MOXA MiiNePort E3 Embedded Serial Module


Moxa’s MiiNePort E3 Series embedded device servers are designed for manufacturers who want to add sophisticated network connectivity to their serial devices with minimal integration effort. The MiiNePort E3 is empowered by the MiiNe, Moxa’s second-generation SoC, which supports 10/ 100 Mbps Ethernet, up to 921.6 kbps serial baudrate, a versatile selection of ready-to-use operation modes, and requires only a small amount of power. By using Moxa’s innovative NetEZ technology, the MiiNePort E3 can be used to convert any device with a standard serial interface to an Ethernet-enabled device in no time. In addition, the MiiNePort E3 is a compact embedded device server with an RJ45 connector, making it easy to fit into virtually any existing serial device. 

Moxa’s Second-Generation SoC

The MiiNe was created to provide manufacturers with a competitive embedded serial-to-Ethernet solution. The MiiNePort E1, which uses the MiiNe for its SoC, is one of the world’s tiniest embedded device servers and has the lowest power consumption of any similar product. The MiiNe has the following features:

• Designed for 1 or 2-port serial-to-Ethernet applications
• Uses a 32-bit Arm 7 core
• Uses Moxa’s own advanced UART technology
• 2 MB Flash and 4 MB SDRAM memory built in




  • IEEE 802.3af compliant PoE passthrough
  • Use Moxa’s high-quality and reliable second-generation MiiNe SoC
  • Variety of operation modes fulfill specific application requirements
  • Green design with extremely low power consumption
  • MiiNePort NetEZ technology makes integration incredibly easy
  • Highly compact embedded device module
