About the Brewery-3dp motherboard PCB

Brewery-3dp motherboard is an open source STM32 PCB design by WilliamPrime, published on GitHub. It is a 4-layer board measuring 140 × 100 mm, with 334 components from 63 distinct parts.

Its main chip is the STM32F407Z_E-G_TX, from the STM32 family. Other key parts include the MCP6004, LM61430AFSQRJRRQ1, LM25145RGYR, DOZ45N03T and USBLC6-2SC6. By type, the board carries 131 resistors, 74 capacitors, 52 connectors, 36 diodes, 30 ICs and 5 inductors.

From the project

A 3d printer expansion board designed to help with monitoring and managing thermals in a 3d printer, this will be achieved with an STM32 as the MCU and then a bunch of JST-XH ports for thermistors and fans. It should be the perfect board if you feel like having FAR too many thermistors under the disguise of science!

- supports 12-30V input -20 buffered thermistor inputs - 12 fan outputs each with selection between 5V,12V and Vbus - 12V is dropped down with a buck converter on the board with 12A max - if the input voltage is 12V the 12V buck shouldnt be used - 5V is dropped down with a buck converter on the board with 12A max

- 4 Pwmed outputs meant for heaters or really beefy fans - 35A max per output, 62A max across all of the ports - the heaters are on a seperate fuse and terminal in, allowing you to save power budget for fans or just run things at a different voltage.
