The Circuit Builder (Develop → Circuit Builder) is where you design and simulate the hardware circuit for your product — lay out components and connections and validate the wiring before you build physical hardware.

​
What it’s for

  • Plan the circuit your product’s firmware will run on
  • Simulate connections to catch issues early
  • Document the hardware design alongside the rest of the product
Pair it with the Firmware SDK (the code) and a hardware module (the physical board) to go from design to a working device.
