Its main chip is the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family. Other key parts include the IXDN602SIA, MPXH6115A6T1, TS2940CP50, MPXH6400AC6U and MP6600GR-Z. By type, the board carries 76 resistors, 35 capacitors, 34 diodes, 22 LEDs, 14 jumpers and 12 transistors.
It belongs with the usb & debug tools designs in this gallery.
From the project
EMS boards powered by Speeduino
The reset button was added as the only reset connection made to the microcontroller to prevent unwanted resets from USB connected devices. There is a caveat to this arrangement though. While the first time a firmware is loaded it will go on without intervention, subsequent times will require the user to hold the reset button down then release the button when the program starts the upload process. If the upload does not start right away go back and try again.
