Neumi/open_echo
Open Source echo sounder / depth sounder / SONAR for bathymetry and research. Arduino based and compatible.

Breakout board for Arduino Nano development kit. On pins 3, 5 and 6 there are tracks for connection suitable for small SMD NPN transistor (such as MMBT2222A) for driving LEDs or some other light load.
ArduinoPLAY is an open-source printed circuit board by Nikolichnik, from the Nikolichnik/ArduinoPLAY repository on GitHub. It is a 2-layer board with 46 parts on 39 nets, routed with 131 tracks and 0 vias.
It is built around the MMBT2222A. Its parts include 33 connectors, 6 resistors, 3 diodes and 3 transistors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

46 parts, built around the MMBT2222A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Nikolichnik/ArduinoPLAY repository on GitHub, at the commit this page was made from: the board is Arduino_play.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Nikolichnik before reusing the design.
