README
README.mdBleBomB
BleBomB is a compact embedded device designed to generate 2.4 GHz noise using an NRF24 module and the MM32G0001A1T MCU.
The device continuously transmits randomized packets in the 2.4 GHz band, which can create heavy interference for nearby wireless communications operating on the same frequency range.
Overview
BleBomB is a fully embedded hardware project developed by RDH Roboticss. This repository contains all the necessary hardware design files required to reproduce the device.
The system is built around a low-power microcontroller and a 2.4 GHz RF transceiver to produce rapid wireless transmissions.

Questions
How big is the BLEBOMB PCB?
It measures 29.6 × 15.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BLEBOMB use?
24 parts, built around the MM32G0001A1TC, ME6211C33M5G-N, TP4057 and WS2812B. 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 BLEBOMB KiCad files?
From the rdhrobotics/BleBomB-Hardware repository on GitHub, at the commit this page was made from: the board is BLEBOMB.kicad_pcb and its schematic BLEBOMB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLEBOMB design in my own project?
Its repository states no licence, so its author keeps all rights: ask rdhrobotics before reusing the design.
