EM500 Single UART Programmable Embedded Module


The EM500 is an ultra compact Tibbo BASIC/C-programmable IoT Module with Ethernet

The first member of our MiniMo family, the EM500 is designed to be used in tandem with a standard RJ45 magnetics jack. The combined footprint of the EM500 and a typical jack is only 28.5×18.5mm (1.12×0.63″).

Compact dimensions, space-saving “vertical slice” form factor, low power consumption, and economical pricing make the module an excellent fit for miniature, cost-sensitive “connected” devices.

Module testing and evaluation can be performed with our EM500EV development system.

The EM500 may be uploaded with a fully functional serial-over-IP (SoI) application that turns the EM500 into a powerful serial over IP (SoI) device, a.k.a. the Ethernet converter.

Key Features:

  • 10/100 Base-T Ethernet port (no RJ45/magnetics)

  • 8 general-purpose I/O lines
  • 512K flash for TiOS and application, support for external 1MB flash disk
  • 208-byte EEPROM
  • Dual-function LED control (using flashing patterns)
  • Height and width of an RJ45 jack,thickness 6.5mm
  • 3,3V power supply
