**GENERAL TODOS**

  

- [ ] Proper Power connector to connect with PDB

- [ ] Our own gps module

- [ ] Working heat-sink solution: --> place corals further apart from each other.

- [ ] Make the board smaller! --> Weight saving, less expensive

- [ ] Use both sides for components.

- [ ] Put more LED's:

- [ ] Make more pinouts if V0.2 is still a debug board.

**Ideas:**

Do we want to integrate more sensors onto the board? Temperature, pressure, gyro? #question

How do we measure the position of the flaps/payload bay? #question

Do we need more storage? Implement flash storage or sd-card? #question

Buy sara board from [sparkfun](https://www.sparkfun.com/products/14997)?

**To Decide before start:**

- [ ] USB-C yes or no?

- [ ] MIPI yes or no?

- [x] Open drain pins: use own transistor or device tree approach? --> Open drain also for PWR_ON

- [ ] DEBUG board: yes or no?

- [ ] Stress test antenna sara.

**Precise TODO's:**

- [ ] Remap SARA Rx/Tx

- [ ] Decide scope of board: still debugging?

- [ ] Rewire orange coral status led: with datasheet decide current limiting resistor to have full power at steady on. --> allows to regulate dimness with pwm.

- [ ] Use large size resistor for important settings: e.g. voltage regulators

- [ ] Make single pin of gnd to attach oscilloscope crocodile clamp

- [ ] Find Power connector to connect to PDB.

- [ ] Remove 0-Ohm resistors where they are not needed anymore, but provide testpoints!

- [ ] Don't use Testpoints: Use holes like jtag: you can later on add pins if needed.

- [ ] Add LED to id-pin of cc-control of usb-c (it is a open drain pin) --> when pulled to gnd it should activate a transistor that connects the led to gnd.

- [ ] Gpio link to do hard reset between corals.

- [ ] Flight controller connectors:

- [ ] 2x UART

- [ ] 2x GND Power

- [ ] 2x 5V Power

- [ ] ?x GNSS connection

- [ ] ?x GND between lines for shielding

- [ ] General Connectors

- [ ] 1x GND, 5V for RC (asym-conn)

- [ ] 2x GND, 5V for fans (asym-conn)

- [ ] 5x GND, 5V DNP conn for eventualities

- [ ] same with 3.3v and 1.8V
