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…

Benchy2 Motherboard: common questions
What microcontroller does the Benchy2 Motherboard use?
The Benchy2 Motherboard is built around the STM32MP157FAB1, from the STM32 family.
How big is the Benchy2 Motherboard PCB?
The Benchy2 Motherboard measures 159.5 × 105 mm, has 8 copper layers and is 1.6196 mm thick.
How many components are on the Benchy2 Motherboard?
951 components, from 281 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 Benchy2 Motherboard 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 Benchy2 Motherboard 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 Benchy2 Motherboard 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.
