Adding Extra I/O with the Zynaptik Module (view source)

=== Introduction ===
The Zynaptik module includes extra circuitry that is not soldered. You can solder on it 3 extra submodules and a 40 pin header for interfacing them:
The zynaptik module provides:
* 3 standard MIDI ports (IN, OUT, THRU)
* 16 x digital Input/Output
* 4 x Analog Input
* 4 x Analog Ouput
'''New modules''' (from 2021-04-01) include everything soldered on. Ready to work:

By the contrary, on '''older modules''' (before 2021-04-01) only MIDI circuitry is soldered on. You must solder some parts for enjoying all the functionality. You can [https://shop.zynthian.org/shop/product/zynaptik-expander-kit-379 buy the Zynaptik Expander Kit] or order the parts by yourself.

These are the ICs used by the Zynaptik:
'''+ Secondary MCP23017 (Digital I/O):''' It uses I2C address 0x21 and the 2 interrupt lines are connected to the RBPi GPIO. INTA to GPIO27 (pin 36) and INTB to GPIO25 (pin 37). The digital I/O are labelled as GPAx & GPBx on the Zynaptik's header schematic.

'''+ MCP4728 (MOD-2 Analog Output):''' It uses I2C address 0x60 by default. The 4 analog output pins are labelled as DAx on the Zynaptik's header schematic.

It's being implemented currently and it's not available on zynthian software yet.
