New Atmel Boards
¶ MichaelP @ 23:28 
| We just finished testing our new small ATmega2560 boards: | |
 |  |
 | The communications are now done with USB, via an FT2232D, instead of the old RS-485 approach, and it is, of course, bus-powered. What's really novel, however, is that--with a good deal of extra software--we can reflash the chip in-system over the second interface on the FT2232, which saves us the trouble of opening the hull and risking leaks. This means we can try more experimental code. |
 | Of course, it wouldn't be complete without a really bright blue 30mcd LED, drawing 20mA straight off a microcontroller pin (and a few other less-visible LEDs). The board now takes up half the area of the old one, with 99 of the 100 AVR pins routed, and has some really slick 0.05" pitch Samtec headers (except the JTAG, which had to be standard). I'll try to post more once it's actually mounted on the tray. |
