1. INTRODUCTION/OVERVIEW

SK40C is another version of 40 pins PIC microcontroller start up kit. It is designed to offer an

easy to start board for PIC MCU user. However, all interface and program should be

developed by user. This board comes with basic element for user to begin project

development. It offers plug and use features. This kit is designed to offer:

●Industrial grade PCB

●Vin: 7 to 15VDC

●Every board is being fully tested before ship to customer

●Compact, powerful, flexible and robust start-up platform

●Suitable for hobbyists and experts

●Save development and soldering time

●No extra components required for the PIC to function

●All I/O pins are nicely labeled to avoid miss-connection by users

●Connector for UIC00A/B (low cost USB ICSP PIC Programmer) - simple and fast

method to load program

●Fully compatible with SK40B

●No more frustration to plug PIC out and back for re-programming

●Perfectly fit for 40 pins 16F and PIC18F PIC, the 8-bit PIC.

●With UIC00A/B, program can be loaded in less than 5 seconds

●More convenient to use and it is smaller than SK40B.

●Maximum current of 5V voltage regulator is 0.5A.

●Dimension: 85mm x 55mm

SK40C come with additional features:

●2 x Programmable switch

●2 x LED indicator

●Turn pin for crystal. User may use others crystal provided.

●LCD display (optional)

●UART communication

●USB mini B receptor on board.

●PICkit ICSP 6-pin port which can be used with UIC-A and PICkit 3

●And all the necessities to eliminate users difficulty in using PIC

Users are able to utilize the function of PIC by directly plug in the I/O components in

whatever way that is convenient to user. With UIC00A/B connector on board, user can start

developing projects and have fun with this kit right away. This kit comes WITHOUT PIC

microcontroller to provide the freedom for user to choose PIC type.

This document explains the method to use SK40C.

Side View

1. Connector for UIC00B Programmer

2x5 box header for UIC00A/B, USB ICSP PIC Programmer.

2. JP10 for PICkit

JP10 port reserved for PICkit programmer. User may use PICkit3 and plug to this port and

utilize the ICSP pin to load program besides using UIC00B.

3. UART connector

Reserved for UART communication. Tx and Rx pin of SK40C are connect to RC6 and RC7

respectively. Ensure PIC Microcontroller chosen has the correct UART pin (RC6 and RC7).

4. LED Indicator

2 LEDs (connected to RB6 and RB7) as active High output for PIC MCU. These LEDs are

controllable from PIC MCU.

5. Programmable Push Button

2 x Push button (Tactile switch) connected to RB0 and RB1 of PIC MCU. This is extra input

button for user. It can be programmed as input switch.

6. Reset Button

Push button with the function of Reset for PIC MCU.

7. 40-Pin IC socket for PIC MCU

40 pin IC socket for user to plug in any 40 pin PIC MCU (8-bit and 5V operated). It can either

be 16F or 18F PIC. Of course the IC package should be PDIP.Please ensure the first pin is

at the top side. Inside IC socket, there some electronics components.

8. LCD Contrast

5K of trimmer to set LCD contrast.

9. JP9 for USB

JP9 is provided for USB usage. Connect these pins if user uses USB communication. Shorting

ROBOT . HEAD to TOE

Product User’s Manual –SK40C Rev2.0

both these pins will connect pin 18 of PIC (VUSB on PIC18F4550) to 1uF capacitor. This

setting is necessary if USB peripheral is needed.

10. JP8 for LCD Backlight

JP8 is provided for LCD Backlight. LCD will have backlight if these pins are shorted.

11. Turn pin for crystal

Turn pin is provided for crystal. 20MHz is default crystal comes with SK40C. However, the

20MHz crystal can be removed and replace with other crystal. Just remove the crystal and put

other crystal on turn pin without soldering.

12. Female Header

Female header provides connector for user to make connection between SK40C to prototype

board and utilize the I/O of PIC MCU. It is fully compatible between SK40B. 40 pins of PIC

MCU including OSC (connected to crystal) are extended out to these pin. There is an extra

pin on top of MCLR which is labeled as Vin, is connected to the input power.

13. Parallel LCD pads

Reserved for 2 x 16 character parallel LCD. User may solder 2x16 LCD at these pads if it is

needed.

14. DC power adaptor socket

DC power adaptor socket for user to plug in DC adaptor. The input voltage should within 7 to

15VDC.

15. USB Connector

A USB Mini B receptor. USB connector for communication between devices and a host

controller (usually personal computer or laptop). This function is only valid for certain model

of PIC microcontroller. Please refer to USB interface section. The USB connection also

provides 5V from USB port (computer or laptop or 5V charger) to the SK40C. The power

LED will light ON when the USB cable is connected.

16. Power indicator LED

Power indicator LED for on board power. It will light ON when the 5V voltage regulator

output power or it receives 5V from USB.

17. Toggle Switch for power supply

Toggle switch to On/Off the power supply from DC adaptor.
