NO2C.EVO
About the NO2C.EVO PCB
NO2C.EVO is an open source AVR/Arduino PCB design by turboedge, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 99.4 × 53.7 mm, with 73 components from 51 distinct parts.
Its main chip is the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family. Other key parts include the TC4424EPA, IXDN602SIA, MPXH6115A6T1, TS2940CP50 and MPXH6400AC6U. By type, the board carries 21 capacitors, 19 resistors, 7 ICs, 7 transistors, 6 diodes and 5 jumpers.
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.
