Need 3.3 volt, need RS232 with a MAX3232, so took a half build Red Bokito board and put the BTM-112 bluetooth module on it. Is working very well. Now searching for a complete datasheet, the one I have has only 9 pages. No word about the USB, SPI and the programmable IO pins.

Bluetooth with the BTM-112 module from Rayson. Now from one PC to another PC but in the future from a GPS-module to a AIS-receiver.

Today with the post. The Distinctive Excellence Award from Circuit Cellar. Got some new ideas for the next AVR contest.

The device with the WIZ810MJ-module will be on stand on the Embedded Systems Conference on April 14 at San Jose. With this device we won the Distinctive Excellence Award at the WizNet Circuit Cellar contest. Made a display with all information on it. Just plug the power in and all is up and running.

Together with our local electronicstore ARP and with Theo Kleijn, made a very nice display-board. Atmega88 and Max232 for serial communication. It is a 16 x 2 display with a yellow-green backlight. The Atmega88 has a bootloader so a HEX-file can be send through the serial port to program the microcontroller. No difficult programmer needed.

Got a Distinctive Excellence Award for the WIZ810MJ entry I did in the Circuit Cellar Contest. Later a full documentation on my homepage.
