What boards using the LDK220M-R are built for
LDK220M-R: common questions
Where can I find a LDK220M-R reference design?
Each of the 7 boards on this page is a real design using the LDK220M-R. 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 LDK220M-R use?
Most are built on RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the LDK220M-R?
The median is 29.7 × 19.2 mm, and 43% are two-layer designs.
What is the most popular open source board using the LDK220M-R?
By GitHub stars, Cellsim-8ch by atopile, with 29 stars.
Can I simulate one of these boards using the LDK220M-R 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.
