How to add the FRAM module to Kraftor

This guide explains how to retrofit the FRAM 1.0 module in a Kraftor. The module is installed on the underside of the main PCB, so the enclosure, optional speech board and display assembly must first be removed.

Before you start

  • Disconnect USB, power and every other cable from Kraftor.
  • Work on a clean, non-conductive surface and take normal anti-static precautions.
  • This retrofit requires careful soldering. If you are not comfortable soldering small electronics, ask a qualified technician to install the module.

What you need

  • FRAM 1.0 module
  • Small screwdriver suitable for the four PCB screws
  • Fine-tip soldering iron and electronics solder
  • Tweezers and a magnifier, if available

Installation

1. Open the Kraftor enclosure

Hold the lower part of the enclosure. Gently pinch both sides of the top cover to release the clips, then lift the cover away. Do not force the plastic.

2. Remove the speech board, if fitted

If a speech board is installed, carefully remove it and put it somewhere safe. The photos show a VaxVox board, but the same step applies to another compatible voice board. Handle the board by its edges.

3. Lift the display assembly

Gently lift the display assembly out of the enclosure. Keep it close to Kraftor at this stage so that the connecting wires are not pulled or strained.

4. Disconnect the display

Disconnect the display assembly from the main PCB. The Grove connector has a small locking tab: press and hold the tab to release the connector, then pull the connector straight out—never pull on the wires.

5. Remove the four PCB screws

Remove the four screws securing the Kraftor main PCB. Keep the screws together for reassembly. Their locations are circled in the photo below.

6. Move the main PCB away from the rear panel

Carefully slide the PCB away from the rear panel and lift it only as far as necessary to reach its underside. Avoid putting stress on the sockets, controls or remaining wiring.

7. Position and solder the FRAM module

Locate the FRAM footprint on the underside of the Kraftor PCB. Position the FRAM 1.0 module exactly as shown, with the module aligned to the footprint and sitting flat against the PCB.

Solder the module to the matching pads on the Kraftor PCB. Use only enough solder to make clean joints, and check carefully for bridges between adjacent pads before reassembly.

8. Reassemble Kraftor

  1. Return the main PCB to its original position and reinstall the four screws.
  2. Reconnect the display exactly as it was before, then place the display assembly back in the enclosure. (You will need to push the wires under the PCB)
  3. Reinstall the speech board, if one was fitted.
  4. Refit the top cover and make sure both sides clip into place.

Reconnect Kraftor and check that it starts and operates normally. If it does not, disconnect it immediately and inspect the FRAM orientation, solder joints, connectors and wiring before trying again.
