README
README.mdCustom Bluetooth Devboard
This is a cutom bluetooth devboard made by me for IoT and short range communication and automation.
This board uses a nRF 52840 QIAA-F-R7 along with a RP2040 for processing, wired together with SPI.
It also uses 2 crystals 12MHz and 32 MHz for thr Rp 2040 and the nRF 52840 respectively.
A TLV75533PDBV (LDO) as my Voltage regulator.
2 USB-C receptacles for programming both chips with firmware.
SMD resistors.
SMD capacitors.

Questions
How big is the Bluetooth DevBoard PCB?
It measures 85.3 × 54.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bluetooth DevBoard use?
63 parts, built around the RP2040, W25Q128JVSIQ, TLV75533PDBV and FA-128. 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 Bluetooth DevBoard KiCad files?
From the GodOfStrategy/Bluetooth-Devborad repository on GitHub, at the commit this page was made from: the board is Project Files/Bluetooth_DevBoard.kicad_pcb and its schematic Project Files/Bluetooth_DevBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bluetooth DevBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
