Receptacle connector 0.5mm pitch
DF12-20DS-0.5V
from
HIROSE
- Compatible with Header HIROSE Series DF12
(ex : DF12(5.0)-20DP-0.5V(86)
DF12B(5.0)-20DP-0.5V(86)
DF12D(5.0)-20DP-0.5V(81)
DF12E(5.0)-20DP-0.5V(81) )
- Using this connector requires a height of 5mm between WLn-
LINK-OEM and your motherboard (see chapter
"MOUNTING OF THE
DEVICE"
for more information)
- This connector is not needed for common use of the WLn-LINK-
OEM. It only provides some additional functions.
I²C and UART1 should be only used with ACKSYS authorization.
Their incorrect use could irremediably corrupt the product and
void all pertaining guaranty.
