- change the DC/DC, we suggest "THD 12-2410WI" from TRACO.
- in order to bypass 802.3af negotiation you will need to connect DC4.4 to DC4.5. It is easier to connect trace to via as you can see on the photo.
Traco THD 12-2410WI documentation show that efficiency is optimal with input voltage: 16-17v.
Using Elphel NC353L-10369-HDD camera on 12v battery is not recommended. 12v is a marginal application for this DC/DC and may damage your HDD with frequent reboot. some 16-24v battery is preferable.
