Full Scratch Drone: common questions

What microcontroller does the Full Scratch Drone use?

The Full Scratch Drone is built around the ESP32-MINI-1-N4, from the ESP32 family.

How big is the Full Scratch Drone PCB?

The Full Scratch Drone measures 40 × 36 mm, has 4 copper layers and is 1 mm thick.

How many components are on the Full Scratch Drone?

55 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Full Scratch Drone design files?

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

Can I use the Full Scratch Drone design in my own project?

Yes, under the terms of its MIT license, which Haruki-Ayukawa chose for the repository.

Can I test firmware for the Full Scratch Drone 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.
