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* 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 with the 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 prototyping, low-volume production runs, and hobbyist projects.

Module testing and evaluation can be performed with our upcoming EM2000EV board. The EM2001 board, a close relative of the EM2000, is also available.

The EM2000 may be uploaded with a fully functional serial-over-IP (SoI) application that turns the EM2000 into a powerful serial over IP (SoI) device, a.k.a. the Ethernet converter.

* Requires the GA1000 Wi-Fi add-on, which can be connected externally or piggybacked on top of the EM2000 ("EM2000G" ordering code).

** Requires a standard GPRS modem (i.e. Simcom's SIM900), to be connected to the UART #4 of the EM2000.
