The third hardware generation, currently being designed. The proposed system architecture is shown below; the boards under PCBs/ are the work toward it. The current working vehicle is still gen2/.
- MicroBreakout/ — the main breakout board for gen 3, the successor to the gen 2 MLU breakout. References the shared parts library in ../../importedparts. - BatteryBoards/ — the gen 3 power-management / battery boards, the follow-on to the gen 2 PowerManagement boards (which had heat problems). Two design variants: - PowerManagementV3diode/ — the diode-based design; this is the lead design. -…
