Welcome to your new project. Imagine what you can build here.

Microcontroller-based ozone generator control board for 12 V or 24 V DC input, drawing roughly 3.5 A at 12 V or 1.8 A at 24 V, with matched VIN-powered field devices, protected input, regulation, ATMEGA328PB control, pressure/flow sensing, MOSFET-switched load outputs, programming/debug headers, and status indicators.

Bilateral smart running insole data logger using two nearly identical ESP32-S3 pressure-sensing PCBs. Left variant is an ESP-NOW slave without microSD; right variant is the master with microSD logging. Both preserve the 16-zone FSR mux front end, LiPo charging, AP2112K regulation, USB-C charging input, JST battery connector, and the 280mm x 90mm 2-layer low-profile insole form factor.
