4.2 Accessories
SECO can offer various accessories in completion of SBC-984 functionalities
4.2.1 RS-232 programming kit ASK-825REVB
The connecting cable will also carry out the two I2C signals available on connector J7. On the adapter module, these signals cannot be used, this means that the
user can disconnect the two wires from the 10-pin connector and use them to connect an I2C touch Screen controller. Yellow Wire: I2C3_SCL signal, White wire:
I2C3_SDA signal.
4.2.2 WiFi Modules
As stated in paragraph 3.3.4, on the SBC-984 there is an internal USB port, on a 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.
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.

This kit is necessary to connect Debug programming port, available on connector J7, to a standard PC serial port.
The kit is made of:
TTL-to-RS232 serial port adapter
Connection cable between SBC-984 board and TTL-to-RS-232 adapter
To use this kit, connect the cable to connector J7 on SBC-984 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-
9 male connector.
The second module, instead, is based on Ralink RT3070 Chipset, and it is supplied with an external 50Ω 2.4GHZ
antenna.
Please be aware that the module with external antenna has a 6-pin USB interface, so, when mounting it on
7-pin connector CN4, it is necessary to insert it in pins 2-7, leaving pin 1 free.
Obviously, these are not the only WiFi modules that can work combined with the SBC-984 board. The customer can
choose any USB WiFi module. However, please remember that SECO cannot support customers if they choose to
