Hardware specifications for the programmable variant
If the module has the programmable secondary processor, add the following table values to the
specifications listed. For example, if the secondary processor is running at 20 MHz and the primary
processor is in receive mode then the new current value will be Itotal = Ir2 + Irx = 14 mA + 9 mA = 23 mA,
where Ir2 is the runtime current of the secondary processor and is the receive current of the
primary.
Optional secondary processor
