Precautions for use:

The module interface adopts half-circle pad method, all GND pins should be connected reliably with the logic ground of system circuit.

 The antenna part should be far away from the system ground.

There is no integrated hardware SPI interface microcontroller can also control this module, with ordinary I / O port simulation SPI timing read and write operations can be, SPI rate should not exceed 10MHZ.

If the module is powered by 3.3V, it can be directly connected to the IO port of A7108 module. If connected with 5V power supply microcontroller, generally recommended series 1-4.7K resistor, otherwise it is easy to burn the chip.

GIO1 and GIO2 are general-purpose digital I/Os that can be configured to generate the required signals according to the application. 7.

In multi-channel applications, the channel spacing is 1MHZ, if less than 1MHZ, easy to generate co-channel interference.
