Development board for 40 pin Pic Microcontrollers
Large prototyping area
Pickit2 / 3 compatible
On board RS232 level converter
PCB 89x80mm
Compatible PICs include 16F877, 18F452, 18F4520 and 18F4550.
Ideal for the PIC18F4550 (USB) which is available on our components page.
Designed around a high quality Gold Plated PTH (plated through hole) PCB 1.6mm FR4 (Fiberglass) board.
You choose the 5V power supply to come from the on-board regulator, Microchip ICD or USB.
The +5V and 0V power rails are extended along the top & bottom edges of the board for easy access.
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.
You can disconnect the USB socket from the PIC using jumper links in CN6, useful if you’re using a non USB PIC, and powering from a USB cable.
A 5 pin programming header is also provided to allow in-circuit programming from other programmers e.g. the MELABS serial or USB programmers. Microchip Pickit 2 and PicKit 3 programmers can be connected via the ICD connector using an adaptor cable available on this page.
The 470nf USB decoupling capacitor can be disconnected from the PIC using CN7.
You get the option of 4MHz or 10MHz crystal to be supplied: please specify when ordering, otherwise 4MHz will be supplied. We use 4MHz for USB with the 18F4550. 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.
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.
A suitable LCD display and ready made ribbon cable are available below
