3RIOT CONTROL USER MANUAL
The RIOT CONTROL FLIGHT CONTROLLER has been designed
by Rotor Riot pilots, built on components with proven performance.
By placing the IMU (a.k.a. gyro) in a soft-mounted case, and also
soft mounting the circuit board itself, the amount of vibration
reaching the IMU is drastically reduced - allowing the ight
controller to receive a very clean signal for easy tuning and smooth
ying.
The layout of the Riot Control FC has been designed with building
and repairing in mind, keeping related wires grouped together to
eliminate unnecessary board crossing. The Riot Control FC has 3
UARTs available for peripherals like serial receivers, VTX telemetry,
and more. The Riot Control FC also has an integrated Power
Distribution Board (PDB) enabling all electronics to be connected
without the need for an external PDB.
The Riot Control FC features inversion jumper pads on UART
1, so it can be used both for inverted SBUS protocols as well as
non-inverted protocols such as DSMX or CRSF. The board has a
9V voltage regulator built in for your camera and VTX to ensure
noise-free video. We are proud to bring you a board that will deliver
simple wiring and smooth ight.

The Riot Control FC features connection points on each corner
for use with individual ESCs, as well as a pinned connector on the
underside for use with a breakout cable and a 4-in-1 ESC board.
INDIVIDUAL ESC
For individual ESCs, the connection is very straightforward. At
each corner, connect the positive wire of your ESC (thick, red wire)
to the large pad labeled V+. Connect the thicker ground wire of
your ESC (thick, black wire) to the large pad labeled V-.
Connect the signal wire of your ESC (thin wire, usually white or
yellow) to the small signal pad labeled S1/S2/S3/S4, and the signal
ground wire of your ESC (thin wire, usually black) to the small
signal ground pad labeled -.

4-IN-1 ESC
You can also use a 4-in-1 ESC Board with the Riot Control FC. In
this case, use the break out connector located on the underside of
the board.
WARNING: You must ensure the connector is pinned properly for
your ight board and 4-in-1 board.
Currently there is no standard wiring order, so the order of the
pins and wires may vary between the Riot Control FC and the 4-in-1
ESC board of your choice.
Looking at the underside of the board, the order of the pins on
the Riot Control FC Breakout Port is as follows:
PIN Function
1 GND
2 BAT + input
3 Current Sensor
4 GND
5 Motor 1 output
6 Motor 2 output
7 Motor 3 output
8 Motor 4 output

UART stands for Universal Asynchronous Receiver Transmitter.
UARTs are used on Flight Controllers to transfer data between the
ight controller itself and external devices such as a radio receiver.
Each UART port has a receiver (RX) for input and transmitter (TX)
for output. If the ight controller is accepting information, such as in
the case of control link receiver, the RX pad will be used. If the ight
controller is sending information, such as commands to the video
transmitter, the TX pad will be used.
The table below outlines the Riot Control FC’s UARTs and their
recommended uses. Only one function may be assigned to each
UART. For example, if UART1 is used for the receiver, and UART6
is used for VTX control, UART3 can only be used for one of the
follwing functions: ESC telemetry, RunCam Split control, FrSky
S.Port Telemetry.
UART OVERVIEW

UART INVERSION
For UART 1, you will notice the table explains that you are
required to bridge pads depending on whether you are using a
FrSky or Spektrum receiver. This is because FrSky receivers send an
inverted signal. For the ight controller to understand it properly it
must run through an inverter.
The Riot Control FC has a built in inverter, which can be either
enabled or disabled by bridging two pads on the ight controller.
Bridging pads B and SBUS enables this inverter, and bridging pads
B and DSM bypasses it.
Inverter Enabled Inverter Disabled

10 RIOT CONTROL USER MANUAL
Connection for your FrSky Receiver is provided via the UART 1
solder pads located in the bottom connection rows.
Connect the SBUS OUT wire coming from your receiver to the
RX1 (inv) pad on the Riot Control FC. Bridge pads B and SBUS as
instructed on page 9 to enable signal inversion for UART1 (required
for S.Bus.
If you want to use FrSky Telemetry, Connect the SmartPort
wire from your receiver to the TX1 pad von the Riot Control FC.
Additional setup is required (see Page 21).
