The 3 mm wide slots covering the plate support many configurations of sensors and other robot components. The slot size and spacing is compatible with the many [Tamiya mechanical sets](https://core-electronics.com.au/category/61/tamiya-products) that have 3 mm holes spaced 5 mm apart. Included with the plate are four tapping screws for mounting the plate to the Rover 5 tracked chassis. These plates were originally designed for Pololu's now-discontinued [RP5 chassis](https://core-electronics.com.au/catalog/product/view/sku/POLOLU-1059), but they are also compatible with the Dagu Rover 5. However, Pololu have noticed a misalignment between the mounting holes on the expansion plate and the Rover 5, so you might only be able to secure the plate with two screws on opposing corners. These plates can also be used on their own as chassis for custom-built robots or even just as general-purpose mounting plates to keep project electronics neat and tidy: | \| [![](https://core-electronics.com.au/attachments/localcontent/0J3419_24822946b5f.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3419_245766c6298.jpg) \| \|---\| \| Dagu Rover 5 chassis with Orangutan SVP robot controller and additional electronics mounted to an RP5/Rover 5 expansion plate (narrow). \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J5872_255950ca67a.jpg)](https://core-electronics.com.au/attachments/localcontent/0J5872_5904832bd64.jpg) \| \|---\|---\| \| Pololu RP5/Rover 5 Expansion Plate (narrow version) serving as a general-purpose mounting plate. \| | |---| | [![](https://core-electronics.com.au/attachments/localcontent/0J1589_27408e24de2.jpg)](https://core-electronics.com.au/attachments/localcontent/0J1589_34558ec92fb.jpg) | |---| | Two RP5/Rover 5 expansion plates with an Orangutan SV-328 and an Arduino Duemilanove. | | [![](https://core-electronics.com.au/attachments/localcontent/0J1588_2828307b643.jpg)](https://core-electronics.com.au/attachments/localcontent/0J1588_385465da4f2.jpg) | |---| | Pololu RP5/Rover 5 wide expansion plate with a TReX Jr. and an RC receiver. | | [![](https://core-electronics.com.au/attachments/localcontent/0J1590_20608b3a931.jpg)](https://core-electronics.com.au/attachments/localcontent/0J1590_26615a7da03.jpg) | |---| | A narrow RP5/Rover 5 expansion plate with an Orangutan SV-328 and a Sharp digital distance sensor. | The Pololu RP5/Rover 5 expansion plate comes in both narrow and wide versions.
