IR2101: common questions
Where can I find a IR2101 reference design?
Each of the 9 boards on this page is a real design using the IR2101. 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 IR2101 use?
Most are built on AVR/Arduino (3), STM32 (2) and RISC-V (1).
How big is a typical board using the IR2101?
The median is 75.1 × 57 mm, and 50% are two-layer designs.
What is the most popular open source board using the IR2101?
By GitHub stars, XESC by embeddedalpha, with 75 stars.
Can I simulate one of these boards using the IR2101 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.
