Firmware and Kicad project for my USB to UART/I2C/SPI converter

STM32 microcontroller with lots of periferials such as ADC, differential ADC, Input Capture, PWM, USB, Encoder, DAC, Digital Input, RTC, CAN-bus + Alarm etc.

A collection of Arduino boards recreated from scratch in KiCad. Legacy USB connectors have been replaced with USB-C where applicable.

A Custom STM32 board that runs on a battery with MCP73831 and is easily programmable with USB thanks to the CP2102 USB-to-UART chip.

This is a small module that handles the USB PD negotiation and simply outputs a specific DC voltage.

Custom software, firmware, and hardware for air quality monitoring

Framework Expansion Card that includes a USB hub to hide a bare dongle inside and still have a USB-A port externally

A simple USB to UART board designed with KiCad.

Dev board for RP2040 and FUSB302B

Open-source KiCAD 7 PCB project for a USB-enabled ATtiny85 Digispark-compatible board. Includes schematic, custom symbols, footprints, PCB layouts, and Gerber's for easy USB microcontroller prototyping and learning modern PCB design workflows.

Self-contained 5W Class-D amplifier inside a Speakon connector

A modular device designed to test electrical cables. It supports testing of both short cables (both ends accessible) and long cables (with ends far apart). The device visually indicates conductor continuity using LEDs.
