Reference Manual ATOM one 4K mini
This connector has a 3,3V Uart interface to control the camera.
The interface behaves like the RS485, but must be use for peer to peer conections. No
adressing like on RS485 is required.
The I2C interface is reserved for future use like lense control or other extentions.

2.2 Over-Temperature Protection
The ATOM one mini has a very compact design which does not allow for active cooling.
Thus the device will get hot under operation. To protect the device the camera will go into
a safe operational mode when the internal CPU temperature reaches 70°C, this will be
indicated by toggling the status LED between orange and red.
The camera will stay in this state until the CPU temperature drops below 50°C, it will then
reboot automatically and resume operation. Alternatively you can power-cycle the device,
but keep in mind that as long as you did not improve the cooling the camera will probably
reach the temperature limit again after a short time.
To keep track of the current cpu temperature use the
temp
command. The camera also
logs the maximum CPU temperature which can be read out using the
max_temp
command. You can reset the logged maximum temperature using the
max_temp_reset
command.
Every time the camera reaches the 80°C temperature limit, an over temperature counter
will be incremented. You can read the counter value by using the
over_temp_count
command. This counter value is persistent and can not be reset by the user.
