mbed baseboard

Remember the terrific mbed devkit we talk about a few days ago? Check out this mbed-compatible baseboard!

The LPCXpresso Baseboard (from Embedded Artists) makes it possible for you to get started with experiments and prototyping immediately. The Base board can also be used together with the mbed module.

• Socket for LPCXpresso and mbed module
• 50 pin expansion dual row pin list connector (male, 100mil pitch) for simple connection external designs and to a logic analyzer
• 50 pin expansion dual row header connector (female, 100mil pitch) for simple connection to breadboard
• Battery powering (small coin battery)
• USB interface
• Reset pushbutton
• RGB-LED (can be PWM controlled)
• 5-key joystick switch
• 2 pushbuttons, one for activating bootloader
• Rotary switch with quadrature encoding (timer capture)
• Temperature sensor with PWM output (timer capture)
• Trimming potentiometer input (analog input)
• PWM to analog LP-filtering (PWM output and analog input)
• Speaker output (PWM output)
• Oscilloscope probe inout stage
• Shift register driving 7-segment LED
• SD/MMC memory card interface
• Dataflash SPI-NOR flash
• PCA9532 port expander connected to 16 LEDs
• 8kbit E2PROM
• MMA7455L accelerometer with I2C interface
• Light sensor
• SC16IS752 - I2C/SPI to 2xUART bridge; connected to RS232 full-modem interface and one expansion UART
• 128x64 pixel white OLED (alternative I2C/SPI interface)
• USB-to-serial bridge, with automatic ISP activation
• RS422/485 interface, connected to DSUB
• Interface socket for XBee RF-module
• CAN bus interface (can be simulated with LPC-Xpresso), connected to DSUB
• Ethernet RJ45 connector with integrated magnetic

All this is powered by 5V USB cable.

Read more and order at LPCXpresso Base Board pages. (But they are currently out of stock, so you have to preoreder...)
