Controller

Custom circuit board:

The Controller PCB is responsible for charging a LiCD battery, as well as powering the screen board, which is an independent unit. The board contains through holes for the NRF24L01+ module, along with 4 LMS-5161 common anode 7 segment displays that are controlled by 4 74HC595 8-bit shift registers, all of which are controlled by an arduino nano every and powered by the LiCD battery.

Questions

How big is the Controller PCB?

It measures 144 × 74 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Controller use?

82 parts, built around the 74HC595 and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Controller KiCad files?

From the Jer8Jun/rc-rover repository on GitHub, at the commit this page was made from: the board is Controller/PCB/Controller.kicad_pcb and its schematic Controller/PCB/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask Jer8Jun before reusing the design.
