A professionally structured, production-ready KiCad schematic integrating an ESP32-WROOM-32D with wired dual-port Ethernet, high-speed USB-C debugging, and an onboard AC/DC power supply.
A modification for Korg's Monotron Delay, which makes it accept standard Eurorack CV voltages (Pitch, Gate and Cutoff CV). The mod also provides an option to power the monotron via micro-USB.
This project involved the end-to-end design and development of a compact, low-power IoT system using the ESP32-C3-02 SoC and integrated TP4056 Li-ion battery charger. The goal was to create a reliable and modular platform for wireless environmental data monitoring, powered by a rechargeable battery with onboard protection and USB-C support.
My 4th attempt (though the first public one) at building a 4-cylinder USB-powered solenoid engine desk ornament.
