What it does

ESP32 GPIO pinout with ADC, DAC, touch sensors, strapping pins, and boot behavior. Accurate and practical reference.

Interactive ESP32 GPIO pinout reference tool with ADC, DAC, touch sensors, strapping pins, and boot behavior. Includes comprehensive guides for UART, SPI, I2C, PWM, and more.

GPIO pins 6-11 are internally connected to the flash memory. Digital I/O on these pins will trigger system exceptions. Comprehensive documentation for every ESP32 peripheral. From ADC and PWM to I2C, SPI, and UART. ADC1 vs ADC2, Wi-Fi conflicts, resolution, and Arduino code examples. 16 channels, frequency/resolution trade-offs, LED fading, servo control. T0–T9 touch sensors, touchRead(), wake-from-sleep, calibration. Wake sources, RTC GPIO, ULP co-processor, battery optimization. OV2640 camera, SD card, power, programming, troubleshooting. Head-to-head specs comparison. Which chip should you choose? Printable quick reference card. GPIO, ADC, strapping pins, variants. 1.8M+ pins mapped · 38…from esp32pinout.netlify.app

  • Interactive pinout for the Raspberry Pi Pico 22025 · pico2.pinout.xyz · ▲150

    I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched. Recently I've updated these with a new "Upside-down" view to complement the rear view, giving a pinout in the right orientation to match your project. The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and…

  • Open-Source 8-Ch BCI Board (ESP32 and ADS1299 and OpenBCI GUI)Jan 2026 · github.com · ▲54

    Hi HN, I recently shared this on r/BCI and wanted to see what the engineering community here thinks. A while back, I got frustrated with the state of accessible BCI hardware. Research gear was wildly unaffordable. So, I spent a ton of time designing a custom board, software and firmware to bridge that gap. I call it the Cerelog ESP-EEG. It is open-source (Firmware + Schematics), and I designed it specifically to fix the signal integrity issues found in most DIY hardware. I believe in sharing the work. You can find the Schematics, Firmware, and Software setup on the GitHub repo: GITHUB…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
