Do It Yourself PICkit2 programmer design, Au Group Electronics-CB0703

Would you be interested in moving this into the Workbench Creations blog? I built a much more basic pic programmer in the past, so I think this project would be a good fit. Just contact Moose or me and let us know.

That's a lot of work to go through for a $50.00 item. That is, unless you are doing it for fun. If I wasn't doing some other things and I didn't already have one, I might do it.

Thanks!

Mike

The CB0703 PCB is now on sale for US Dollar 1 cent for PIC fans and students.

Due to the high demand of CB0703, this special price is limited to 1 piece per order.

Now a Rev C version of step by step assembly guide has been released on the web:

Our new "BB0703+128K" and "BB0703+256K" are now available for immediate shipment.

This is the second generation design based on our popular "BB0703" (PICKit 2 based) products.

The "BB0703+128K" and "BB0703+256K" come with all enhanced feature of "BB0703", plus the following new enhanced features:

1. Buck/Boost voltage regulation circuits are now standard on all "BB0703+" family. This feature guarantees the ICSP programming working correctly even when USB power supply dropped down to 3V.

2. Native support of 256K EEPROM on "BB0703+256K", no hardware modification is necessary to take the advantage of 256K memory for programmer-to-go (PTG) feature.

Other major features:

*Full implement of Microchip-recommended PICkit 2 circuits
*plus unique enhanced features such as: external power supply, RJ12 interface, buck/boost voltage regulator etc.
*Well designed hardware, no "Vpp pumping" is required
*Dimension:3" L x 1.72"W x 0.81"H (77 x 43.5 x 20.5 mm)
*Color: PC white or Black
*USB power supply: 5V 100 mA
*USB connector: Type B or Mini-B
*Enhanced extra power supply (Optional): 9V 100 mA, positive center
*ICSP interface: RJ12 6-Pin
*Chip support: baseline (PIC10F, PIC12F5xx, PIC16F5xx), midrange (PIC12F6xx, PIC16F), PIC18F, PIC24, dsPIC30, dsPIC33, PIC32, and Microchip Serial EEPROM products
*A RJ12 6 pin reverse cable included, BB0703+ can work directly with board developed for ICD2/ICD3/RealICE for programming and/or debugging

Here is a tutorial on understanding the PICkit 2 hardware:
http://augroups.blogspot.com/2009/05/understanding-microchip-pickit-2-rev.html
It covers some basic design concept on PICkit 2, such as USB voltage, Vpp Boost, Vdd detection and generation, PGD, PGC and Aux voltage clamping, etc.

Now the 50 mil pogo pin cables are released:
