GroupProjectCustom is an open-source printed circuit board by TeFka, from the TeFka/PeatMonitoringProject repository on GitHub. It is a 2-layer board of 72 × 64.6 mm with 73 parts on 84 nets, routed with 870 tracks and 130 vias.
It is built around the STM32L412RBT6P, TMP126EDBVRQ1 and 2N7002K. Its parts include 20 resistors, 16 capacitors, 5 transistors, 4 diodes and 3 ICs. It belongs with the STM32 boards of this library.
Designed by Oliver Davies
The main PCB for STM32 chip. Provides SPI, I2C, UART and analogue connections that allow communicaton with all relevant components. Connection to the battery is also availalbe to provide power.

It measures 72 × 64.6 mm and has 2 copper layers, 1.6 mm thick.
73 parts, built around the STM32L412RBT6P, TMP126EDBVRQ1 and 2N7002K. 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 TeFka/PeatMonitoringProject repository on GitHub, at the commit this page was made from: the board is Hardware/STM32_board/GroupProjectCustom.kicad_pcb and its schematic Hardware/PressureSensor/LPS28Report.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask TeFka before reusing the design.
