The Hammer Carrier board is a prototype board designed for use with the 40-pin ARM9 Hammer CPU board.  The board contains a power supply circuit, RS232 serial port, USB host port, USB slave port, a SD/MMC memory card connector, beeper circuit, and a large user prototyping area on 0.100 inch grids.

Features:

• 40-pin machined DIP socket that accepts the Hammer CPU board
• DC power jack that accepts an external 5VDC regulated power supply (2.1mm center positive)
• LM1117 3.3V@800mA voltage regulator for use in the prototyping area
• RS232 connector - DB9 female
• RS232 transceiver circuit for console communications (2nd port is also available)
• User controlled LED  (tied to a GPIO pin on the Hammer)
• User controlled push-button switch (tied to an interrupt pin on the Hammer)
• Reset push-button switch
• Four mounting holes
• Board fits into a PACTEC CM5-125 standard case (available from Mouser Electronics)
• Large user prototyping area (0.100 inch grid)
• Signals from the Hammer CPU board are brought out to the user prototyping
• +5V , +3.3V, and GND  busses are available in the prototyping area
• Open hardware – complete schematic diagram is available below

Dimensions: 4.75” x 4.065”
