The mbed Microcontroller is a 32-bit ARM processor with a comprehensive set of peripherals and a built-in USB interface, all provided in a small and practical DIP package.
This mbed Microcontroller is based on a Cortex-M3 Core running at 96MHz, with 512KB FLASH, 64KB RAM and a load of interfaces including Ethernet, USB Device, CAN, SPI, I2C and other I/O.
- 40-pin DIP package
- 0.1. pitch, 0.9. pin spacing
- 54mm x 26mm
- Powered by USB or 4.5v – 9.0v appiled to VIN
- <200mA (100mA with Ethernet disabled)
- Real-time clock battery backup input VB
- 1.8v – 3.3v Keeps Real-time clock running
- Requires 27uA, can be supplied by a coin cell
- 3.3v regulated output on VOUT to power peripherals
- 5.0v from USB available on VU (only available when USB is connected!)
- Current limited to 500mA
- Digital IO pins are 3.3v, 40mA each, 400mA max total
- Vin – External Power supply to the board
- 4.5v-9v, 100mA + external circuits powered through the Microcontroller
- Vb – Battery backup input for Real Time Clock
- 1.8v-3.3v, 30uA
- nR – Active-low reset pin with identical functionality to the reset button.
- Pull up resistor is on the board, so it can be driven with an open collector
- IF+/- – Reserved for Future use
This is my mbed attached to a development board.
So far, I have programmed my mbed to…
- Send a tweet to twitter (See http://bit.ly/hml7EX)
- Act as a VT100 terminal (Only sent data to my Mac so far)
- 16×2 LCD panel clock
I will upload some more photos soon, and possibly some video.
