Buttons are connected to pin headers marked IH1-IH8 on board.
Note 1: On the boards before revision v1.2.2. right side of pin header IH7 is labeled incorrectly like this (top to bottom):
R5-R6-R5-R6-R5-R6-R5-R6
Correct labeling is this: R5-R6-R6-R5-R7-R8-R8-R7
Thanks to Jazzy Gerard for reporting this!
Note 2: On boards v2.2 and above, row/column numbering starts from 0 (R0-R7, C0-C7).

Note: On OpenDeck boards before v2.0 only 16 3v3/GND connections are available on the analog section on the board. On these boards daisy-chained 3v3/GND connections should be used in order to be able to connect all 32 analog components. On OpenDeck board v2.0 and above all three pins (GND, signal, Vcc) are available for all analog components.

LEDs are connected to pin headers marked OH1-OH8 on board.
Note 1: This board already contains resistors for LEDs, so external ones aren't required.
Note 2: The M board variants using the MAX7219 LED driver chip (from v2.2 onwards) don't support individual LED brightness control.
