0.1" proto-board for DIY shields SVG headers on all signals for 3-wire sensor/actuator modules ICSP programmer mode allows you to use the Omega-328 SB as a avrisp compatible programmer SI Labs CP2103 USB bridge for high performance USB 2.0 capability ... -
Page 4: Getting Started
Getting Started 1. Installing the Driver The Omega-328 SB uses a Silicon Labs CP2103 USB bridge for communication and downloading sketches from the Arduino IDE. This requires that a driver be installed before the Omega-328 SB is attached to the host computer and powered up. -
Page 5: Attaching The Power
With the USB cable connecting the Omega-328 SB to the host, and the MCU inserted, apply the power by connecting the chosen power source. -
Page 6: Usage
Windows when the Omega-328 SB was attached to the host and powered up. If you purchased your Omega-328 SB with an Atmega328 microcontroller supplied from an authorized OMS dealer, it will have an Arduino Duemilanove bootloader pre-loaded. -

6 pin female header on the shield base of the Omega-328 SB. Be careful to make sure all other pins are aligned properly before pushing the shield into the shield base. The pin spacing of the standard Arduino shield base does not follow standard 0.1”... -
Page 8: Power Usage Considerations
Power Usage Considerations General Considerations With a Vin of 9V, the Omega-328 SB power supply is capable of supplying up to 500mA in free air and up to 1 Amp with adequate additional heat sinking. 1 Amp of current should easily be enough to meet needs of any number of sensors, as these generally have small power requirements. -
Page 9: Alternate Connectivity
Remember, if you are using a breadboard circuit as a part of your prototype project keep in mind that the ground of the Omega-328 SB will need to be properly connected to the off-board circuit’s ground to ensure a good voltage reference and a suitable return path for power and signals. -
Page 10: Accessing The Mcu I/O
Accessing the MCU I/O When inserted into the Omega-328 SB all the I/O pins of the MCU map to the SVG headers. D8 though D13 as well as AREF are brought to the header to the upper right of the MCU socket (H1), D0 through D7 are brought to the header to the lower right (H2) and A0 through A5 are brought to the header to the left (H3). -
Page 11: Shield Base Pin-Out
Shield Base Pin-out The Omega-328 SB shield base in comprised of headers H4 – H7 and follows precisely the standard Arduino UNO pin-out. Refer to the SVG Header Pin Mapping table above for functions and MCU Mapping. An additional header at H5 on a standard 0.1”... -
