Power: The power input interface, supports 7~24V wide voltage input, maximum power consumption is less than 3.5W.
USB: 4PIN 1.25mm pitch carrier, not yet open to users.
Config UART: 4PIN 1.25mm pitch carrier, not yet open to users.
The DLM module measures 58x48mm (excluding the dimensions of the interface device extending from the edge of the board), the front device height is less than 3.2mm, the back device height is less than 4.5mm, the board thickness is 1.6mm, and the weight is 31.5g.
Power Supply
The power supply signal is shown in the figure above. The power input is 2 solder holes and supports 7~24V wide voltage input. 4V power supply is provided externally for the power supply of the cooling fan.
Ethernet and Data
Signal Indicator
Ethernet-1 LED: Green, a signal indicator on the network port. The network port will flash when transmitting data normally.
Ethernet-2 LED: Green, network port two signal indicator, the network port will flash when transmitting data normally.
Power LED: red, always on when power is normal
Link LED: The working status indicator of the wireless link. When the module works as a slave node, if the wireless connection with the master node is normal, the indicator will be on. This indicator is invalid when the module is working as the master node.
