EM1206 BASIC-programmable Ethernet Module

The EM1206 is a miniature BASIC-programmable embedded module. In combination with the RJ203 jack/magnetics, the EM1206 occupies only 34.5x19 mm of board space. Alternatively, the EM1206 can be used with any suitable magnetics and jack.

	RJ203+EM1206

The module's hardware mix, which includes 100Base/T Ethernet, four serial ports, flash disk, EEPROM, and RTC, has been carefully tailored to address the typical needs of network-enabled control applications.

This makes the EM1206 especially suitable for "connected" edge products such as sensors, network-enabled card readers, actuators, and other lightweight devices.

The EM1206 can also support Wi-Fi communications (this requires GA1000 add-on board), as well as external LCD, keypad, and buzzer.

The EM1206 can be ordered standalone or in combination with the RJ203 module.

Not available in the U.S.
