C&DH Board Design Requirements: The Command and Data Handling (C&DH) Board is the link between our satellite and the rest of the world. The C&DH board will also handle the broad level scheduling of satellite activities.
Key Requirements:
- Facilitate Radio Receive and Transmit
- Collect Satellite State of Health Data
- Process Satellite Data into Packets for Transmission
- Schedule High Level Satellite Activities
Would be nice:
- Facilitate a live engineering data link with other processors onboard the satellite
- EPS Board Design Requirements:
Non-Optional:
- Overcharge Protection
- Overdischarge Protection
- Solar Charging Circuit
- 3.3V Regulator
- 5V Regulator
- Inhibit Scheme
- Battery Monitor
Very Preferred:
- Direct RP2040 Control On-Board
- Battery Fuel Gauge
- Power Path Circuit
- Battery Thermal Management
Would be Nice:
- Circuit Breaker System
- Resettable Fuses
The EPS board will be a hybrid of the PyCubed and OreSat architectures.

Questions
How big is the SpresensePart2 PCB?
It measures 89.6 × 59.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SpresensePart2 use?
30 parts, built around the 74LVC244APW. 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 SpresensePart2 KiCad files?
From the pleiades-cluster/yearling-electronics repository on GitHub, at the commit this page was made from: the board is Saddle Board/SpresensePart2.kicad_pcb and its schematic Saddle Board/SpresensePart2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SpresensePart2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pleiades-cluster before reusing the design.
