Overview
Stm32-module is an open-source printed circuit board by emb3rcia, from the emb3rcia/stm32-module repository on GitHub. It is a 4-layer board of 45.5 × 78.5 mm with 35 parts on 62 nets, routed with 691 tracks and 104 vias.
It is built around the STM32H7B0RBT6, RCLAMP0502BATCT and BL8072CLTR33, with the TPS73618QDCQRQ1 among its other parts. Its parts include 12 capacitors, 3 resistors and 3 connectors. It belongs with the STM32 boards of this library.

README
README.mdstm32-module
Hello! This is my first MCU devboard, made for HackClub's Blueprint program. It features 66 goldpins, USB-C (USB-FS standard) port for data AND power, integrated 3.3V and 1.8V LDO and ESD protection on VBUS, DATA channels and CC channels! It uses 4 layer pcb (Front and Back are for power, IN1 and IN2 for GPIO connection). It uses STM32H7 64-LQFP Package MCU on it! I made it so I can have some devboard on hand as one-for-all. This is why theres so much power in this thing (384MHz!!!) and this many GPIO ports, and also why this has 1.8V LDO. You use it like any other devboard, but note that it probably wont fit on breadboard, as it doesnt have the required distance present between connectors
Why i made it?
I thought it will be good learning project as well as giving me access to prototyping with mcu before commiting to making pcb. And i was right!
What i learned:
Mainly how to deal with tight connection layout on PCB near MCU

Q&A (no one said that but I want to include that lol)
Traces look ugly
It is my second completed project overall. Also they weren't like high speed eg pcie so I just connected them as well as I can! I will try to make them nicer before production, but no promises. EDIT: Tried to make them nicer when rerouting everything, it worked like you can see.
