PIC40 - Prototyping Kit for 40 pin Microchip PIC microcontrollers.

Examples:- 16F877, 18F452, 18F4520 & 18F4550 etc.With regard to the 18F4550, the kit allows easy prototyping of this USB part too.

Everything shown in the picture to the right is included in the kit except the PIC micro. The crystal 4MHz and 20MHz will be supplied. We use 4MHz or 20MHZ for USB with the 18F4550.

The PCB is a high quality double sided PTH (plated through hole) 1.6mm FR4(Fiberglass) board 89x80mm in size.It incorporates a large prototyping area with pads on both sides of the board.

The 5V power supply for the PIC can be selected to be from the on-board 5V regulator, the Microchip ICD2 or USB, both the +5V and 0V power rails are extended along the top & bottom edges of the board for easy access.Click Here for larger picture in new window

An onboard RS232 level converter buffers the PIC UART to/from the 9 pin D connector, which is tracked for connection to a PC serial port. The RTS & CTS lines are also buffered and brought to CN9. The RS232 interface can be disconnected from the PIC using jumper links in CN6.The USB socket can also be disconnected from the PIC using jumper links in

CN6, this would be useful if using a non USB PIC, but powering from a USB cable.

A5 pin programming header is also provided to allow in-circuit programming from other programmers e.g. the MELABS serial or USB programmers.The 470nf USB decoupling capacitor can be disconneted from the PIC using CN7.In addition there is a connector for a standard LCD display together with a

contrast variable resistor, the display is tracked to the lower nibble of Port
D, R/W is grounded for write only, and the RS and E signals are left
uncommitted and available on pads for connection to any port pin.

  All port pins are made available to the left of the microcontroller for easy access.
