+====== Using GPIO RA3 on a PIC16F1455 ======
+The PIC16F1455 is only a small microcontroller with 14 pins.
+{{ :pic16f1455:pic16f1455-layout.png?direct&300 |}}
+But there are limitations. As you start to allocate out and plan what functions the pins will perform in your design, the choices start to thin out quickly. Some GPIO pins share with other functionality.
+Eventually you need to double up on a pin to try and get the value from both features.
+For this article, I'll be picking on RA3.

+====== Repairing an Adafruit Grand Central M4 ======
+{{:grand-central:grandcentral.jpg?direct&300 |}}A while back, my friend, Professor McSwivells purchased an Adafruit Grand Central M4. Unfortunately it was dead on arrival, and after being in touch with the staff at Adafruit, they reluctantly refunded the purchase. The dead board went into a drawer and was forgotten.
+The professor recently found it again and thought he'd send it down to me on the off chance that it could be repaired or at least parts salvaged and recycled.
