Most likely, no LEDs will illuminate on the FONA. Otherwise, it will just stay solid white, which is just fine for now. If you have a PiTFT image on your Pi's SD card the screen should also boot up. If you slide the slide switch the LEDs on the Power Boost should illuminate and the Raspberry Pi should power up. THE PI IS ALREADY BEING POWERED BY THE LITHIUM ION BATTERY WHILE TESTING, MAKE SURE YOU DO NOT PLUG IN A 5V MICRO USB. Place the PiTFT over your Raspberry Pi A+.Solder a wire from the "KEY" pin on the FONA to Pin 40 (GPIO 21) on the Raspberry Pi.Solder a wire from the middle terminal of your slide switch to the "EN" pin (Enable) on the Power Boost.Connect the 5V line on the Power Boost to a 5v pin on your PiTFT.Also connect the GND pin on the power boost to a ground pin on the PiTFT (Same Pinout as the first 26 pins on a Raspberry Pi, notice the arrow and "1" indicating pin 1, which is 3v3).Solder a wire from GND on the power boost to one terminal on a slide switch.Solder a wire from GND on the FONA to GND on the Power Boost.Connect "bat" on the Adafruit FONA to "bat" on the Power Boost.Now that we have that out of the way, lets start making connections. Instead of connecting to the Raspberry Pi, connect your wires to the 26 pin male header on the PiTFT. In the Fritzing diagram, there is a Raspberry Pi. Now lets start wiring everything together.
