MJ-1 Module-Jig (Product Code: 0770631)

Introduction

The purpose of this module jig is to provide a method of applying voltage from an exter-
nal power supply when the module is out of its mechanics and to support analysis mea-
surements. Furthermore the MCU software can be flashed into the engine module while
it is out of its mechanics.
The repair jig provides following functions:
• Fused protection
• Overvoltage protection
• Reverse polarity protection
• ESD protection
• Decoupling capacitors
• Access to exposed components and GSM connector
• Access to internal test points (Jxxx)
• BlueTooth coupler
It is intended that the module jig should be used, under all circumstances, where an
external supply to the phone is required while the phone is out of its mechanics.
The supply voltage to the module jig is intended to be: 4.2V nominal.
