Can BB0703 (PICkit 2) work with board designed for ICD2?

Author: Chaonan Chen, Au Group Electronics
The Au Group Electronics BB0703 can work directly on target board designed for ICD2 with a RJ12 6-pin reverse cable (Part#:CBL-RJ12-RVS).

Note: The BB0703 (PICkit 2) is designed based on the Microchip-recommended-schematic. So the BB0703 (PICKit2) RJ12-Connector ICSP- pinout-sequence is reversed comparing with ICD2.

The following table (table 1) shows the RJ12 connector pin-out of Microchip ICD 2 and BB0703 (PICkit 2):

Table 1

Pin number	MPLAB ICD2 RJ12 Connector Pin-out Signal	BB0703 (PICkit 2) RJ12 connector Pin-out signal
1	Not used	MCLR/Vpp
2	PGC	VDD
3	PGD	Ground
4	Ground	PGD
5	VDD	PGC
6	MCLR/Vpp	Auxiliary

The reversed signal doesn't prevent BB0703 from being compatible with ICD 2, a RJ12 6-pin reversed cable can be used to connect BB0703 with any target board designed for ICD2 (as show in Figure 1).

Both RJ12 6-pin standard cable (Part#:CBL-RJ12-STD) and RJ12 6-pin reverse cable (Part#:CBL-RJ12-RVS) are available here at AU group Electronics.

Since Jan-2008, the RJ12 6-pin reverse cable has been added as a standard equipment in the BB0703 system.
