Introduction

The EM510 "MiniMo" (R) device is a miniature stand-alone BASIC-programmable embedded module, designed to be used in combination with a standard LED/magnetics RJ45 jack. The combined footprint of the EM510 and a standard RJ45 jack is only 28.5x18.5mm.

The module's hardware mix, which includes 10/100BaseT Ethernet port, a serial port, and 8 GPIO lines, has been carefully tailored to address the basic needs of lightweight IoT devices. If your application has a need to store data in files, an external flash IC can be connected to the EM510. By connecting the WA2000 add-on module to the EM510 you can also enable Wi-Fi and BLE (Bluetooth Low Energy) communications.

Compact dimensions, innovative space-saving "vertical slice" mechanical design, low power consumption, and patented dual-function LED control lines make the module an excellent fit for miniature, cost-sensitive IoT designs.

The EM510 is fully supported by TIDE software and a dedicated EM510 platform that covers all hardware facilities of the device (see TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual). For convenient testing and evaluation Tibbo offers the EM510EV development system.

The EM510 can be ordered standalone or in combination with an industry-standard RJ45 jack and other discrete components required to complete a working circuit.

EM510 advantages over the EM500 module

The EM510 is a higher-performance upgrade to our EM500 device. Here is a small list of important improvements:

  • 32-bit architecture (vs. 8-bit architecture of the EM500).
  • 17 to 33 times better performance, depending on the calculations and variable types.
  • 8 times faster GPIO manipulation.
  • 2.3 times lower power consumption (110mA vs. 260mA).
  • Added support for BLE (Bluetooth Low Energy) communications (this requires the WA2000 add-on).
  • Added suppport for WPA and WPA2 Wi-Fi security modes (Wi-Fi communications rely on the WA2000 add-on).
  • SSI (SPI and I2C communications) object included.
  • The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000 and an iOS or Android device).
  • 20 - C lower internal running temperature (52 - C vs. 73 - C).
  • Industrial operating temperature range (-40 ~ +85C).

Hardware features

  • 32-bit architecture.
  • Powered by Tibbo OS (TiOS).

  • 10/100BaseT auto-MDIX Ethernet port (automatic detection of "straight" and "cross" cables). Standard Ethernet magnetics are NOT integrated into the module.

  • Optional Wi-Fi interface (requires the WA2000 add-on module to be connected).

  • Optional BLE (Bluetooth Low Energy) interface (requires the WA2000 add-on module to be connected).

  • One serial port (CMOS-level):

    • Baudrates of up to 460,800bps;
    • None*/even/odd/mark/space parity modes;
    • 7*/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.

  • 10 general-purpose I/O lines; 2 lines can work as interrupts.

  • 16.1KB SRAM for Tibbo BASIC/C variables and data.

  • 512KB flash memory for TiOS and application code (224KB for application code).

  • Optional 1MB flash disk (requires an external SPI flash IC).

  • 2048-byte EEPROM (2016 bytes are available for the application's data storage).

  • Three control lines for status LEDs:

  • Reliable power-on/brown-out reset circuit (external reset IC not required).

  • Power: 110mA @ 3.3V (100BaseT mode).

  • "Vertical slice" form factor.

  • Dimensions (HxWxT): 16 x 18.5 x 6.5mm.

  • Operating temperature range: -40 ~ +85C.

  • Firmware and compiled Tibbo BASIC/C app can be updated through:
    • The serial port;
    • Ethernet LAN; or
    • Over-the-air (this requires the WA2000 and an iOS or Android device).
  • Tibbo BASIC/C application can be debugged through the Ethernet LAN (no additional debugging hardware is required).
  • CE- and FCC-certified.

* The EM510 does not support the combination of 7 bits/character mode and the "none" parity mode.
