CBL-0703-POGO: PIC In-Circuit Serial Programming (ICSP) Pogo Cable

Au Group Electronics
Author: Huihui Duan, Chaonan Chen, Au Group Electronics

Au Group Electronics BB0703 PIC In-Circuit Serial Programming (ICSP) Pogo Pin Cable (part#:CBL-0703-POGO ) is designed for Au Group Electronics BB0703 family products.
Three different colors in fixture are available: blue, white, and black. Samples are displayed in Figure 1 below.
(Note: actual product's color and style may be changed without further notice; all pictures in this document are for demonstration purpose only.)
Figure 1 CBL-0703-POGO

Specification:
Current rating: 3 amps continuous
Spring force: 4.0 oz each pin @ 0.100 inch working travel distance
Typical contact resistance: less than 60 mOhm
Working travel distance: 0.100~0.160 inch
Pogo pin Material: BeCu with gold plated


When CBL-0703-POGO is connected with Au Group Electronics BB0703 and BB0703+ family products, the ICSP signals are defined as table 1.

Note 1: The Pin-out and wire color listed in table 1 is for BB0703 family only. When other PIC programmer products are connected, these signal definition may be different.
Note 2: The "pin # 1" indicator (triangle) (figure 2, figure 2-1) or pin numbers are located on the pogo pin fixture in different pattern (figure 2-2) (Note: All dimension are for reference only, actual product may be changed without further notice.)

Note 3: Recommended PCB pads pattern (mating with pogo pins) is shown in figure 3, recommended parameters are: ID = 1 mm, OD = 2mm, and pin pitch = 2.54 mm (100 mil).

Note 4: This cable is also capable of being used with other PIC programmers (e.g. Microchip ICD2/ICD3/RealICE, etc.), please be aware that each programmer's ICSP pin-out definition may be different. When CBL-0703-POGO is used with non-BB0703 programmer, please always refer to the programmer's specification for correct pinout.

When CBL-0703-POGO is connected with ICD2, the ICSP signals are defined as table 2
When CBL-0703-POGO is connected with ICD3, the ICSP signals are defined as table 3.
