NNCpro
PlanAndBuild/NoNameComputer-2.0
The NoNameComputer 2.0 AKA NNCpro is being designed for mid-high power rockets and other flying vehicle. It will be equipped with various sensors like barometers, IMUs, magnetometer, current sensing etc.

The DO2300B is a MOSFET made by DOINGTER in a SOT-23 package with 3 pins. -50℃~+155℃ 1 N-channel 1.25W 1.5V 11nC@10V 20V 25mΩ@4.5V 5.2A 60pF 630pF N-Channel SOT-23 MOSFETs ROHS.
PCBKit's library has its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 20 are in stock at JLCPCB (part C41367404). 1 open-source board in 1 repository on GitHub use it.
The library has no symbol for this part yet.
