run, and debug ESP32 code end to end, which is useful if you are experimenting with agent-assisted firmware.
Is Tinkercad Still Useful for ESP32 Projects?
Yes — for learning Arduino basics and practicing wiring layout, it is free and fast. Just do not expect the chip you will eventually flash to exist inside it; treat Tinkercad as the whiteboard, not the workbench.
Does Tinkercad Teach Arduino Code That Runs on ESP32?
The language is the same Arduino C++, so a blink sketch ported from Tinkercad runs on an ESP32 after changing the pin number. Anything library-heavy — sensors, displays, networking — will not, because Tinkercad ships its own small library set. It is a starter, not a reference; the Arduino IDE FAQ covers the real setup.
What’s the Fastest Way to Test ESP32 Code Online?
A browser simulator — no install, no account, no board. Paste a sketch, watch it run, debug it, then flash the same code to hardware later. Try it at app.sensbench.com.
Tinkercad Has No ESP32 — Our Simulator Does
Tinkercad Circuits is a fine sandbox, but its board list stops at the Arduino Uno and Mega. If your question is really “where can I try ESP32 code online”, the answer is here: our free browser simulator compiles real ESP32 sketches with arduino-cli and runs them on an emulated chip — no account, no install.
Start with these:
- Blink on ESP32 — the classic first sketch
- Wi-Fi scan — the example Tinkercad cannot offer at all
- Blink on ESP32-C3 and on ESP32-S3 — the newer chips, same workflow
