Philobot: common questions

What microcontroller does the Philobot use?

The Philobot is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Philobot PCB?

The Philobot measures 116 × 116 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Philobot?

56 components, from 36 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Philobot design files?

From the dish-glitch/Philobot repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Philobot design in my own project?

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

Can I test firmware for the Philobot 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.
