Overview
Esp32-p1-node board is an open-source printed circuit board by pe1mew, from the pe1mew/esp32-p1-node repository on GitHub. It is a 2-layer board of 108 × 57.5 mm with 20 parts on 13 nets, routed with 119 tracks and 162 vias.
It is built around the BAT54S, BC847 and BSS138. Its parts include 5 resistors, 3 capacitors, 2 transistors, 1 IC and 1 diode. It belongs with the radio and wireless boards and the ESP32 and RISC-V boards of this library.

README
README.mdTTN-Apeldoorn P1-Node
This is the P1-Node of TTN-Apeldoorn. The P1-Node is a LoRaWAN device that will read the information from intelligent energy meters (slimme meters) that have a P1-interface.
The node is designed for a LILYGO TTGO LORA32 868 Mhz ESP32 LoRa OLED node.
About the project
The TTN-Apeldoorn community is an active community since 2017. By organising meetups and projects for the community members a large group of IoT enthousiasts are regulary informed about a wide range of IoT topics and developments. With projects like Apeldoorn in data, TTN-Apeldoorn is involved in Citizen science projects of the township Apeldoorn. For one of the projects of Apeldoorn the P1-Node is developed and deliverde in a serie of 10 sensors.
The P1-Node is designed with reproduction by less experienced community members in mind. Although trough-hole-components are more easily to be solders by these community members the P1-Node is designed using SMD components. The chosen SMD components are the biggest possible (1206) that can be hand soldered. Also it is possible to introduce reflow techniques to the community members that they actually can do them selves.
It is planned to deliver a project to TTN-Apeldoorn community in which the members can build their own P1-Node.

Questions
How big is the Esp32-p1-node board PCB?
It measures 108 × 57.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-p1-node board use?
20 parts, built around the BAT54S, BC847 and BSS138. 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.
Where can I download the Esp32-p1-node board KiCad files?
From the pe1mew/esp32-p1-node repository on GitHub, at the commit this page was made from: the board is hardware/esp32-p1-node-board/esp32-p1-node-board/esp32-p1-node-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-p1-node board design in my own project?
Its repository states no licence, so its author keeps all rights: ask pe1mew before reusing the design.
