2.11 Daughterboard
extension connectors CN10 and CN11
Two 70-pin male headers (CON1 and CON3) can be used to connect the daughterboard or
standard wrapping boards to the STEVAL-IHM022V1 demonstration board. A total of 112
GP I/Os are available. The space between the two connectors and positions of the power,
GND and RESET pins are defined as a standard which allows development of common
daughterboards for several demonstrations boards. The standard space between CON1 pin
1 and CON3 pin 1 is 2700 mils (68.58 mm). This standard is implemented on the majority of
ST demonstration boards equipped with MCU’s.
Each pin on CON10 and CON11 can be used by a daughterboard after disconnecting it
from the corresponding function block on the STEVAL-IHM022V1 demonstration board.
