(1) The Voltage range of the wireless modules VCC is between 1.8V-3.6V. But it is not allowed to be beyond the range, because the module will be burnt if the voltage is more than 3.6V .And the recommended voltage is about 3.3V.
(2) Except VCC and GND, the rest of pins can be connected to ordinary 51 MCU IO port directly without level conversion. And it is certainly more suitable for 3V MCU.
(3) The MCU without SPI can also control the module. It simulates SPI by using ordinary MCU IO port. But either the ordinary MCU IO port or serial port is available to take place of the real serial port of MCU. Besides, the module can be connected to the mother plate logically according to the tips about interfaces.
(4) Stamp hole interface. If other packaging interfaces or other forms of interfaces are preferred, they can be customized.
(5) Any MCU can achieve the data transceiver control of wireless module, and in accordance with the programs we provide. And you can transplant the type MCU according to your preference
(6) Channel spacing Specifications: actually, if you want to launch two modules simultaneously launched without mutual interference, the channel spacing between the two channels should be at least 1MHZ. This should be noticed to avoid the co-channel interference.
(7) The actual user may use their familiar MCU as the master control chip, but there are four notes should be noticed:
A: Make sure the IO input and output, and must be set to IO;
B: Remember to finish the register setup, relative to the IO ,especially that the IO with the external interrupt and AD function ,and the relevant registers must be set
C: when you debug it, please write configuration word initially, and then control the data transceiver
D: Pay attention to the switching period of operation mode
