About the FireBot696 PCB

FireBot696 is an open source AVR/Arduino PCB design by evansfsu, published on GitHub. It is a board, with 27 components from 23 distinct parts.

Its main chip is the Arduino_Mega2560_R3_Shield, from the AVR/Arduino family. Other key parts include the A4988. By type, the board carries 17 connectors, 2 modules, 2 resistors, 1 transistor, 1 battery holder and 1 diode.

It belongs with the robotics & motion and sensors designs in this gallery.

From the project

Fire-fighting robot. Raspberry Pi 5 + Arduino Mega 2560, ROS2 Humble in Docker, YOLO on an ov5647 camera, skid-steer drive with two DFR0601 drivers, A4988 lead-screw clamp, solenoid pin-puller.

State machine: IDLE -> SEARCHING -> AWAITINGCONFIRM -> APPROACHING -> WARNING -> EXTINGUISHING -> COMPLETE -> IDLE`.

firebotmega.ino takes plain-English commands at 115200 baud when the Pi isn't plugged in. Type help in the Serial Monitor. Missing hardware is tolerated -- disabled sensors show off`, unwired outputs just toggle into the void.

FireBot696: common questions

What microcontroller does the FireBot696 use?

The FireBot696 is built around the Arduino_Mega2560_R3_Shield, from the AVR/Arduino family.

How many components are on the FireBot696?

27 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the FireBot696 design files?

From the evansfsu/FireBot696 repository on GitHub, which has the schematic and a netlist; the links under Design files point to each one.

Can I use the FireBot696 design in my own project?

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

Can I test firmware for the FireBot696 without the hardware?

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