Programmable IoT Module T

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).

• 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.
