What boards using the COS1333TR are built for
COS1333TR: common questions
Where can I find a COS1333TR reference design?
Each of the 2 boards on this page is a real design using the COS1333TR. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the COS1333TR use?
Most are built on AVR/Arduino (1) and RP2040/RP2350 (1).
How big is a typical board using the COS1333TR?
The median is 126 × 82.8 mm, and 0% are two-layer designs.
What is the most popular open source board using the COS1333TR?
By GitHub stars, SH-RPi hardware by hatlabs, with 56 stars.
Can I simulate one of these boards using the COS1333TR before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
