# OpenRCore
|
|
|
|
|
|
|
|
|
|
OpenRCore ("Open Robot Core") is an open source project intended to provide a
|
|
|
|
|
similar development experience as FIRST Tech Challenge's [FtcRobotController](https://github.com/FIRST-Tech-Challenge/FtcRobotController)
|
|
|
|
|
but supporting more affordable hardware.
|
|
|
|
|
|
|
|
|
|
## Hardware Overview
|
|

|
|
|
OpenRCore targets the nRF52840 devkit, rather than the REV control hub. This
|
|
|
|
|
hardware was chosen for a few reasons:
|
2025-01-01 22:45:50 -06:00
|
|
|
|
|
|
|
|
- Cost & Availability: The nRF52 devkit is available from multiple vendors, and
|
2025-01-02 18:08:50 -06:00
|
|
|
runs for less than $50 USD.
|
2025-01-01 22:45:50 -06:00
|
|
|
- Integrated Bluetooth: The devkit comes with built-in Bluetooth, which is used
|
|
|
|
|
for connecting via a server control application.
|
|
|
|
|
- Zephyr: The devkit is intended to be used with Zephyr (what this project is
|
|
|
|
|
using), and is a great introduction into embedded development.
|
|
|
|
|
- Arduino Shield Compatible: The devkit has the same pin-out as an Arduino, so
|
|
|
|
|
the project can be extended to support a variety of shield peripherals.
