So I hooked up the NFC reader with my RPi2, to communicate with it over UART. I decided to try this before trying SPI/I2C with the Arduino, because this will give me more direct control. However I was unable to get my RPi to boot up. At first I thought it was a power supply issue (RPi was only drawing 30)mA, regardless of what was plugged in. Then I noticed that my phone was drawing 1.3A so it could not be an issue with the power supply. I checked online and by the behavior of the LEDs (the green blinks for a while before going off, red is on all the way), it is possibly booting up. As I do no have my Wifi dongle or a spare LAN wire with me, I could not check using the network. Then it hit me, it must be the HDMI-VGA causing the issue. Now this converter works with my laptop, but I do not recall it working with the RPi before. Probably cannot draw enough power from it? However it still does not explain why the RPi is only drawing 300mA, even without anything plugged in. I guess I will have to monitor or check online if that is its standby power requirements (at 5V).
Anyways, here are some photos.
The package
The bill
The goods, all sealed up. Good thing is that the bad is reusable.
All the things it came with. at first I did not know what those two black things on the top left were for, but then I realized they were to switch between ON and OFF for two variables.
Hooked up to the RPi2. I did not have my soldering kit in hall so I had to improvise. It was a little hard as not everything was spaced evenly (between different sectors). I have bend the jumper wires to try and ensure contact but won't know until I fire up the RPi.
After trying everything and before packing everything into the box so that I can bring them home and try them on the HDMI monitor. Ignore my watch.
