I probably need to make another pass through and verify that I got all of the locations of things correct and then I will probably have a few of these boards fabricated for me. I2C EEPROM - Added the eeprom plus PU resistors. I have this default through shunts to use USART 3 XBee: Setup to do voltage conversions - Need to verify I did this correct. 1 group has PU resistors for PS2ġ6 Analog pins with 3 pin headers - Again can choose vs/+5V on each 4 pin group. The biggest challenge was to leave enough room free to allow for an XBee.ģ2 Digital IO pins with 3 pin headers- that you can choose VS/+5V on groups of 4 pins. The board is larger than standard Lynxmotion boards, but for the majority of my robots that should not be an issue.ĭipTrace-PCB-Arduino-Mega.jpg 1100×850 130 KBĪs you can probably see, I have this board pretty full of stuff. What I came up with was a board that had 3 out of 4 mounting holes that match up with the Standard Lynxmotion boards. I tried both Eagle and Diptrace and found that I personally prefer Diptrace. So I started to play around with some of the different CAD programs out there. Note: personally I am not that big into shields, and wish there were boards that had the basic functionality that I want, but when in Rome… Both of these platforms are based on the Arduino Mega footprint… I think it would be a lot of fun to try out several of my robots on these newer platforms, so I thought it would be nice to have a shield that had all of the things I needed and that I could plug into these boards. Also hopefully soon Arduino will release the Arduino Due, which is a 96mhz 32 bit ARM processor. The boards and IDE make them reasonably compatible with the Arduinos. I have also experimented with the Chipkit boards which are based on an 80mhz 32 bit Pic32MX processor. I like this board as it is compact and not that different in size to the normal Lynxmotion boards. This included the fun with experimenting with a shield for the Arduino Mega, that was built to plug into the Seeeduino Mega. Over the last many months, I have had the fun of experimenting with several different Micro-controllers and having a lot of fun.
