Omega2 Arduino Dock R2
£16.54 ex VAT
The Arduino Dock R2 is a supercharged version of an Arduino Uno R3 board. These two boards share the same microcontroller, the ATmel ATmega328P microcontroller (MCU), and have identical pin layouts. This allows you to use any Arduino shields that you've used with the Arduino Uno R3 with the Arduino Dock and the Omega.
The Omega can program the microcontroller while connected to the board. This means you can wirelessly connect to the Omega, and then program the MCU for a wireless Arduino experience!
The Arduino Dock includes an In-Circuit Serial Programming (ICSP) header to break out the SPI pins which can be used to program the Arduino Dock's microcontroller with an external programmer. Additionally, there is a USB-host port that is connected to the Omega which can be used for any sort of USB type application.
The Expansion Header is a convenient tool that gives you easy access to the Omega's GPIOs, and allows you to connect Onion Expansions directly. The Expansion Header is labelled to show you what GPIO is connected to each header. The ATmega headers are a breakout of the ATmega's pins. They are arranged and spaced in the exact same way as an Arduino Uno R3, so all your Arduino Shields are compatible. These pins are also labelled for your convenience.
Note: There is no USB-to-Serial Chip on this Dock. This means that you will not be able to connect to the Omega serially over the Micro-USB port. You can still connect to your Omega's terminal with SSH.
- Micro-USB port - port is used to supply power to the Arduino Dock
- DC Barrel Jack - used to provide power to the Omega using a DC power adapter.
- Reset button - Reboot and factory restore
- Micro-Controller Reset Button - used to reset the ATmega chip
- Omega USB Port - USB 2.0, and is a type A connector
- Omega to ATmega MCU Connections - outfitted with a 3.3V to 5V Logic Level converter
- UART Connection - used to provide two-way communication between the Omega and the ATmega MCU
- I2C - provides I2C connectivity between the Omega and the ATmega
- SPI and Reset Connection - four SPI connections are used to upload the ATmega with sketches
