Summary of PIC 18F – 28 PIN PIC Development Board
This PIC18F Development Board is a cost-effective, versatile platform designed for 18F 28-pin Microchip microcontrollers. It features a ZIF socket for easy MCU replacement, an ICSP connector for straightforward programming, and a plug-in/plug-out 20 MHz crystal controlled by jumpers. The board includes a bridge rectifier for polarity protection, a 7805 voltage regulator for stable power, and labeled port pin headers for external connections and add-on cards. It requires a 7-18V DC supply and is designed for easy development and testing with the PIC18F microcontroller.
Parts used in the PIC18F Development Board:
- 18F 28-pin Microcontroller (PIC18F series MCU)
- ZIF (Zero Insertion Force) socket
- ICSP (In-Circuit Serial Programming) connector
- 20 MHz Crystal oscillator
- Jumpers (J1, J2 for crystal plug-in/out; J3 for RE3 IO pin or VPP selection)
- Bridge rectifier (D2)
- Power On LED (D3)

- Port pin header connectors
- Power supply connector (CN5, DC 7-18V input)
Description
This is a versatile, configurable, and cost effective Development Board designed for the 18F 28 pin series of Microcontroller from Microchip. The board is simplest form with all the Port pins terminating in a header connector for easy connection to the outside world.
Power Supply 7-18V DC
This is a PIC18F Development board with ICSP connector.
Some of the key benefits of this Development board are:
- A ZIF socket enables easy removal of the Target MCU from the development Board.
- Well Marked ICSP for connecter offers easy programming of the MCU on Board.
- Plug In Plug Out type crystal on the development board. Two jumpers J1 and J2 help you Plug In Plug Out crystal from your project. A 20 Mhz Crystal is supplied along with the kit.
- Jumper J3 allows you to use RE3 as a IO pin and VPP for the ICSP connector.
- A bridge rectifier (D2) takes care of any polarity connection at CN5. Power On LED D3 displays Power on the PCB and the Voltage Regulator IC U2 7805 ensures regulated power to the microprocessor and other devices connected to this board.
- All Port Pin Connector are capable of providing DC supply to the ADD ON cards. Please ensure that you calculate your current requirement before sourcing this supply from this PCB. No short circuit protection is provided at these outputs.
Please refer to the schematic diagram for the configuration of this board.
