FE1.1s: common questions
Where can I find a FE1.1s reference design?
Each of the 7 boards on this page is a real design using the FE1.1s. 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 FE1.1s use?
Most are built on ESP32 (2), ESP8266 (2), AVR/Arduino (1) and RP2040/RP2350 (1).
How big is a typical board using the FE1.1s?
The median is 95.2 × 69 mm, and 71% are two-layer designs.
What is the most popular open source board using the FE1.1s?
By GitHub stars, 6xUSB PowMet by aleksejm, with 7 stars.
Can I simulate one of these boards using the FE1.1s 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.
