 # TODOs
+## Custom electronics
+### Power management board
+* Input voltage: 5 - 20/30 V DC (solar or USB-C)
+* Output voltage: 3.3 V (MCU), 5 V (Pi)
+* Battery charger (LiFePO4, Li-Ion, ...?)
+* Maybe: Battery holder (18650?)
+* Voltage monitoring for input and battery, current monitoring probably not necessary
+* Microcontroller: ESP32 (S3 for camera?)
+* Mircocontroller programmable via USB-C(?)
+* Exposed external Pins for interacting with MCU (e.g. trigger wake up, additional sensors, etc.)
+* RTC -> Use external or internal one? -> Test accuracy
+* Protection circuitry (reverse polarity, overvoltage, overcurrent, etc.)
+* Button for manual wake up / activity LED
+* Max. power draw for Pi + camera + 4G module: maybe 5 W / 1 A (potentially more for compute module), typical ~2 W / 0.4 A
+* Max input power ?
+* Connection to Pi (I2C over 40-pin header?)
+
+* Software: watchdog, brownout detection, ...
+

+* https://www.uugear.com/product/witty-pi-4-l3v7/
+
+### Connectivyit / camera
+* Add 4G-module, potentially with GPS
+-> Preferably with m.2 connector for replacability/upgradeability (see e.g. https://www.lilygo.cc/products/t-simcam, https://www.lilygo.cc/products/a-t-pcie?variant=42335922094261)
+
+* Add camera interface for esp32
+* Maybe use compute module and add ethernet
+
+
+
 ## V2.0
 - [ ] Add one time actions/change detection in settings
 - [ ] Automatic time drift detection (maybe with GPS, dependent on startup reason)
