PIC18F87K22 microcontroller. Featuring nanoWatt XLP™ technology, it has
1
16 MIPS operation, 128K bytes of linear program memory, 3896 bytes of linear
data memory, and support for a wide range of power supply from 1.8V to 5V.
16MHz crystal oscillator. We carefully chose the most convenient crystal
2
value that provides clock frequency which can be used directly, or with the PLL
multipliers and dividers to create higher MCU clock value.
VCAP jumper. Some PIC18FK and all PIC18FJ microcontrollers have cores that
3
work on 1.8V-2.5V voltage range, and peripherals that work with 3.3V and
5V voltages. Internally, those microcontrollers have power regulators which
adjust the core voltage levels. In order for those devices to have a stable
operation of the core, manufacturer recommends that decoupling capacitive
lters should be provided, and connected between specic microcontroller
pins designated with VCAP and GND. This MCU card provides a VCAP jumper
which is used for this purpose. Jumper is removed by default.

USB communication lines. These two jumpers, when in USB position, connect
4
D+ and D- lines of the on-board USB connector with RF3 and RF4 microcontroller
pins. Since PIC18F87K22 doesn't support USB, jumpers are in I/O position.
4
VUSB line jumper. For PIC18F8xJ5x devices, this jumper should be connected
5
to VCC for enabling internal USB controller. Since PIC18F87K22 doesn't support
USB, this jumper is in I/O position.
ENVREG selection jumper. PIC18FJ and PIC18FK microcontrollers are using
6
internal voltage regulator which is enabled by placing this jumper in VCC
position.
