22-pin-definition
221-default-and-multiplexing-pin-definition
There are 35 pins in LDI12B000A module, refer to below chart 7 & chart 8 for pin definition. “Default Pin Definition” in Chart 9 means the recommended pin function definition. Usually, customers need to choose target pins according to the pin definition in this column of Chart 8.
In some special projects, if "default pin definition" can’t meet the needs of products, then "Multiplexing Pin Definition" function can be chosen. However, when choosing this multiplexing function, need to consider whether other modules that have the same package, also have the same multiplexing function.

4--application-notes
41-suggestion-on-backplane-design
411-antenna-matching-network-reserved
A 2.4GHz antenna is needed in the driver backplane and the antenna is designed according to different product structures and driving schemes, to ensure the best wireless communication performance of each kind of product. Here are the suggestions for antenna design as below:
Chart 16.Module Application Diagram（Unit: mm）
\1. An avoidance area is recommended to be reserved for antenna design, and it should be as close as possible to the edge of the backplane； See more details in chapter 4.1.2；
\2. It is necessary to reserve a ‘π’ matching network for antenna impedance matching.
\3. The path of ‘π’ network components must be designed to be 50Ω impedance.
412-antenna-design-recommendation
Chart 17.Recommended antenna design
The 2.4 GHz antenna which used cooperatively with the LDI12B000A module is to be designed according to the whole product environment. Different antenna performance would cause wireless communication distance difference.
Below are the antenna parameters typical value recommended.
| Parameter | Value |
|---|---|
| Frequency Range | 2.4 ~ 2.5GHz |
| Impedance | 50 Ohm |
| VSWR | 2.0(Max.) |
| Return Loss | -10 dB (Max.) |
| Antenna Gain | 0~2dBi peak gain |
| Antenna Type | Integrated PCB antenna |
| Efficiency | >30% |
Chart 18.Recommended Antenna Parameters
In addition, there are some guidelines that need to be taken into consideration.
\1. Make sure that antenna is not in contact with any kind of metal.
\2. The antenna should be places as far away from any metal structures as possible. At least 10 mm away is needed.
\3. Antenna types having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this module. Under FCC/CE/ISED regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by FCC/CE/ISED. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropic radiated power (e.i.r.p.) is not more than that necessary for successful communication.
