We are building a sensing device that uses a RAK3172 and may be used in a Class 1 Div 1 hazardous environment. This requires the device be certified intrinsically safe. This also requires certain information. What is the sum total of all the capacitors capacitance internal to the RAK3172? Do you have a value for the thermal resistance to ambient for the unit in C/W? (Degrees C rise per Watt) Is the STM32WLE5CCU6 the only device except some bypass capacitors to connect to the positive power rail? I would very much appreciate a response to these questions.
