ReactPod: ESP32-C3 reaction buzzers – firmware, Config App (PWA), tools, hardware

The NDS331N is a MOSFET made by onsemi in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.3A 160mΩ@4.5V 162pF 20V 28pF 3.5nC@5V 500mW 700mV SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Transistors:N-MOSFET-D 1G 2S 3D, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 12,317 are in stock at JLCPCB (part C192741). 1 open-source board in 1 repository on GitHub use it.
