The "MuIn" PIC18F2520 Interface Board is equipped with a powerful PIC18F2520 running at 40MHz. It comes preloaded with a bootloader for serial programming and upgrading, and a firmware full of features. The MuIn can drive two H-Bridges with two PWM channels and two Enable I/O. It can read up to five analog devices such as temperature sensors, potentiometers, distance sensors, etc. with a 10-bit resolution. With Port B it can drive 4 or 8 R/C servos or it can read or write 4 or 8 I/O ports. With the I2C bus you can control almost any I2C device, sending the commands through the serial connection.
Note: The photo to the right shows an XBee module installed for illustration purposes only. An XBee module is not included.
With special commands, you can easily read almost all Devantech I2C sensors and devices. With the free Graphical User Interface, you can program the device ID with a mouse click.
There are several ways to send and receive data to and from this PIC board. Thanks to its socket, you can use an XBee module to make a ZigBee connection. With an XPort module, you can make an Ethernet connection and talk to the PIC board through the Internet or a LAN. With the USB to Serial Micro Converter, you can easily connect the PIC board to your PC USB port.
Last but not least, the firmware is made to be compatible with the free version of the Microchip C18 compiler and it is Open Source (for non-commercial use).
