1.2.4 Connection to the Accessory Sensor Module:

There are total four connectors can be connected with AEO Apache sensor modules.

These four ports are having the same function. Any of them can be connected with any of

the AEO Apache sensor modules. The OSD main board will detect the type of the module

automatically. Currently, only the temperature sensor module shown in Figure 1.9 is

supplied with this kit. The side with an 8-pin IC chip of the temperature sensor module

must be attached to the component surface that the

temperature needs to be sensed. There are few other modules

are under development and will be released in the early future,

such as the compass module, ultra-sonic altitude module, air-

speedometer module and pressure altitude module. The black/

red/ green/ yellow pins connect to the ground/ +5V/ data1/

data2 of the sensor modules, which are the black/ red/ green/

yellow wire of these sensor modules receptively. Please note

that the ground/ black pin is on the most left of this port.

1.2.5 Connection to the OSD Power Module:

The OSD power module is one of the most essential component of the AEO Apache OSD

system. It supplies the power to the all OSD components, and in the same time sense the

real-time current and voltage of the power battery. Normally, the motor power should be

supplied via this power module to sense the real-time power battery status. The power

module and the main board are connected with the

supplied 4-pin connector cable as shown in Figure 1.10.

The pin conﬁgurations are shown in the Figure 1.2 that the

black/ red pin are the ground/ +5V power supply, the white/

yellow pins are for the current and voltage sensing. The

battery pack should be connected to the connector marked

with “IN” of the power module, and the electrical speed

controller should be connected to the connector marked

with “OUT” of the power module.

1.3 Port Group B:

There are 5 connectors in the port group B, which are located on the right of the OSD main

board. The pin conﬁgurations are shown as per Figure 1.11. From the top to the button are

as following:
