Tetra Link boardIWQ: common questions
What microcontroller does the Tetra Link boardIWQ use?
The Tetra Link boardIWQ is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.
How big is the Tetra Link boardIWQ PCB?
The Tetra Link boardIWQ measures 85.2 × 55.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Tetra Link boardIWQ?
70 components, from 42 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 Tetra Link boardIWQ design files?
From the f1iwq2/Tetra_Link_boardIWQ repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Tetra Link boardIWQ design in my own project?
