Curiosity High Pin Count 28/40 (HPC) Development
Board Quick Start Guide
Overview
The Curiosity HPC Development Board layout and schematic can be found on the
Microchip website:
www.microchip.com/curiosityhpc
This board provides flexibility for experimentation through an application header with
ground (GND) and supply voltage (V
DD
) connections. It also includes a set of indication
LEDs, push button switches, and a variable potentiometer.
Additionally, it features two mikroBUS™ headers to accommodate a variety of plug-in
Click™ Boards that can be used in application development. All connections to the
mikroBUS headers, LEDs, switches and potentiometer are labeled with the
microcontroller port name for ease of programming. Curiosity HPC is fully compatible
with MPLAB
®
Code Configurator and MPLAB
®
X v3.05 or later.
Board Power-Up
Power is supplied by the Micro-USB connector on the left of the board.
Demonstration Program
After applying power to the Curiosity HPC Development Board via the USB connector
on the left side of the board, LEDs will automatically turn on. Turn POT1 clockwise to
increase the brightness of the LED D5 and counterclockwise to decrease its brightness.
Press the push button
S1
to turn on LED D4, and push button
S2
to turn on LED D3.
Board Layout
The Curiosity HPC Development Board is shown in
. A PIC16F18875 40-pin
microcontroller is populated in the center of the demo board next to the target device
label. The Curiosity HPC Development Board accommodates 40- and 28-pin 8-bit
microcontrollers. The PIC16F18875 is initially connected to the following components:
• Push Button (S1)
• Push Button (S2)
• Potentiometer
• Reset Button
• LEDs (D2 – D5)
• mikroBUS™ Header 1
• mikroBUS™ Header 2
The board is flexible and allows individual experiments. Power and ground (GND)
connections are available, as well as isolation by unsoldering of the solder jumpers. The
full pin breakout of the microcontroller is provided to expand the flexibility of the
Curiosity HPC Development Board.
