BotBricks: predictable timing for Pi 5 robots
BotBricks is an in-development FPGA HAT for Raspberry Pi 5 robots, designed to handle motion I/O, sensor timestamps, and safety stops alongside ROS 2.

- Worth noticing
- The timing diagram is explicitly labeled an illustration, not measured data; the connector list is still a changing design target.
Field notes
The proposed architecture assigns timing-sensitive I/O to an FPGA while leaving the robot’s policy and ROS 2 stack on the Pi. Its comparison table distinguishes that focused role from built-in RP1 PIO and more general-purpose Kria kits, and the page says existing per-joint motor drives remain part of the setup. The timing graphic is labeled as illustrative rather than measured, and the connector list is still subject to change.
