Introduction

The Equestic SaddleClip from www.equestic.com is a sensor that aids in the training of horses.

The USB Micro-B charging connector can easily be damaged by mis-insertion of the charging cable.

The lithium battery can also be replaced.

This guide covers disassembly of the product, replacing the USB connector and battery, and reassembly of the product.

    • The hinge pin needs to be pressed out to remove the clip

    • The overmoulded rubber hides one side of the pin as shown in the picture.

    • Align a sharp pointed driver or pin over where the end of the pin is hidden.

    • Gently tap the driver or pin with a hammer until the opposite end protrudes far enough to grip with pliers

    • Grip the protruding pin with pliers and pull it out

    • Using T8 driver remove the two screws on the back of case.

    • The hinge block and front panel (with the 'eq' logo) should now feel loose - but is not removeable yet.

    • There are two hidden clips approximately circled in yellow.

    • Two options for removing panel

    • If you have two thin pins you can try inserting them where the orange arrows are in the first image, through the orange slots in the second image.

    • Or you can gently pull the panel on an angle in the direction of the indicator LED until the clips disengage.

    • The clips and retainers are shown in the second and third images.

    • The hinge block highlighted in green (with the screws removed in step 3) feels loose, but is still retained with 2 clips

    • If you look down inside the open front, you can just make out two triangular clips located in the yellow circles. These clips hold the hinge block to the PCB.

    • Using some sharp tweezers gently release the pcb clips and the hinge block will release.

    • The Li-Ion battery holder is visible on one side, along with the USB Micro-B connector that in this case has been damaged.

    • USB Connector is a Wurth Electronics part #629105136821

    • Battery is a LIR2450 3.6V 120mAh rechargeable Lithium-Ion button cell.

    • The other side of the PCB shows the main components including:

    • CC2640: Texas instruments wireless MCU with Bluetooth

    • MX25L3233FM2I-08G: Macronix 32Mbit Serial Flash

    • MPU-6500: InvenSense 6-Axis motion tracker (3-Axis Gyroscope and 3-Axis Accelerometer)

    • Repair and replace as required for your circumstances.

    • In this case the USB connector is replaced and reinforced as the locating pads have pulled off the PCB.

    • Note that only pins 1 and 5 are used (VBus and GND). No data connection is present.

    • Follow these instructions in reverse order to reassemble the Equestic SaddleClip

    • Note that the battery must be installed before the PCB screws.
