EM2001 BASIC/C-Programmable IoT Board

Introduction

The EM2001 is Tibbo's most powerful and versatile Tibbo BASIC/C-programmable Ethernet board. The EM2001 is a close relative of the EM2000. The two devices have the same feature set, including a 10/100BaseT Ethernet port, four serial ports, onboard flash disk, EEPROM, and an RTC with optional backup supercapacitor. Like the EM2000, the EM2001 can control a WA2000 Wi-Fi/BLE add-on module, as well as an external LCD, keypad, buzzer, and many other peripheral components.

Unlike the EM2000, the EM2001 is a self-sufficient board: it has a 12V-to-3.3V switching power regulator, RJ45 connector with magnetics, three LEDs, and an MD button. Thus, the EM2001 does not require a host board to plug into — it is the host board. As such, the EM2001 is equally suited to low-volume production devices and hobbyist projects alike.

The EM2001 is fully supported by Tibbo IDE (TIDE) and shares the EM2000 programming platform.

EM2001 Advantages Over the EM1001 Board

The EM2001 is a high-performance upgrade to our EM1001. Here is small list of important improvements:

• 32-bit architecture (vs. 16-bit architecture of the EM1001).
• Five to 80 times better performance, depending on the calculations and variable types.
• Seven times faster GPIO manipulation.
• Three times larger available user SRAM (66KB vs. 22KB).
• 1.5-3.0 times faster graphics.
• 2.2 times lower power consumption (100mA vs. 220mA).
• Two times larger flash memory (1MB for TiOS/code + 1MB for the file system vs. 1MB total for TiOS, code, and file system).
• 56 I/O lines (vs. 54 lines on the EM1001).
• Four-channel ADC.
• The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000 add-on module).

• Three status LEDs onboard:
• Green and red main status LEDs
• Yellow Ethernet link LED
• Two control lines for external green and red main status LEDs
• Software-controlled PLL allows selecting full, medium, or low speed
• Reliable power-on/ brown-out reset circuit
• Powering options:
• Through the switching regulator, 12VDC nominal (8V ~ 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 (100BaseT mode, full speed)
• Dimensions (LxWxH): 75 x 36 x 17.5mm⁽³⁾
• Operating temperature range: –40°C to +80°C
• Firmware is upgradeable through:
• The serial port
• Ethernet LAN
• Over-the-air (requires the WA2000)
• Tibbo BASIC/C application can be uploaded and debugged through the Ethernet LAN (no additional debugging hardware is required)
• CE and FCC-certified

1. Must be connected externally.
2. The EM2001 does not support the combination of 7 bits/character mode and the "none" parity mode.
3. Not including RJ45, power jack, WA2000.
