README
README.mdcamRover
camRover is an ESP32-S3 rover platform with an OV7670 camera, two encoder-equipped DC motors, and addressable RGB LEDs. This repository contains the KiCad hardware design, release manufacturing files, and Arduino firmware used to bring up and test the board.
Repository contents
board_bringup/— Arduino ESP32-S3 firmware for camera streaming over Wi-Fi and testing motors, quadrature encoders, and LEDs.camRover_pcb/camRover_pcb_v1_1/— KiCad v1.1 project, hierarchical schematics, PCB layout, assembly files, stencil outputs, and release Gerbers/drill files.camrover_img.jpg— photo of the built rover.
Board bring-up firmware
The sketch captures OV7670 RGB565 frames at QVGA (320 × 240), converts them to JPEG, and serves a browser-based test page. The page shows the live video and provides motor pulses, encoder tests, and RGB LED controls. Motor commands have a 2-second firmware watchdog.
Build with Arduino IDE
Build tested with Arduino-ESP32 3.3.12.
-
Open
board_bringup/board_bringup.inoin Arduino IDE. Keepsccb_ov7670_compat.cppin the same sketch folder. -
Install/select the Arduino-ESP32 3.3.12 board package.
-
Select ESP32S3 Dev Module and set:
Setting Value Flash Size 16MB (128Mb)PSRAM OPI PSRAMUSB CDC On Boot Enabled -
Connect the ESP32-S3 board over USB, select its port, then compile and upload.
-
Open Serial Monitor at 115200 baud. After Wi-Fi connects, open the printed IP address in a browser.
Before uploading, set WIFI_SSID and WIFI_PASSWORD near the top of board_bringup.ino to your 2.4 GHz Wi-Fi credentials. The defaults in the sketch are local development settings; replace them for your network. The rover and browser must be on the same network. If Wi-Fi does not connect, motor and LED serial commands remain available.
Camera orientation and left-edge crop can be adjusted with CAMERA_ROTATION (0, 90, 180, or 270) and CAMERA_CROP_LEFT in the sketch.
Bring-up controls
The web page provides:
- Live OV7670 video.
- Forward/reverse pulse tests for each motor and both motors together; each web pulse lasts 750 ms.
- Encoder count reset and forward/reverse tests. Lift wheels clear before running encoder tests.
- Red, green, blue, white, and off LED controls.
Serial commands at 115200 baud:
| Command | Action |
|---|---|
m <left> <right> | Drive motors with values from -255 to 255 (1-second timeout). |
s | Stop motors. |
l <r> <g> <b> | Set all five LEDs; each color value is 0–255. |
e | Print encoder counts. |

PCB files
Open camRover_pcb/camRover_pcb_v1_1/camRover_pcb_v1_1.kicad_pro in KiCad. The project includes the main schematic and hierarchical sheets for the ESP32, motor drive, and power circuitry, plus the PCB layout and assembly bill of materials.
The CamRover_v1_1_Gerbers/ folder and CamRover_v1_1_Gerbers.zip contain the release copper, solder mask, paste, silkscreen, board outline, drill files, and drill maps for fabrication. Check the fabrication house’s layer and drill requirements before ordering.
