The EM2001 is a full-featured Tibbo BASIC/C-programmable IoT Board with Ethernet, as well as optional Wi-Fi* and GPRS** connectivity. The EM2001 has four UARTs. The board offers substantial speed and functionality improvements over its predecessor — the original EM1001 device.

The board is self-sufficient — it does not require a host PCB to plug into. The RJ45 jack is mounted directly on the board. The EM2001 also contains a DC-DC regulator that can power the board and has additional current budget for external hardware.

The device's capabilities are further enhanced by the onboard flash memory with hardened fault-tolerant file system, as well as the EEPROM and RTC with backup battery.

The EM2001 has 56 general-purpose I/O lines and can control an external LCD, keypad, buzzer, card readers, serial devices, and other circuitry. All I/O lines are accessible through two dual-row connectors with the standard 2.54mm (100mil) pitch.

The board may be uploaded with a fully functional serial-over-IP (SoI) application that turns the EM2001 into a powerful serial over IP (SoI) device, a.k.a. the Ethernet converter.

The EM2001 is a close relative of the EM2000 IoT module.

* Requires the GA1000 Wi-Fi add-on, which can be connected externally or piggybacked on top of the EM2001.

** Requires a standard GPRS modem (i.e. Simcom's SIM900), to be connected to the UART #4 of the EM2001.

  • Software-controlled PLL allows to select full, medium, or low speed.
  • Reliable power-on/brown-out reset circuit.
  • Powering options:
    • Through the switching regulator, 12VDC nominal (8 ~ 20V);
    • Using regulated 3.3V power (the regulator is bypassed).
  • The regulator can provide up to 1.3A @ 3.3V to external devices.
  • Power: 100mA @ 3.3V (100Base-T mode, full speed).

  • Operating temperature range: -40 ~ +80°C.
  • Firmware is upgradeable through the serial port or network.
  • *Must be connected externally.

    **The EM2001 does not support the combination of the 7 bits/character mode and the "none" parity mode.

    ***Not including RJ45, power jack, GA1000.
