Vin (Pin 2)
Vin is the power input line to the Subeca Module. The device sleeps at about 300uA, runs around 20mA and
can pull as much as 50mA of power during LoRa transmissions. The power input range is 3.1-6V.
ADE (Pins 3, 4, 18)
The Subeca Module has the ability to connect to a serial ADE meter. Only one wired meter may be connected
at any one time, so either the ADE or pulsed-meter input may be used, but not both. Connect pin 3
(ADE_TX/CK) to the clock line and pin 4 (ADE_RX) to the receive line. Then, enable the ADE functionality
using the Subeca Android App. Pin 18 (ADE_ENBLE) can be used to enable the ADE power supply.
Pulsed Meter Connection (Pin 10) and Meter Boost Voltage (Pin 8)
The pulsed meter input is highly configurable and versatile. It can handle inputs as high as 50V. It is possible to
apply a voltage to this meter line if the metering device requires external power. If the Subeca Module is
configured to use apply power to the pulsed meter input line, then an external supply should be connected to
pin 9 (V_BOOST_M) and the Subeca Module will enable this supply line using the (BOOST_M_ENABLE) logic
line. It can also monitor this voltage with the V_BOOST_M_SNS line. There is a 4.99K ohm pullup resistor to
this voltage which can provide up to 2.4mA (at 12V) of current to an external metering device. The circuit is
shown below, where METER is the pulsed-meter input line and METER_MCU is the line that goes to the
processor.
GPIO (Pin 5)
This configurable GPIO can be set up as an input or output but is not currently functional without additional
application code.
