The smallest esp32 module (so far…)

Some months ago, Espressif announced the production of a new chip, named ESP32-PICO-D4. It’s a complete SiP (System in Package), that is a chip which integrates the esp32 microcontroller, a 4Mbit flash memory, a crystal oscillator, filter capacitors and RF matching links. The chip datasheet is available on the official website. Using this chip, it’s possible to create very small modules. I…

ESP32, PlatformIO

PlatformIO is an opensource ecosystem (as it’s defined in the homepage of the project) to develop IoT projects. The heart of the platform is a software component named PlatformIO Core. This component includes: [checklist] a cross-platform compiler a libraries and dependences manager a serial monitor [/checklist] PlatformIO Core is developed in Python and therefore it can run on…
