The Ready for PIC DIP28 Board is a great solution for fast and simple development of various microcontroller applications. It comes with a PIC18F25K22 that is placed in a DIP28 socket. The PIC is connected to an 8 MHz crystal oscillator, and is pre-programmed with a UART bootloader, so you don't have to use external programmers to program the microcontroller. The board contains four IDC10 headers for all available microcontroller ports. It also contains a USB-UART module, prototyping area and a power supply circuit. An optional white plastic case is available so you can turn your PIC project into a final product.
Pads are available on the board for installing a 10-pin programming connector in case you want to overwrite the bootloader, use a different microcontroller, or perform in-circuit debugging of your code. The connector would be compatible with the mikroProg for PIC.
The board measures 141 × 84 mm (5.55 × 3.3").

Three power options You can apply power to the board using the provided USB cable, which provides more than enough current for the MCU and every on-board module. If you want to use an external power supply, there is both a barrel connector and screw terminals to which you can supply 7-32V AC or 9-32V DC. Use only one method at a time.
External crystal The board contains an 8 MHz external crystal which delivers the the clock necessary for the operation of the MCU and enables fast UART bootloader baud rates.
Programming with bootloader For programming the microcontroller, you can use a bootloader program which is pre-installed in the MCU memory. To transfer a .hex file from a PC to the MCU, you can use the free mikroBootloader application. The board has a USB connector and ships with a cable to connect to your PC.
Programming with external programmer In case you want to remove the USB bootloader, need to re-install it, or want to use a different MCU, the board has pads to install a 2×5-pin header that is compatible with the mikroProg for PIC.
USB-UART An FTDI virtual serial port driver chip allows you to communicate with a PC or other UART device using a USB-UART connection. RX and TX LEDs indication communication status.
Port headers Each MCU pin is available for further connections through four IDC10 headers with clearly marked pins. There are more than 70 add-on modules with matching IDC10 connectors that you can plug into these headers.
Protoyping area The general-purpose prototype area allows you to expand your Ready for PIC board with additional functions by placing your own components into available soldering pads. The pads are arranged in standard 100mil spacing. There are 30 groups of six connected pads, two groups of 13 connected power pads (GND and VCC), and 186 unconnected pads.
Optional plastic enclosure The board has mounting holes for placing it into a plastic enclosure which is available as an option. The enclosure exposes the USB port and the power barrel connector. The picture to the right shows what the enclosed system looks like.
Software Examples The included DVD-ROM contains several software examples, both as ready-to-load compiled code and as source code written in C, BASIC and Pascal. The source codes provide detailed explanatory comments. Peripheral modules recommended to use these examples are: Potentiometer Board, EasyLED, 128×64 GLCD Adapter, 128×64 GLCD, Alphanumeric LCD Adapter, 2x16 Alphanumeric LCD, Port Expander Board, Easy PS/2 Board.
