Bluetooth Roadbook Controller for iOS/Android

@markoa7

Hi there, I’ve reviewed the Rally-Media-V3 brief and I can deliver a compact BLE roadbook controller with robust noise immunity for off-road use. I’ll design a 4-layer PCB (0603/0402 parts) optimized for JLCPCB, with a buck regulator to 3.3V from 12V, TVS protection, EMI filtering, and a reliable nRF52840 core handling HID multimedia control and 5 digital inputs. Path A or B can be unified on a single schematic with careful RF layout and a clear keep-out for potting. Firmware will run a clean bootloader path, auto-connect, and HID reports over BLE. What is your target runtime expectation and the preferred path (Integrated nRF52840 PCB or Shield for Seeed XIAO) for validation milestones? Best regards, Marko Aleksic
