Connecting the AIR A2530 module to an external microcontroller

Designing a circuit to connect the AIR A2530 modules to an external microcontroller is a straight forward process. Here is a list of the minimal set of connections required. Please also refer to the [A2530x24x-LPZ BoosterPack Users Manual] for an example schematic and bill of materials as further guidance.

The following recommendations are based on the following assumptions:


 * Module is running Anaren's AIR-ZNP factory default software (based on TI Z-Stack and ZNP software).
 * SPI communications between the A2530 and the microcontroller.
 * No external 32 KHz crystal attached.
 * It is desired to be able to populate the board with either an A2530E24x or an A2530R24x module.
 * A 10-pin 2x5 header (Samtec SHF-105-01-L-D-TH or equivalent) will also be placed on the board. This header will be used to attach to a TI CC-Debugger for programming and updating the A2530 module firmware.  This header will be referred to as the programming header in the table below.  See J4 on the BoosterPack schematic as an example.
 * The four GPIOx pins are completely optional, and can be left unconnected if not used.
