QX10 Titan QXPC Memory Board: common questions
What microcontroller does the QX10 Titan QXPC Memory Board use?
The QX10 Titan QXPC Memory Board is built around the ATMEGA32, from the AVR/Arduino family.
How big is the QX10 Titan QXPC Memory Board?
The QX10 Titan QXPC Memory Board measures 254 × 63.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the QX10 Titan QXPC Memory Board?
40 components, from 18 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 QX10 Titan QXPC Memory Board design files?
From the brijohn/qx10 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 QX10 Titan QXPC Memory Board design in my own project?
The repository has no license, so all rights stay with brijohn. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the QX10 Titan QXPC Memory Board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
