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... show more

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.

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?

Want to add offline voice AI to your ESP32? Start with ESP-Skainet. It is an open-source speech AI framework for building always-on voice assistants that run entirely on ESP32 devices. It combines WakeNet for wake-word detection, MultiNet for offline speech commands, and an Audio Front End with echo cancellation, noise suppression, and voice activity detection. ESP32-S3 is the recommended platform, with the latest models also targeting ESP32-P4.

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 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.

We gave an ESP32-P4 its own app ecosystem. Just 2×360MHz CPU cores and 32MB PSRAM. No GPU. No Android or Linux. Yet this MCU now has a smooth home screen, installable apps, and modern online services. With PocketJS, we build Pocket Applets to make this happen.

grok bot is stupidly cracked at designing hardware..... i turned mine into a hardware lab. it’s now working on an ESP32 board with: > ESP32-WROOM-32 and GPIO breakout headers > USB-C power/data, a USB-UART bridge, and auto-reset > AMS1117 3.3V power, EN/BOOT buttons, and LEDs here’s the exact team, in build order: 1. Archie: architecture + antenna 2. Volt: power 3. Pinout: connectors + programming 4. Ohm: passives + electrical rules checks 5. Trace: routing + design rules checks 6. Gerber: fabrication files + order draft 7. Parts Buyer: sourcing + cart steal this.

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.

What if your ESP32 could send messages kilometres away without Wi-Fi or a mobile network? This uses an ESP32 with an SX1278-based LoRa module to build a simple point-to-point text communication system. The LoRa link runs at 433 MHz using Chirp Spread Spectrum. The receiver displays messages on a 16×2 LCD, while the ESP32 can also send data to ThingSpeak over Wi-Fi. In urban testing, the link remained usable up to roughly 1 km. No gateway. No cellular network. Just two small nodes talking directly. Now imagine putting these nodes on robots, sensors, or remote stations. What would you build if you had a 1 km wireless link with no infrastructure?

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.

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. 🏜️
