for fast and simple development of various
microcontroller applications. The board
is equipped with the PIC18F45K22
MCU that is placed in a DIP 40 socket and
contains male headers and connection
pads for all available microcontroller ports.
The pins are grouped according to their
functions, which is clearly indicated on the
silkscreen. The MCU comes preprogrammed
with mikroBootloader, but it can also be
programmed with mikroProg™ programmer.
The board also contains USB-UART module,
prototyping area and a power supply circuit.
It is specially designed to t into the special
white plastic casing so that you can turn
your PIC® project into a nal product.

1. Power supply
Ready for PIC® board can be powered in three dierent ways: via USB connector (CN1), via adapter connector using external adapters (CN2) or
via additional screw terminals (CN46). The USB connection can provide up to 500mA of current which is more than enough for the operation
of every on-board module and the microcontroller as well. If you decide to use external power supply, voltage values must be within 7-23V AC
or 9-32V DC range. Power LED ON (GREEN) indicates the presence of a power supply. Use only one of the suggested methods for powering
the board. If you use an MCU with a 5V power supply place jumper J1 in the 5V position. Otherwise, it should be placed in the 3.3V position.

mikroBootloader software
01 When you start mikroBootloader, a window as shown
in Figure 2-1 should appear.
Before starting mikroBootloader, connect Ready for PIC®to a
PC using the USB cable provided with the package

The board is equipped with mikroProg™connector pads,
which allow you to program the microcontroller using
external mikroProg™programmer. Before attaching the
programming connector, it is necessary to make a few
adjustments (Page 16).

First you need to cut the copper between pads for the external programmer, Figure 3-2. By doing so pins RB6, RB7, MCLR and VCC
on the MCU will be separated from the rest of the board. After that it is time to place (Figure 3-3) and solder (Figure 3-4) a 2x5
male header on the pad (CN5) . Now attach the external mikroProg™programmer connector on the 2x5 header, Figure 3-5. After the
programming process is nished you can remove the programmer connector and solder jumpers over pads in order to enable pins RB6,
RB7 to be used as I/O pins and MCLR to be used as a reset pin.

Fast on-board FTDI®chip allows Ready for PIC®to communicate
with a PC or other UART devices using a USB-UART connection. USB-B
connector (CN1) is used for connecting the USB cable. RX (receive)
and TX (transmit) LEDs will indicate communication status. Before
connecting the board to a PC, make sure that you have the
appropriate FTDI drivers installed on your operating system.
Drivers can be found at the following URL:

Proto area
allows you to expand
your Ready for PIC®board with
additional functionality. It can be done by
placing your additional components on the available
prototyping area. Pads are arranged in standard 100mils distance
form factor. There are 30 groups of 6 connected pads, two groups of 13
connected power pads (GND and VCC) and 186 unconnected pads.

6. Pin headers and connection pads
Each microcontroller pin is available for further connections through four on-board 2x5 connection headers and two 1x28 connection pads.
Pins are grouped in four PORT groups (2x5 male headers) as well as per their functions (1x28 connection pads), which makes development
and connections much easier. Everything is printed on the silkscreen, so that there will be no need of using microcontroller data sheet while
developing. Before using the pins, it is necessary to solder 2x5 male headers (1-4) on the board pads.
