What boards using the TPS2121 are built for
TPS2121: common questions
Where can I find a TPS2121 reference design?
Each of the 9 boards on this page is a real design using the TPS2121. 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 TPS2121 use?
Most are built on ESP32 (7), RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the TPS2121?
The median is 60 × 70 mm, and 33% are two-layer designs.
What is the most popular open source board using the TPS2121?
By GitHub stars, MIDAS MK1 by ISSUIUC, with 31 stars.
Can I simulate one of these boards using the TPS2121 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.
