Gerber file
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
The use of our Gerber files is provided under a modified Creative Commons license. Creative Commons offers authors, scientists, educators and other creatives the freedom to handle their copyright in a more free way without losing their ownership.
Extra info / Update
• PCB form factor similar to Arduino Pro Mini
• Small size: 2.5 x 5.5 cm
• ATmega328 processor with Arduino bootloader with direct serial connection to eRIC module
• 8-MHz operation
• On-board 3.3-V regulator providing power to eRIC module and ATmega328 device
• Header for FTDI friend connector, to allow ATmega328 programming from Arduino IDE and also to provide serial communication interface
• Quickly deployable as a battery-powered low-power programmable RF node
• Total current consumption in low power mode <100 µA
• Open source, open hardware design
Components
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
