Interface Defines
Ethernet-1: two-way wireless transparent transmission network port, 4PIN 1.25mm pitch with a buckle carrier
Ethernet-2: two-way wireless transparent transmission network port, 4PIN 1.25mm pitch carrier or direct 4PIN soldering hole
Дадзеныя-UART: bidirectional transparent data serial port, Узровень TTL 3.3V, 3PIN 1.25mm pitch with a snap carrier
Main Antenna: main antenna interface, IPEX carrier
Second Antenna: Інтэрфейс дапаможнай антэны, IPEX carrier. The auxiliary antenna can only be received. When the DLM module is used for communication, it can be double-received or received.

USB: 4Штыфт 1,25 мм носьбіт кроку, not yet open to users.
Канфігурацыя uart: 4Штыфт 1,25 мм носьбіт кроку, 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.
Блок харчавання
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 power supply of 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
Спасылка вядзе: 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.
We can customize the housing for you to create a unique brand for you, and we can also add additional amplifiers to allow for longer transmission distances.
