Panoramic photo robot with Bluetooth control, based on Arduino MEGA 2560

Since everything in this schematic is either public or super simple I leave it as public too.
NOT for commercial use!
This project of mine has just been started so there is no firmware nor software (PC, Android) available yet. Currently I don't plan to make it public like the Arduino shield design.
If you like the shield, you can write your own code to control a camera and motorized panoramic head.
There are 3 motor drivers so a linear slide can be controlled at the same time with a panoramic head. The components related to any of the 3 driver modules can be left unsoldered and the shield would work just fine without that driver.
Warning!
The Micro SD module I plan to use has its own level shifter. Make sure you use the same or you risk damaging your SD card. There are also versions with resistor dividers which work only with slow communication speeds.

Used modules are as follows:
1) HC-05 Bluetooth V2.0 to serial adapter
HC-05 Bluetooth V2.0

2) Micro SD card module with level shifter

3) A4988 stepper driver module

Change Log

Rev2 - 03.2016

  • Fixed stepper motor driver component drawing and footprint (one side numbered in reverse originally)
  • Fixed optocoupler pin numbering (Emitter and Collector were switched)
  • Fixed camera connector drill diameter (connector couldn't fit in)
  • Fixed row spacing on 2X18 pin header connector (was more than 2.54mm)
  • All connectors have now reduced drill diameters (they fit too loose)
  • Fixed layout because of the fixes above

Rev1 - 02.2016

  • Initial version (obviously with errors)

First PCBs from EasyEDA arrived today. Quality is more than great for hobby projects and good enough for low complexity professional ones.

Unfortunately there are a few errors in my design. Connector P8 has smaller holes than it should and the motor drivers' footprints are mirrored.

Late night designs shouldn't be sent for manufacturing before mid-day sanity checks. Lesson learned. Money wasted.

If someone wants to use this PCB wait for me to fix it. I am changing the status to "Under development" or however it is called.

Footprints fixed now. PCB layout to be fixed soon.

We have featured this project, can you remove PANOKO1_shield_Rev1, it seems it is old.

Penoff

I am currently working on the Rev2 but I keep Rev1 just in case something goes wrong. I've had some issues with the editors (both schematic and PCB) and don't want to loose any data. I will probably remove it tonight after work when I have more time to play with it.

Hi,
May I know what are the issues, this is very important.
EasyEDA has version control, After every save, we will save a new copy for you. you can find the PCB's history via https://easyeda.com/account/history/ZtFROoYyw

I've seen the history and I actually used it. This Rev1 layout as you see it now is complete with only the copper pours removed. At least it was complete before I tried to update it when I updated the schematic, a couple of footprints and one component. After the update components were all gone as well as top side of the PCB layout. I can't tell exactly how it happened but it's a fact. I wish I could be of more help on this issue.

Another annoying issue for me is when I am editing some text over a component in the schematic editor. When I drag with the mouse to select some of the text while editing it, the component below it moves.

Penoff

Fixed and ordered for production again. I hope this time there are no mistakes. Might not be perfect but it should be functional now.
