California Eastern Labs ZIC2410 (SNAP Engine Form Factor)
SNAP Engines based on the ZICM2410P2 are available. All the details appropriate for the chip- and
module-based SNAP Modules apply to module-based SNAP Engines, with the following additions.
SNAP Engines based on the ZIC2410 should not be used on the Synapse SN111 End Device board.
The power-up state of the pins conflicts with the relay controls on that board.
Just as the module exposes fewer pins than the chip, the SNAP Engine based on the module is further
reduced. Pin 10 and pins 12 through 15 are not brought out to GPIO pins on the SNAP Engine
footprint.
Separate Analog Input Pins
Unlike many of the SNAP platforms, the analog input pins on the ZIC2410 do not overlap any of the
digital IO or other peripherals. On SNAP Engines based on the ZICM2410, the analog pins are not
available by default. You must enable each analog pin you want to use by jumpering one pair of pads
and cutting the trace between another pair of pads on the underside of the SNAP Engine, which
disables the associated pin as a digital I/O.
Analog Channel SNAP Engine GPIO Pin Short Pad Cut Trace on Pad
ACH0 Pin 14 R1 R6
ACH1 Pin 13 R2 R7
ACH2 Pin 12 R3 R8
ACH3 Pin 11 R4 R5
Once enabled on the hardware, you can read the analog channel as an 8-bit calibrated value or a 16-bit
uncalibrated value, just as you can with the modules when they are not on the SNAP Engine form
factor.
