3.5G Module Upgrade

Overview

The 3.5G module employs the U-blox SARA-U280 GSM module and is compatible with GSM carriers in North America such as AT&T, T-Mobile and MVMO carriers employing these networks.

The form factor of the 3.5G module is identical to the 2.5G module, allowing any RaceCapture/Pro MK2 system to be upgraded. This guide steps you through the process to upgrade RaceCapture/Pro MK2 to the 3.5G cellular module.

Module Identification

  • Top: The 3.5G module, identified by the U-Blox logo.
  • Bottom: The 2.5G module, identified by the SIM900 designation.

Identification in Firmware

To identify a 3.5G vs 2.5G module, power-cycle RaceCapture/Pro and observe the logfile output. Look for cellular initialization messages

  • 2.5G: Cellular initialization messages begin with [SIM900]
  • 3.5G: Cellular initialization messages begin with [ublox]

Compatibility Notes

  • This 3.5G module is compatible with RaceCapture/Pro MK2 only.
  • Currently, the 3.5G module is intended for North America Markets only (United States, Canada, Mexico)
  • The existing 2.5G module will remain available for worldwide operation.

Installation

Disassembling RaceCapture/Pro

  • Using a torx T1 bit, carefully remove the screws from the LED end of RaceCapture/Pro.
    • Do this slowly with a hand tool to prevent stripping of threads
  • Unscrew and remove the gold SMA antenna nuts and washers from the GPS and cellular antenna connections.
  • Remove the end plate
  • Remove the board assembly from the enclosure.
    • You will need to pop the green terminal block free from the opposite end plate as it is a tight fit, by design.

Install 3.5G module

  • Remove the SIM card if necessary.
  • Gently pry the module away from the base board one side at a time until it is free from the socket on either side of the board.
  • Remove the new 3.5G module from the pouch and stow the 2.5G module into this pouch. Set the 2.5G module aside.
  • Install the the 3G module onto the same sockets of the RaceCapture/Pro board
    • Ensure the pins are plugged in on both sides
    • Ensure both sides are plugged in evenly, with no overhanging pins
    • When installed, front edge of telemetry module board should be exactly parallel to main board of RaceCapture/Pro.

Re-installation

  • Slide the assembly back into the enclosure, sliding the board into the bottom rail slot
  • When the board reaches the opposite end, you may need to use a tool to press down onto the green terminal block to ease it back into the machined cut-out.
  • Once the board is installed, re-install the end plate
    • Ensure the flanges are re-installed, if necessary
  • Using the new screws provided, carefully hand thread the screws until you engage the existing threads, then carefully screw in the rest of the way using a hand tool.
    • It's important to avoid cross-threading the screws as the aluminum is delicate
  • Re-install the SMA washers and nuts. Torque the nuts to 3-5 inch/pounds
    • Do not overtighten nuts

Firmware support

The 3G module requires 2.9.x firmware or later. RaceCapturePro_Downloads#Firmware

  • Ensure your configuration is backed up before upgrading firmware

Testing

  • Re-insert your SIM card and follow the testing procedure in our telemetry quick start guide.
    • Note: the 3.5G module does not require constant 12v for operation, it can be tested via USB power alone.

Re-installation into car

  • Re-connect connectors, antennas, and terminal block and install as before.
