EM1206 BASIC - programmable Ethernet module.
The EM1206 is a miniature BASIC-programmable plug-in module. In combination with the RJ203 (jack / magnetics) connector, the EM1206 takes up only 34.5x19mm of PCB space. EM1206 can be used with any suitable ethernet connector.
The module includes a 100Base / T Ethernet interface, 4 serial ports, a flash disk, an EEPROM, and a RTC (real time counter). Thus, the EM1206 is ideally suited for embedding in end products, such as sensors, magnetic card readers (card resaders) connected to the network, drives, and other devices.
The EM1206 optionally supports Wi-Fi connections (WA1000 is required for this), as well as the possibility of external connection of the LCD display, keyboard, and sound source.
EM1206 can be ordered separately, as well as in conjunction with the RJ203 module.
