<li>By default, no simple way to get online (no built in wifi/BLE/ethernet). Ethernet can be easily added - wifi still work in progress - see <em>Networking</em> below)</li>
<li>Annoying SDK for building firmware images</li>
<li>No simple way to compile drivers (no available Linux headers - if anyone manages to compile the headers, please let me know)</li>
<li>USB seems very power limited - highest observed current is low - just 0.08a at 5v (0.4w). It seems that if power draw exceeds this limit, the device will bootloop or hard crash</li>
<li>If the power draw of a USB peripheral exceeds what the Luckfox is able to provide, it will reboot, bootloop or even hard crash. This appears to be avoidable by simply using a sufficient power supply, though this requires more testing</li>

<li>Prevent hanging on boot when no network ("[ ***] A start job is running for Raise network interfaces (2min 10s / 5min 6s"). Also, on reboot</li>
<li>Test power consumption with LoRa radio attached / figure out what size solar panel will be required</li>
<li>Work out i2c sharing between OS and Meshtasticd - allow mesh to access sensors while RTC is accessible to OS</li>
