The HA-Feather adapter board allows you to rapidly create a remote IoT device subsystem with a Adafruit Feather and a LooUQ iotQc CTA, such as our LTEM1 IoT modem.
The adapter makes all the connections you need for the Adafruit Feather (the "Feather") and the LooUQ CTA. The LooUQ software drivers use the pinout and connections of this adapter board as their default port assignments. The CTA draws power from the LiPo battery circuit of the Feather, leveraging the battery and the battery charging circuit of the Feather for both the Feather and the CTA.
Unused Feather pins such as the most of the analog inputs from routed to through-hole solder pads. Signals used by the CTA are passed through a pair of solder pads with jumper to allow for alternate GPIO mappings; simply cut the jumper between the pads for the signal you want to map differently, then solder a wire between pads to reconfigure the board.
- The adapter ties ARef to the 3.3-volt regulated output of the Feather, so if you want to use an analog reference voltage different from the 3.3-volt LDO output the jumper should be cut between the solder pads.
- The adapter board also offers a connector to supply power for active GNSS antennas directly off from the USB-VBUS pin.
- Unused Feather GPIO pins routed to a solder-pad are: SCI/SCA (I2C), A0-A4
