From the project

The master PCB for minesweeper ROBOT 2023

This pcb used to control 4 DC motors and 4 SERVO motor. this pcb receive 3 ultrasonic sensor for wall detect and one DIY metal detector. this pcb receive commands from NRF or ps2 using SPI commnacation protocol. this pcb desplay the sensor dectect on LCD using I2C commnacation protocol. this pcb can handle 5 Ampere output current using current booster cicuit. this pcb have over current protection (FUSE)). this pcb use Arduino Mega for control and have a breakout for the arduino. the input voltage(24-12)V and the output voltage that you can take is 5v,12V.

Minesweeper: common questions

What microcontroller does the Minesweeper use?

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

How big is the Minesweeper PCB?

The Minesweeper measures 116.3 × 144.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Minesweeper?

48 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Minesweeper design files?

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

Can I use the Minesweeper design in my own project?

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

Can I test firmware for the Minesweeper 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.
