P2PNode SMD is an open-source printed circuit board by gr1d-init, from the gr1d-init/p2pMeshCommLearningKit repository on GitHub, published under the MIT licence. It is a 2-layer board of 97.5 × 58 mm with 24 parts on 53 nets, routed with 270 tracks and 0 vias.
It is built around the ATMEGA328P-AU, NRF24L01 and AMS1117-3.3. Its parts include 4 resistors, 4 ICs, 4 switches, 3 capacitors and 3 diodes. It belongs with the AVR (ATmega, ATtiny) boards of this library.
For this project, our main targeted users were particularly the high school students who are able to comprehend most basic peer-to-peer mesh communication knowledge which often included in STEM subject syllabus such as Computer Science and Physics subject.
Other than that, students are also exposed to an exciting involvement in Arduino kit development, lies under the usage of microcontrollers, which is a foundational skillset for their Reka Bentuk Teknologi subject that includes hardware and software implementations.
In short, we want student to head the ground up, build up a Peer-to-Peer Mesh Communication Device on their own with given instructions manual, enhance their practical skills on utilise a microcontroller and strengthen their understanding towards wireless communication protocols.

It measures 97.5 × 58 mm and has 2 copper layers, 1.6 mm thick.
24 parts, built around the ATMEGA328P-AU, NRF24L01 and AMS1117-3.3. 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 gr1d-init/p2pMeshCommLearningKit repository on GitHub, at the commit this page was made from: the board is kicadModels/P2PNode_SMD/P2PNode_SMD.kicad_pcb and its schematic kicadModels/P2PNode_SMD/P2PNode_SMD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
