I had to upgrade my Arduino IDE first then install the IDE. The easiest way seemed to be using the board manager URL. It took a couple of tries to&nbsp; find the working URL.<\/p>\n\n\n\n<p>Next step was to upgrade the boards firmware. That proved to be much harder than expected. The updater required OSX 10.9. I had to duplicate the above efforts on my newer Mac&#8230;.<\/p>\n\n\n\n<p>With all of that out of the way the blink sketch was uploaded and didn&#8217;t seem to be working. The problem turned out to be the SPI\/SD switch. When in SD mode it disconnects the led as well as the header pins&#8230;..<\/p>\n\n\n\n<p>Next step was to install an SD card and try a GPS logger example. That worked perfectly. Well it worked much better when I brought it upstairs. Being underground I was surprised it saw any satellites.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/mediatek\/Screen%20Shot%202015-10-16%20at%207.04.31%20AM.png\" alt=\"\" \/><\/figure>\n\n\n\n<p>Now looking deeper I was a little concerned that it only has 3 Analog inputs and 2 PWM outputs. That seems to rule out simple RGB control for Led&#8217;s without using a Maxim or Microchip I\/O extender chip.&nbsp; Looks like there will be some I2C or serial expansion chips needed for my next project with this board&#8230;.<\/p>\n\n\n\n<p>The idea of being able to plug in a Sim card and to be able to send &amp; receive SMS Texts or make calls without extra hardware is promising. I just have to see what US carriers will be compatible.<\/p>\n\n\n\n<p>Its a little hairy dealing with those flopping antennas so I decided to mount it to a plate before something breaks&#8230;.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/mediatek\/Screen%20Shot%202015-10-16%20at%207.13.23%20AM.png\" alt=\"\" \/><\/figure>\n\n\n\n<p>At first I was concerned about using the mounting holes that go through the shield but they have nylon spacers in there&#8230;<img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/mediatek\/Screen%20Shot%202015-10-16%20at%207.14.54%20AM.png\" alt=\"\" width=\"600\" height=\"581\"><\/p>\n\n\n\n<p>Next is to add a Wifi and an SD upload whenever its sees my server. I still have to look into GSM sim card options&#8230;..<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I was pleasantly surprised today when Fedex delivered a small package from Instructables.
