What components are required for this PCB design?

You need a 4mhz crystal, two 22pf caps, one 4.7k resistor, eight 470 ohm resistors, and some LEDs.

Can I skip the 7805 regulator on this board?

Yes, the 7805 regulator is not necessarily necessary according to the text.

How does the board help visualize pin states?

The board shows pin states on LEDs if the LED jumper is on, making it easy to read.

Does the board reorganize the PIC pins?

Yes, it reorganizes the PIC pins so all pins on the same port are next to each other.

What are the options for easy prototyping interface?

You can use the top holes of the wire wrap sockets on the sides or the wire wrap posts underneath.

Is there space for circuit expansion on this board?

Yes, you can add slight expansion on the right side for a serial interface or other circuits.

Which software is needed to open the board file?

You must download ExpressPCB to open the .pcb file.

What is the cost to order three of these boards?

You can get three boards for $59 total including shipping with the mini-board option.

Summary of PIC development/testing board using PIC16F877 microcontroller

This article describes a bare-bones PCB design for a PIC16F877 development board. It highlights features like pin state visualization via LEDs, reorganized port connections, and versatile prototyping interfaces using wire wrap sockets or posts. The board supports easy power connection and minor expansion. Users can download the ExpressPCB file to order three boards for $59.

Parts used in the PIC16F877 Development Board:

4mhz crystal
Two 22pf capacitors
One 4.7k resistor
Eight 470 ohm resistors
7805 regulator (optional)
LEDs

PIC development/testing board

Here's a PCB design for a bare bones PIC16F877 development board. All you need is a 4mhz crystal, two 22pf caps, one 4.7k resistor, and eight 470 ohm resistors, a 7805 regulator (not necessarily necessary, read below), and some LEDs (you don't need to put all 33 LEDs on, just as many as you need to debug your programs).

this board is useful for project development because:= it will show you pin states on the LEDs (if the LED jumper is on) in an easy to read way (the board reorganizes the PIC pins so all the pins on the same port are next to each other)

= it allows easy prototyping interface with the PIC via either (A) the top holes of the wire wrap sockets on the sides or (B) the wire wrap posts underneath

= allows easy power connection

= allows slight expansion on the right side (can put a small circuit there for serial interface or whatever)

====================
download ExpressPCB (look it up on the net)

download the .pcb file

open the file, click 'layout', click 'order via internet' and you can get three of these boards for $59 total (includes shipping) if you click the mini-board option.
