Benchy Motherboard - AM625
About the Benchy Motherboard - AM625 PCB
Benchy Motherboard - AM625 is an open source STM32 PCB design by Daxxn, published on GitHub under the AGPL-3.0 license. It is a 8-layer board measuring 300 × 120 mm, with 990 components from 176 distinct parts.
Its main chip is the 0807-0200-00008, from the STM32 family. Other key parts include the 0811-0402-00009, 0810-0000-00001, 0811-0401-00013, 0811-0401-00028 and 0805-0200-00003. By type, the board carries 433 capacitors, 376 resistors, 72 ICs, 43 connectors, 32 transistors and 10 diodes.
From the project
New and improved Benchy, now with more doodads!
Your electronics workbench buddy! (Warning - Benchy is not actually your buddy and will probably try to kill you. It's hideously expensive, and way too time consuming to build!)
- Single Board Computer running embedded linux - 5 Port USB 3.1 hub - All data ports are properly protected agains over-current and backfeeding - 2 USB 2.0 ports for the SBC peripherals (keyboard/mouse) - 2 1Gb Ethernet ports - 8 Software controlled relays for general things like lighting - (In Development) Lab Power Supply W/ Current or Voltage Limiting (15V @ 2A) - Lighting system that can drive 4 RGBW, 2 RGB, 6…

Benchy Motherboard - AM625: common questions
What microcontroller does the Benchy Motherboard - AM625 use?
The Benchy Motherboard - AM625 is built around the 0807-0200-00008, from the STM32 family.
How big is the Benchy Motherboard - AM625 PCB?
The Benchy Motherboard - AM625 measures 300 × 120 mm, has 8 copper layers and is 1.671733 mm thick.
How many components are on the Benchy Motherboard - AM625?
990 components, from 176 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Benchy Motherboard - AM625 design files?
From the Daxxn/BenchyReloaded repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Benchy Motherboard - AM625 design in my own project?
Yes, under the terms of its AGPL-3.0 license, which Daxxn chose for the repository.
Can I test firmware for the Benchy Motherboard - AM625 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
