PIC18F2550 APPLICATION BOARD PCB
Hardware; PIC 18f2550 I/SP microcontroller., 24Cxx EEPROM (I2c communication with), 20 MHz crystal., 6-15V power supply input., 5V 1A regulated output., USB support., ICSP programming, Pin header I/O terminal system
General features and usage
1-USB: USB support is the most important feature of self PIC 18f2550 aygün surgical instruments carried out. In this way, you can have a quick communication with your computer via USB.
2-24Cxx EEPROM with I2c serial communication protocol, communicate with each other on the card: an eeprom.
3-ICSP programmer with ICSP support from microdenetleyicinizi over a: removing the card on the program.
4-5V regulated: regulate the IC Card on the 7805 5v supply is provided through microdenetleyicinizin.
5-ICSP-jumpers J1 and J2 I/O with B6 and B7: ports on demand for ICSP programming or I/O port allows you the choice of using.
6-LVP: J3 jumper is inserted ICSP programming with low voltage mode programming. (Supports Low voltage programming for programmers.)
7-I2c – I/O: J4 and J5 jumpers B0 and B1 ports on demand through the I2c communication is the use of the eeprom or I/O port allows you the choice of using.
8-USB-I/O: J6 and J7 thanks to C4 and C5 ports on demand USB communication jumpers or the ability to use selection as I port.
9. Power Led: indicates whether the + 5v supply.
10-Reset: old Microdenetliyicinin foot pulls MCLR pulls back. Reset the reset is activated from the program.
11-Power Out Terminal: terminal 4 output. One of these 2 GND (negative), and others;
+ V is the same as the voltage is entered into clips on the card:.
+ 5V output voltage circuit is: (max. 1A)
12-Port I/O Terminal: terminal system in all ports with active Mikrodenetliyicinin pinheader is available.
PIC18F2550 BOARD ICSP CONNECTION
On-board supply and the I / O terminals to the top pcb mounting system is designed as a pinhead, according to the template established on their drawings printed circuit boards or perforated plate circuits that can operate easily.
