EM2000 Programmable IoT Module

The EM2000 is a full-featured Tibbo BASIC/C-programmable IoT Module with four UARTs and Ethernet, as well as optional Wi-Fi*, BLE** (Bluetooth Low-Energy), and GPRS*** connectivity. The module offers substantial speed and functionality improvements over its predecessor — the original EM1000 device.

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

The EM2000 has 56 general-purpose I/O lines and can control an externally attached LCD, keypad, buzzer, card readers, serial devices, and other circuitry.

Device pins have the standard 2.54mm (100mil) pitch. This makes the module ideal for use not only in production devices but also for prototyping.

Module testing and evaluation can be performed on the EM2000EV board. The EM2001board, a close relative of the EM2000, is also available.

* Requires the WA2000 or GA1000 add-ons, which can be connected externally or piggybacked on top of the EM2000.
** Requires the WA2000 add-on, which can be connected externally or piggybacked on top of the EM2000.
*** Requires a standard GPRS modem (i.e., Simcom's SIM900) to be connected to a UART of the EM2000.

Hardware

Specifications:

• 32-bit architecture.
• Powered by Tibbo OS (TiOS).
• 10/100BaseT auto-MDIX Ethernet port (no magnetics).
• Optional Wi-Fi interface (requires the WA2000 or GA1000add-ons).
• Optional BLE interface (requires the WA2000 add-on module).
• Can control a GPRS modem* (such as the SIM900).
• Four high-speed serial ports (CMOS):
  • Baudrates of up to 460,800bps;
  • None**/even/odd/mark/space parity modes;
  • 7** or 8 bits/character;
  • Full-duplex mode with RTS/CTS and XON/XOFF flow control;
  • Half-duplex mode with direction control;
  • Encoding and decoding of Wiegand and clock/data streams.
• 56 general-purpose I/O lines; 8 lines can work as interrupts.
• Square wave output (can be used for buzzer* control).
• 4-channel ADC.
• 4 synchronous serial ports with SPI and I2C modes.
• Supports a 320x240 TFT LCD*.

• Three status LEDs onboard:
  • Green and red main status LEDs;
  • Yellow Ethernet link LED.
• Four control lines for external status LEDs:
  • Two control lines for green and red main status LEDs;
  • Two control lines for Ethernet "link" and "100Mb" LEDs.
• Software-controlled PLL allows selecting full, medium, or low speed.
• Reliable power-on/ brown-out reset circuit.
• Power: 100mA @ 3.3V (100Base-T mode, full speed).
• Dimensions (LxWxH): 38.4 x 28.4 x 5.5mm.
• Prototyping-friendly 2.54mm (100mil) pin pitch.
• Operating temperature range: -40 ~ +80°C.
• Firmware is upgradeable through:
  • The serial port;
  • Ethernet LAN; or
  • Over-the-air (requires the WA2000 and an iOS or Android device).
• Tibbo BASIC/C application can be debugged through the Ethernet LAN.
• CE- and FCC-certified.

*Must be connected externally.

**The EM2000 does not support the combination of the 7 bits/character mode and the "none" parity mode.
