Custom RTL8735BDM PCB Design
AUD 30–250
About the project
I’m migrating my current AMB82-mini daughter-board solution to a single, production-ready PCB built around Realtek’s RTL8735BDM module. You’ll have the original AMB82-mini schematic and layout in PADS binary as a starting point; the goal is to recreate and extend that design in Altium Designer. Essential upgrades • Integrate a DS3231 RTC • Add a LiFePO₄-compatible battery gauge with coulomb counting • Provide a full-size SD-card slot • Break out USB and SPI/I²C headers for easy access during development and in-field updates What I expect as a turnkey hand-off • Altium schematic and multilayer PCB layout • Optimised stack-up, impedance-controlled traces where needed • Manufacturing package: Gerbers, drill files, pick-and-place, 3D step, fabrication & assembly drawings • Verified BOM with second-source components and current availability • Brief design report covering key decisions and test points Acceptance criteria • All added features operate from the same power domain without disrupting Wi-Fi/BT performance of the RTL8735BDM • Board passes basic ERC/DRC in Altium and conforms to standard PCB house specs (6/8-layer, 4 mil/4 mil minimum) • USB, SPI and I²C lines show clean signal integrity in the layout review • Deliverables import directly into Altium without missing libraries I’m looking for someone with a strong embedded background, proven multilayer experience and a track record of 5-star projects who can steer this design all the way to a build-ready status. If that’s you, let’s get started.
