Seeeduino Mega impressions
The Seeeduino Mega is a really neat device. Within the dimension of 71mm*53mm there is a 8bit Atmel1280@16Mhz, equipped with whopping 8KB of RAM and 128KB of flash and 70 I/O pins. The programming is done at PC, using a C/C++ in a bit toy-like IDE. With the help of really simple IDE, and its example applications and system libraries, one can get the LED blinking in an matter of minutes.
On the first inspections I found that the board seems to be fixed with wire cutter at the factory. I assume that the board had some leads connecting at wrong places and they simple cut the joints open, but unfortunately made some scratches over lines too. This was a bit worrying, but closer look with magnifying class and a tests with multimeter revealed no trouble. For testing I used a simple application to turn on and off the PWM-IO-pins
one at time to make sure, that the connections work. Fortunately there is no need to send the device back to supplier, may the play continue.
See the next picture, leftovers of wire cutting at top, right and bottom.
