Abstract: This paper introduces FRIStack, a modular and open-source platform based on the ESP32 microcontroller family, aimed at education, rapid prototyping, and embedded systems development.

The RP2350 has a few advantages over its predecessor, one of which is the ability to load firmware remotely via UART, as [Thomas Pfister] has documented on his blog and in the video below. [Thomas] ...

For those of us lucky enough to have been at Hackaday Europe in Berlin, there was a feast of hacks at our disposal. Among them was [Vladimir Divic]’s gradients game, software for an M5Stack module ...

M5Stack’s Unit Gateway H2 is a small Thread/Zigbee gateway powered by the ESP32-H2-MINI-1 module with an 802.15.4 radio for Zigbee 3.0, Thread 1.3, and Matter connectivity. The Unit Gateway H2, also ...

The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

The m5stack_core2 board features a 5v bus domain, that for example is used by the grove connector. This 5V bus is not being supplied accordingly. In addition there currently is no possibility to ...

The M5Stack Cardputer is a tiny computer with a keyboard, display, wireless functionality, and a built-in microphone and speaker… all of which makes it sound more impressive and functional than it ...

The Universal Asynchronous Receive and Transmit (UART) interface is found on a variety of peripheral devices. Consider, for instance, a microcontrollerbased system with four such peripherals. Ideally, ...
