This tiny ESP32-S3 packs an impressive amount of hardware into 24mm. The M5Stack ATOMS3R is a tiny IoT controller built around a dual-core ESP32-S3 running at up to 240MHz, with 8MB Flash and 8MB PSRAM. It also has a 128×128 color display, BMI270 6-axis IMU, BMM150 magnetometer, programmable button... and IR transmitter, plus USB-C and expansion GPIO. At just 24 × 24 × 12.9mm and 6.8g, this is small enough to disappear inside the project you are building. You can program it with Arduino, ESP-IDF, PlatformIO or UiFlow2, so it is a pretty capable little platform for embedded and IoT experiments. At $17.50, it is the kind of board you can throw into a project just to see what you can build. Tiny board. Full ESP32-S3. Lots of possibilities.show more

It’s impressive how much functionality fits into just 24 mm. The tiny 128×128 color display makes the data clear and interactive without taking up valuable space—a great example of compact IoT design.

With an IMU, magnetometer and radio packed this tightly, I'd check magnetic bias under different loads and timestamp drift during Wi-Fi bursts. Small boards make integration easier; clean, time-aligned sensor data still takes deliberate engineering.

What if you could pick up an ESP32-S3 and play with it without touching the hardware? I made an interactive 3D ESP32-S3 simulator that runs directly in the browser. You can click GPIO pins to toggle them, lift the shield can, watch the board boot, switch camera angles and even export screenshots. Try it.

What if you could run ESP32 firmware without touching a physical board? Espressif's open-source ESP Emulator lets you run firmware binaries for chips including the ESP32-C3, C6, H2, P4, S3, and S31. You can even try it in your browser. Upload a merged firmware ".bin" file and watch the emulator run, with a live view of the console, CPU registers, memory and GPIO activity. For embedded developers, this opens up new ways to test firmware, debug execution and experiment before moving to hardware. Would you trust an emulator to test your next ESP32 project before flashing a real board?

What If Your ESP32 Could Listen to Satellites? I found TinyGS and this is such a cool way to get into satellite communications. TinyGS turns low-cost ESP32 and LoRa hardware into a ground station that can receive packets from LoRa satellites, weather probes and other compatible flying objects. You can build a station with boards like Heltec LoRa, TTGO LoRa32, T-Beam or even an ESP32 with an SX126x or SX127x module. ESP32-S3 boards are supported too. Once running, your station can automatically tune for satellite passes and send received data to the TinyGS network, where you can see stations, satellites and received packets from the community. It is a great way to learn ESP32, LoRa, RF, satellite tracking and ground-station technology with relatively inexpensive hardware. Would you build a tiny satellite ground station? Follow along for more ESP32, robotics and embedded projects.

ESP32-P4 booting up and running CircuitPython 🚀🐍 Core CircuitPython dev Scott has been chugging away at adding ESP32-P4 support to CircuitPython - and today tossed us a bin file that runs on the Eval board we got last week from Espressif. Native USB is still in progress, but we can connect to the REPL and save files using the USB-Serial converter. It's so fast at 400mhz, and with 16 or 32 MHz of PSRAM, it's going to be an awesome board for embedded Python! More soon! #espressif #esp32 #esp32p4 #python #adafruit #espfriends #circuitpython John Lee

Spent $20 on a tiny 1.5" ESP32-S3 TFT LCD board, plugged it in, and Claude basically knew the whole chip immediately. Now it's running a falling-sand sim with gusty wind, curated color palettes, and a different personality every boot — at 91 fps. 🏜️

What if you could program an ESP32 just by chatting with it? Espressif's ESP-Claw brings an AI agent framework to ESP32 devices. You can describe what you want your device to do, and the agent can use tools and dynamically loaded Lua code to turn that idea into hardware behaviour. It supports MCP, structured memory, event-driven actions, and messaging through platforms like Telegram. Imagine telling your device to monitor a sensor, switch on a fan when the temperature rises, or trigger an action when an event occurs. The interesting part is bringing AI agents closer to the actual hardware, on affordable embedded boards. What would you ask an ESP32 AI agent to build first?

Can you get a computer chip for $5? It's called an ESP32, and it's the same microcontroller found inside countless smart devices and loT products. For just a few dollars, you can buy one mounted to a development board, giving you easy access to power programming, and all of its input/output pins. Despite their tiny size, these boards can interface with sensors, motors, relays, displays, and countless other electronic components. Think of it as a tiny programmable brain that you can teach to monitor, control, or automate a specific task. They're incredibly popular for hobby projects, but they're also found in commercial products and industrial applications. If you've ever wanted to start building your own electronics, an ESP32 is one of the best places to begin.

Every time I think the ESP32-S3 has hit its limit, someone finds another gear. This open-source Jet renderer is now pushing the S3 even harder. Real-time screen-space reflections, water ripple distortion, lens flare and 8 ships on screen, all running on a tiny MCU. Performance dropped from around 60 FPS to 45–50 FPS, but that's still wild for an ESP32-S3. And the developer thinks there is more performance left to squeeze out. No GPU. No desktop CPU. Just an ESP32-S3 doing real-time 3D graphics.

Developers, this isn’t just a badge; it’s an ESP32-S3 waiting for your next project. 👀 It's basically a customizable, always-on color e-paper display that can move between your bag, desk, fridge, or workspace. ✔ 3.7-inch color e-paper display with 48+ native colors ✔ ESP32-S3 inside with open-source support for custom projects ✔ Clip ring, built-in magnet, and desk stand ✔ Upload and edit designs through the mobile app ✔ Share your portfolio, profile, or links instantly through NFC ✔ Over two months of battery life with daily use ✔ Clear, paper-like visibility—even in direct sunlight The biggest advantage isn’t just the display—it’s how many different roles one small device can take on. You can use it as a digital bag charm, anime badge, task board, event pass, portfolio card, fridge note, or even build your own integrations with the ESP32-S3. Because it’s e-paper, it uses no power to keep an image visible after refreshing. That makes it feel less like another distracting screen and more like a piece of calm, programmable technology. For developers, makers, artists, and anyone who enjoys customizing their setup, TICKEY is more than a digital accessory. Check it out on Kickstarter:

An ESP32-S3 with a 3.97-inch e-paper display. What would you build? This Waveshare board combines an ESP32-S3 with a 800 × 480 e-paper screen, making it useful for low-power projects that need to display information without constantly refreshing a backlit display. Think desk dashboards, e-book readers, weather stations, or smart labels that update over Wi-Fi. The e-paper display keeps the image visible even when power is removed, making it a great fit for mostly static information.

Building a robot dog? This ESP32 board was made for it. Petoi Biboard is an ESP32-based development board designed for multi-joint robots, with up to 12 PWM servo outputs built right in. It also includes an onboard IMU for balance and motion sensing, wireless connectivity, expansion interfaces and audio features. The BiBoard V1 adds features such as a voice command module, speaker and Raspberry Pi support. What makes it especially interesting is the software ecosystem. The board works with Petoi's open-source OpenCat framework, giving developers a solid starting point for building quadruped robots instead of creating everything from scratch. An ESP32, 12 servos and open-source robotics software. That's a pretty good starting point for building your own robot dog.
