FLP PCB set: common questions

What microcontroller does the FLP PCB set use?

The FLP PCB set is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the FLP PCB set?

The FLP PCB set measures 70 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FLP PCB set?

118 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the FLP PCB set design files?

From the DSM-Interrupt/FLP repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the FLP PCB set design in my own project?

The repository has no license, so all rights stay with DSM-Interrupt. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the FLP PCB set without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
