What boards using the 9V_LR are built for
9V_LR: common questions
Where can I find a 9V_LR reference design?
Each of the 2 boards on this page is a real design using the 9V_LR. 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 9V_LR use?
Most are built on STM32 (2).
How big is a typical board using the 9V_LR?
The median is 67.3 × 28 mm, and 0% are two-layer designs.
What is the most popular open source board using the 9V_LR?
By GitHub stars, SMDU PCB by sabanekko3, with 13 stars.
Can I simulate one of these boards using the 9V_LR 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.
