Components
Controller
The board uses a RP2350 Stamp XL from solder party that, other than the micro-controller, mounts:
- 16 Mb of external FLASH
- 500 mA 3.3V LDO
- Footprints for external SWD and UART JST connectors
The Stamp has been chosen for the ease of mounting and for a lack of a commercially available RP2350 board / chip at the time of design. The main downside is the dimensions of the castellated board, which define the board layout.
Power Supply
The Ulysses flight computer uses an MPM3610 switching regulator with a maximum load of 1.2 A. This converts the +BATT voltage down to +5V. The voltage is then lowered by the Stamp internal LDO down to +3.3V.
