+**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
