4.2.2 WiFi Modules

As stated in paragraph 3.3.6, on the SBC-A62-J there is an internal USB port, on a 6- or 7-pin female header, which has been purposely

designed for the connection of USB WiFi modules, although it can be used for any USB 2.0 compliant device.

SECO can offer two different WiFi modules on USB pin header. Both of them are IEEE 802.11 b/g/n compliant, FCC Part 15 and CE

compliant, 150Mbps maximum data rate, security support for 64/128 bit WEP, WPA, WPA2, TKIP, AES.

The first module has an integrated PCB antenna, and is based on Ralink RT5370 chipset. It has a 7-pin USB interface

to use modules different from those provided by SECO, and whose drivers are already included in SECO's provided BSPs.

Please contact SECO for ordering p/n.

SBC-A62-J

This kit is necessary to connect Debug programming port, available on connector J31, to a standard PC serial port through a

null-modem serial cable..

The kit is made of:



TTL-to-RS232 serial port adapter



Connection cable between SBC-A62-J board and TTL-to-RS-232 adapter

To use this kit, connect the cable to connector J31 on SBC-A62-J board and to connector CN3 on the TTL-to-RS232 adapter

module. The debug serial port will now be available, at RS-232 level, on the module's connector CN1, which is a standard DB-

The second module, instead, is based on Ralink RT3070 Chipset, and it is supplied with an external 50Ω 2.4GHZ

antenna. This module has a 6-pin USB interface.

Please be aware that the two modules have an USB interface with a different number of pins. Each module

therefore has to be paired with a board with the corresponding number of pins. Please keep in mind the

modules desired when ordering a WiFi module and/or a SBC-A62-J board.

Obviously, these are not the only WiFi modules that can work combined with the SBC-A62-J board. The customer

can choose any USB WiFi module. However, please remember that SECO cannot support customers if they choose
