About the NO2C PCB

NO2C 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 78 components from 55 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, 21 resistors, 8 ICs, 7 transistors, 6 jumpers and 6 diodes.

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.

The KiCad project lives in the turboedge/SpeedyBoards repository on GitHub; these links point at the commit this page was built from.

NO2C: common questions

What microcontroller does the NO2C use?

The NO2C is built around the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family.

How big is the NO2C PCB?

The NO2C measures 99.4 × 53.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NO2C?

78 components, from 55 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the NO2C design files?

From the turboedge/SpeedyBoards repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the NO2C design in my own project?

Yes, under the terms of its GPL-2.0 license, which turboedge chose for the repository.

Can I test firmware for the NO2C without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
