Connecting CROSSFIRE Nano receiver
The CROSSFIRE Nano RX has much of the same feature set as the TBS CROSSFIRE Micro RX but on a
smaller form factor and without connectors. The small size allows you to save space and weight, while still
retaining the key features that make the CROSSFIRE system flexible and reliable.
Note: Firmware 2.24 or newer required! Make sure to update the CROSSFIRE TX before trying to bind the
receiver.
There are four channel outputs that can be used to connect a flight controller, servos or other R/C
equipment. Wiring the receiver requires soldering as it does not come with any headers (to reduce overall
size and setup flexibility). Break-out boards are available, both a simple servo board, and a duo CROSSFIRE
Nano and UNIFY PRO Nano on the same board.
The pads along the right side for 5V, GND, CH1 and CH2 (in the following picture) are spaced 2.54mm
apart, for normal headers. While the bottom row for CH3, CH4 and BST SCL and BST SDA are 2.00mm
apart.
To connect a R/C flight controller or servos, you only need to supply 5V from another source (Nano does
not provide voltage), GND and CH1 to CH4. For TBS gear that support BST, you need to connect GND, BST
SCL and BST SDA, in addition to 5V power for the receiver. Binding the receiver is done the same way as
other CROSSFIRE RX modules.
