iLogger Pinout / Specifications

iLogger is an all in one logging solution for Vesc based ESCs. It has a compact design and supports both CAN and UART protocols.

Hardware specifications: 

  • 2x CAN ports : CAN1 and CAN2. CAN1 connects to CAN port on Vesc, while CAN2 is used to forward CANL and CANH pins to the next node.
  • 1x UART port
  • 1x GPS port: Connects to most GPS based modules and allows location based logging as well as automatic time synchronization.
  • 1x Micro SD card slot: Accepts up to 32GB formatted as FAT32.
  • Orange LED: Power indicator
  • GREEN LED: WIFI indicator
  • BLUE LED: SD Card mount indicator
  • Reset button: Used when upgrading firmware from an SD card, see bellow on how to update.


Before using your iLogger, download the infinity tool app from either Google Play store or iOS test flight:

Google Play Download | iOS App Download

  1. Format your Micro SD as FAT32.
  2. *Always insert or remove SD Card when iLogger is powered off*
  3. If using CAN, enable CAN Status Message Mode and set it to CAN_STATUS_1. Set CAN baud rate to CAN_BAUD_500K. Set CAN Status rate to 50Hz.
  4. If using UART, enable UART app and set baud rate to 115200

Powering Up



  1. If connecting through CAN:
    1. Plug provided CAN cable into CAN1 port and to your CAN port on your ESC. If you have a dual Vesc they are already connected internally. If you have separate units, use the provided CANL/CANH cable and forward from CAN2 port on iLogger to second Vesc.
    2. Power on Vesc, iLogger orange LED should light up.
  2. If connecting through UART:
    1. Plug provided UART cable into UART port of iLogger and to your UART port on “Master” ESC.
    2. If running a Dual Vesc, make sure to plug iLogger to UART port of the Master Vesc, and specify Slave ID on the iLogger settings. Plugging iLogger to Slave Vesc won’t be able to correctly detect devices.
    3. Double check that Tx and Rx pins are correct. Tx pin should go into Rx pin of Vesc, while Rx pin goes into Tx pin. On some Vesc models those are swapped.
    4. Power on Vesc, iLogger orange LED should light up.
  3. If a GPS module is available
    1. Connect GPS to the GPS port and double check that pinout is correct. GPS modules that we sell are tested and have the correct pinout out of the box.

BLE Pairing

Each iLogger module comes with a unique 6 digits pin. If you have lost yours, please contact us at with your order # number to assist you retrieving it.

How to pair BLE:

  1. Power on iLogger, open iTool app.
  2. Wait a few seconds until device appears under Devices tab
  3. Tap on “Connect”. A dialogue will popup to let you enter your 6 digit pin.
  4. After entering your pin, wait a few seconds for the pairing process to finish.



  • There are no prompt notifying you if you enter the pin wrong. If you are having trouble connecting to the module its most likely because of a mistyped pin number. Close the app and restart iLogger, then try again.
  • If the pairing prompt didn’t popup automatically on first connect, go to your Bluetooth devices menu, find iLogger and pair with it manually, then start the app.

Update Firmware

It is very crucial to keep both app and iLogger firmware up to date as new fixes and improvements are regularly added.

There are two ways to update the firmware on iLogger:

  1. OTA (Over The Air Updates)
  2. Manually using SD Card.


Using OTA:

  1. Once you connect to the module through iTool app, a pop up dialog will notify you if a new firmware update is available.
  2. Otherwise, tap on settings, Update, then OTA process will check if a new version is available. If an update is available, it will start automatically and will last between 2-5 minutes to finish. Do not interrupt or power off during that time.
  3. A confirmation dialog will popup if the update was successful and iLogger will automatically reboot, otherwise, an error message will appear explaining why.


Using SD Card:

  1. Download and place update.bin firmware at the root of an SD Card.
  2. Insert SD Card while iLogger is powered Off.
  3. Hold reset button and turn ON ilogger.
  4. Keep holding for 3 seconds then release reset button.
  5. Blue LED will start flashing rapidly indicating firmware is being updated.
  6. Do not interrupt, iLogger will automatically reboot after the update is done.

Configuration Setup

To get started logging Vesc data, and assuming your device is already paired with the iTool app, Tap on “Connect”, wait 3 seconds to initialize and read all BLE characteristics, then tap “Settings”

All device configuration is done under “Settings” tab:

Overal Status values:

  • BLE connection status: Should display “Connected”.
  • iLogger Fw: Displays current firmware ver. of the module
  • Vesc Fw: Displays detected Vesc firmware version
  • Vescs IDs: If multiple Vescs are detected through CAN, their IDs will be displayed here.
  • CAN Receive: Displays CAN communication status.
  • CAN Messages: Displays 1 if iLogger has been able to receive CAN message from Vesc.
  • Wifi: Displays Wifi status along with SSID if connected.
  • GPS: displays GPS status.
  • SDCard: Displays SD Card status and used/total capacity if mounted successfully.


Setup Wifi Button:

Tap on setup wifi and enter access point SSID and password. If no password is required, leave empty. Tap on Ok. Module will auto restart and attempt to connect to WIFI.

If connected successfully Green LED will lit up.

Wifi is used for OTA updates, time and date synchronization and uploading logs to online account.
