Due Alternative - SainSmart Land Tiger

Looking through the SainSmart site, I noticed a Cortex-M3 board with many features built in.  And it's priced at $60.99


The Land Tiger development board on-board USB emulator, supports USB 2.0 Device, dual CAN interfaces, RS-485 interface functions. It has many of the features that the Arduino Due chose to leave off their board (like Ethernet).  The touchscreen interface is a nice touch.  And it would appear that it uses the Due version of the Arduino Due for programming.

Features:

  • Cortex-M3 512KB on-chip Flash, to support ISP and IAP
  • 64KB SRAM
  • processing rates 100MHz, and includes a support eight areas of memory protection unit (MPU)
  • Built-nested vector interrupt controller
  • AHB multi-layer matrix with 8-channel DMA controller, general-purpose (GPDMA)
  • support the SSP, UART, AD / DA, timer, GPIO, etc., can be used for memory to memory transfers
  • standard JTAG test / debug interface and debug serial line and serial line tracking port option
  • simulation trace module supports real-time tracking
  • 4 low-power modes: sleep, deep sleep, power-down, deep power-down
  • single 3.3V power supply (2.4V - 3.6V)
  • Operating temperature: -40 °C - 85 °C
  • non-maskable interrupt (NMI) input
  • On-chip integrated power-on reset circuit
  • Built-in systems beat the timer (SysTick), to facilitate the operating system migration.


Onboard Resources:

  • 2-Way RS232 serial interface (using the straight-through serial cable, serial port support them all the way ISP download)
  • 2 CAN bus communication ports (CAN Transceiver: SN65VHD230)
  •  RS-485 communications interface (485 Transceivers: SP3485)
  •  RJ45-10/100M Ethernet network interface (Ethernet PHY: DP83848)
  •  DA output interface (USB sound card can do experiments on-board speaker and speaker output driver)
  •  AD input interface (adjustable potentiometer input)
  •  color LCD display interface (which can take 2.8-inch or 3.2-inch color TFT 320X240)
  •  USB2.0 Interface, USB host and USB Device Interface.
  •  SD / MMC card (SPI) interface (available with FAT12, FAT16, FAT32 file system)
  •  IIC Interface (24LC02)
  •  SPI serial FLASH interfaces (AT45DB161D)
  •  2 user keys, 2 function keys and the INT0 Reset button, 8 LED lights
  •  1 Five keys to enter the joystick (Joystick)
  •  serial ISP download function (no need to set jumpers), the standard JTAG download, simulation debugging interface.
  •  integrated USB emulator: simulation and debug capabilities to support online and support KEIL, IAR and other mainstream development environment.
  •  optional external 5V power supply or USB input to provide 5V power supply.
  •  leads all the IO, user-friendly external circuit to the secondary development of other applications.

I really like it when a board/system designer includes enough of the touches to encourage developers rather than throwing them to the wolves.  This one is rather cool.


Now if SainSmart wants a bigger review, send one over ;-)


While I did post an April Fools post on Google+, this is not an April Fools post.
