5.1 PCAL6534 demo board, Fm+ development board, GPIO target board
The OM13541 PCAL6534 34-bit GPIO demo board is a daughter card to the OM13260
Fm+ I2C bus development board, which is part of the Fm+ development board kit
(OM13320); three I/O ports (8-bit × 3) on PCAL6534 are connected to the GPIO target
board for I/O visualization. You may download the software, user manual, and find

C-bus development board
The OM13260 Fm+ I

C-bus development board should be disconnected from your PC
before mounting the OM13541 board with GPIO target board on to it. The OM13541
board has an 18-pin female connector (J11) that connects to CN4 14-pin male connector
on the Fm+ development board (OM13260) as shown in
. Five GPIO Target
boards (OM13303) through ribbon cables connect to 10-pin male connectors (J12, J13,
J14, J15, J16) on OM13541 PCAL6534 34-bit GPIO demo board for 8-bit I/O port0,
port1, port2, port3 and port4.
