- The voltage range of TX RX is 7~24V.
- At 12V power supply, use an adapter with a maximum of 1A or more.
- Prepare a formattedFAT32format Micro SD card
- Unzip the upgrade file from our verify and send to you, Here is "1816_update_image_xx_yy.zip" file, and copy it to the root directory of the Micro SD card, pay attention to keep the directory structure unchanged (there is a flash folder in the root directory of the Micro SD card, and there is an app folder in it).
- Insert the Micro SD card into the Vcan1816 module, power on and wait for the red light on the board to flash, indicating that the upgrade is successful.
- Ceeb toom:
Under normal circumstances, the update will be completed within 30s after power-on (the red light flashes). If the red light does not flash for a long time after power-on, please check the connection of Micro SD and try power-on again.
