Mtdb hw: common questions
What microcontroller does the Mtdb hw use?
The Mtdb hw is built around the ATSAMD51J20A-AU, from the Microchip SAM family.
How big is the Mtdb hw PCB?
The Mtdb hw measures 90.2 × 101.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Mtdb hw?
296 components, from 64 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 Mtdb hw design files?
From the Sierra-Lobo/mtdb-hw 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 Mtdb hw design in my own project?
The repository has no license, so all rights stay with Sierra-Lobo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mtdb hw without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
