The Robotis OpenCM 9.04-A is a bare bones robot microcontroller board featuring a 32 bit ARM Cortex-M3.
This microcontroller has the same features as the OpenCM 9.04-C but does not have any headers, connectors or USB cable. It is intended for robot DIY do-it-yourselfers who prefer to solder their own connections.
This tiny robot controller board has a STM32F103CB ARM Cortex-M3 processor with 20 KB of RAM and 128 KB of FLASH. It has 26 external GPIO pins with 10 analog inputs, multiple TTL serial ports, SPI and I2C ports. It also supports the CAN bus and JTAG. Ports are available for connection to 3 pin Dynamixel smart servos.
This microcontroller can be programed in C/C++ using an Arduino like IDE. Programs can be downloaded over USB. A JTAG port can also be used for hardware debugging.
