Hardware

Specifications:

• 32-bit architecture
• Powered by Tibbo OS (TiOS)
• Stores up to two compiled Tibbo BASIC/C binaries (apps)¹
  • A Device Configuration Block (DCB)² defines which of the two apps normally runs on power-up
  • Forced launch of APP0 through the MD line/button
• Built-in Wi-Fi interface (802.11a/b/g/n)
  • Controlled via a simple-to-use, yet sophisticated API
  • TLS1.2 with RSA-2048 cryptosystem³
  • Optional "autoconnect" — automatic association with a designated Wi-Fi network as defined by the DCB²
  • Optional debugging of Tibbo BASIC/C applications via the Wi-Fi interface⁴
• Built-in Bluetooth Low Energy (BLE 4.2)
  • Controlled via a simple-to-use, yet sophisticated API
  • Can access the DCB via a new, integrated console²
• Onboard antenna (U.FL connector for an external antenna on request)
• Two high-speed serial ports (CMOS-level):
  • Baudrates of up to 921,600
  • 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
  • One of the ports can function as a serial debugging port⁵
• 10 general-purpose I/O lines
  • Two lines can work as interrupts
  • Nine lines can provide pulse-width modulation (PWM) output
  • Three lines can work as ADC inputs
• Support for externally connected matrix and binary output keypads
• RTC with dedicated backup power input
  • Only 30µA power draw on the backup power input⁶
• 58KB SRAM for Tibbo BASIC/C variables and data
• 4MB flash for code storage
  • System files and TiOS occupy a combined 2,408KB
  • 1,688KB available for storing up to two app binaries¹
• Additional 4MB flash for the hardened fault-tolerant file system
• 2,048-byte EEPROM for data storage.
• Three onboard status LEDs
  • Green and red main status LEDs/lines
  • Yellow Wi-Fi/Bluetooth link LED/line
• Reliable power-on reset (no brown-out detection)
• Power: 150mA @ 3.3V (Wi-Fi on and scanning)
• Provisions for a deep power-down "sleep" mode
• Dimensions (L x W x H): 45.1 x 28.15 x 3.5mm
• Prototyping-friendly 2.54mm (100mil) pin pitch
• Operating temperature range: -40°C to +85°C
• Firmware and compiled Tibbo BASIC/C apps can be updated via:
  • Serial port
  • Wi-Fi interface
  • Bluetooth Low Energy (BLE) interface
• Tibbo BASIC/C applications can be debugged via Wi-Fi⁴ or serial port⁵
• Supplied with a companion app preloaded
  • The app allows editing of the DCB from the L.U.I.S. smartphone app (availabe for iOS and Android)
  • Users are free to modify the app for additional functionality

1. Although two independent Tibbo BASIC/C compiled binaries (apps) can be stored in the WM2000's flash memory, only one can run at a time.
2. Several of the WM2000's configuration parameters are stored in the DCB, which is accessible via a new integrated console. Our BLE Terminal web app leverages the Web Bluetooth API (compatible with the Chrome, Chromium, Edge, and Opera web browsers) to connect to the WM2000's console. Configuration properties can also be read and set through Tibbo BASIC/C code.
3. TLS is supported on a single outgoing TCP connection.
4. To enable Wi-Fi debugging, you must enable autoconnect — automatic association with a designated Wi-Fi network. This can be accomplished via the integrated console, the companion app, or in code.
5. Only one serial port is available to Tibbo BASIC/C apps when in serial debug mode. If you need to use both serial ports, use Wi-Fi debugging instead. The debug mode can be selected via the integrated console or the companion app.
6. The power draw on the backup power input can vary up to ±15 percent depending on the configuration of the attached hardware.
