REGISTER FORUM / OMEGA DOCKS / ARDUINO DOCK R2 FOR ONION OMEGA Arduino Dock R2 for Onion Omega DEV-14438 DESCRIPTION FEATURES DOCUMENTS The Arduino Dock R2 allows you to supercharge your projects by combining the familiar Arduino platform with the power and connectivity of the Omega2. Each dock features the ATmega328P microcontroller as a coprocessor to act in tandem with the Omega, and exposes the GPIO pins of both the Omega and the microcontroller. If you are looking for a way to incorporate both Arduino and Onion Omega into your next project, there isn't a finer choice than the Arduino Dock R2! The Omega facilitates programming the microcontroller wirelessly using the Arduino IDE, while it and the ATmega328P can communicate through a Serial UART connection or using the I2C bus protocol. The microcontroller pins are all accessible and arranged in the same way as the Arduino Uno, giving you the ability to quickly port over Arduino projects and reuse any existing Arduino Shields. The Onion Omega boards we carry are separated into three different categories: Mainboard, Dock and Expansion Board. This board falls into the Dock category, meaning you can plug an Onion Omega directly into the board. The Arduino Dock R2 is also compatible with Omega Expansion Boards and Arduino Shields. images are CC BY 2.0 Tags SHARE ARDUINO DOCK EXPANSION OMEGA2 OMEGA2+ ONION ONION OMEGA SHIELD Arduino Dock R2 for Onion Omega Product Help and Resources SKILLS NEEDED VIDEOS Product Showcase: Onion Omega2 PUBLISHED ON SEPTEMBER 21, 2017 COMMENTS REVIEWS 2 0 Customer Comments Log in or register to post comments. SebCestBien / about 5 months ago / 1 It's possible to fit Arduino Shield and Onion Hat at same time ? it'seems that is not enougth space between connectors... xtopher / about 5 months ago / 1 I've tried a few different shields with the Expansion Boards and I haven't had any luck attaching both at the same time. So in answer to your question: no, it looks like you can't fit both of them on at the same time. START SOMETHING.
