README
README.mdBEAMO
BEAMO is a simple, low-cost RF remote controller for robots and toys based on the common nRF24L01+ and its more ubiquitous counterfeits. 32 may be operated in the same space by selecting different channels using the configuration DIP switch.
The board itself is a simple 2-layer PCB designed to be operated without an enclosure. There are mounting holes to allow attachment of a custom grip.
Example receiver code has been tested on an Arduino Uno using a matching nRF24L01+ module.
Firmware
The remote is intended for real-time control of a vehicle. As such, it sends button updates at a minimum of every 100ms. When the data changes, it may send as frequently as every 10ms.
The remote firmware was built in PlatformIO (for Raspberry Pi Pico) but should also be portable to the Arduino IDE. The receiver example for Arduino Uno is built in the Arduino IDE.

Questions
How big is the Rf controller hw PCB?
It measures 127 × 69.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rf controller hw use?
16 parts, built around the NRF24L01 and RP2040-ZERO. 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 Rf controller hw KiCad files?
From the bnahill/rf-controller repository on GitHub, at the commit this page was made from: the board is rf_controller_hw/rf_controller_hw.kicad_pcb and its schematic rf_controller_hw/rf_controller_hw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rf controller hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask bnahill before reusing the design.
