The ESP32-S3 is endowed with two noteworthy USB features that its predecessor, the original ESP32, lacked: USB OTG and USB CDC/JTAG. This blog post delves into the platformio.ini settings that govern the USB behavior of the ESP32-S3, with a particular focus on logging in CDC/JTAG mode.

In an earlier blog post we described how to use the ePulse dev board to send messages over ESPNow to achieve ultra long battery life. Now we wanted to test our new development board – the ePulse Feather – with a similar setup.

In this short video we are showing how easy it is to turn the Icon64 into a beautiful word clock.
Continue reading Icon64 – Word ClockWhen was the last time you were thinking about your breathing pattern or the algorithm that forms it (or does the pattern form the algorithm)? I guess it is safe to assume that if your answer is “never” or “it’s been ages” you will be like most readers. Also, if the term spirometry does not ring a bell with you: relax, welcome to the club. Spirometry is the measuring of breath by the way.
Continue reading Breathing LEDs – cracking the algorithm behind our breathing patternIn an earlier blog post, we presented tricks to increase the battery life of your typical ESP8266 or ESP32 application. In this blog post, we show you how to prolong your device’s battery life from 7 months to 44(!) months.
Continue reading ESP32 – Ultra-Long Battery Life With ESP-NOWUsing our Icon64 acoustic LED device we built a truly Swiss CO2-monitor by integrating a Sensirion SCD4x CO2 sensor – designed, engineered and built in Switzerland.
The SDC4x offers an unmatched price-to-performance ratio despite coming from a country with very high living and production costs. Furthermore, it more than breaks the size barrier in CO2 sensing. A CO2 sensor of such precision and accuracy in a <1cm3 package is unheard of.
We built the Icon64 with extensibility in mind from the very beginning. This allows us to react quickly to specific customer requirements. The Swiss C02-monitor is a result of this.
The Icon64 CO2-monitor is perfect for your classroom, living room, and (home-)office.
A student asked me yesterday: how did we manage to survive so far without?

With 27 students it takes about 15min until it blinks red. Opening the windows for five minutes brings the level down to 500ppm and everybody continues to work with peace of mind.

One ESP32 alone is already a powerful microcontroller. But what can you do when you have two modules built into one device? In this blog post, we discuss applications for the ThingPulse ESPGateway
Continue reading The ESPGateway – Part 2: ApplicationsDid you ever get to the point where one ESP module just wasn’t enough? In this article, we are going to present the ThingPulse ESPGateway and why we designed it this way.

The below chapters explain how we turned the existing cross-platform GUI-wrapper around the Espressif esptool.py into an app store.
In order to make our devices more accessible for customers who do not feel at home with PlatformIO or the Arduino IDE we developed the App Fairy. The App Fairy is a self-contained app store for your computer. It allows to install and configure applications for our devices without editing any source code. Best of all? The App Fairy does not require installation itself. Just click and go!
