Microchip 28 pin pic, proto kit - usb, RS232, ICD2 etc.
PIC28 - Prototyping Kit for 28 pin Microchip PIC microcontrollers.
Examples:- 16F876, 18F252, 18F2520 & 18F2550 etc. etc.
Ideal for the 18F2550 - the kit allows easy prototyping of this USB part too.
Everything shown in the picture is included in the kit except the PIC micro. This item is supplied as a kit of components together with a high quality PCB.
The crystal supplied can be 4MHz or 10MHz if specified when ordering, otherwise 4MHz will be supplied. We use 4MHz for USB with the 18F2550. The 4MHz crystal is multiplied to 96MHz inside the PIC and then divided to 48MHz for the USB peripheral and microcontroller core clocks. Many other crystal and divider combinations are possible, please see the PIC data sheet.
The PCB is a high quality Gold Plated double sided PTH (plated through hole) 1.6mm FR4 (Fiberglass) board 76 x 65mm 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.
Ports A, B and C are available on pads to the side of the PIC next to the prototyping area.
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 2 pins. The RS232 interface can be disconnected from the PIC using jumper links.
The USB socket can be disconnected from the PIC using jumper links, this would be useful if using a non USB PIC, but powering from a USB cable.
The 470nf USB decoupling capacitor can be disconneted from the PIC using a jumper.
