Hi everyone, I’m Mirko, and today we’ll see how to connect ESCs to flight controller. In this tutorial we will examine all possible cases that we may encounter, combining all ESC types with all Flight Controller types. Let’s start with the ESCs, we can only have two models, ESC 4in1 or ESC single. The operation of ESCs is always the same, the only difference is that in the 4in1 the 4 ESCs are soldered in the same card. Both the 4 in 1 and the single ones can have cables for telemetry and current sensor. These two cables can be removed without any problems because they’re not needed to run ESCs, I personally always remove them. For the Flight Controllers we have 3 possible cases. Flight Controller with integrated PDB and ESC pads; Flight Controller with integrated PDB, but without ESC pad; Flight controller Without integrated PDB and without ESC pads. Let’s try to better understand the differences between the various flight controllers, refer to the instruction manual to find out what type yours is. The first case is the flight controllers All In One, These Flight Controllers have both ESC pads and integrated PDB. Flight controllers with integrated PDB can be connected directly to the Li-Po battery as they already have the 5V BEC in the board. This type of Flight Controller is the most versatile, as we can connect single ESCs or 4 in 1 without any particular problems. We start by connecting individual ESCs As you can see, I soldered the ground wire into the GND, the positive in the pad-plus, and the signal cable in the corresponding pad. This type of Flight Controller also has pads to connect the XT60 connector, that way we’re ready to use it. Now we see the same flight controller connected to ESC 4 in 1. In this case, I connected the XT60 connector directly to the ESCs. The signal cables must be connected according to the order of the betaflight motors: ESC N°1 to signal N°1, ESC N°2 to signal N°2, ESC N°3 at signal N°3 and ESC No. 4 to signal No. 4. As you can see for ESC 2 and 4, I have made small extensions because the wires were too short. I powered the flight controller using the ESC cables, soldering them in the pads where I had previously connected the XT60 connector The second type of flight controller is the one with integrated PDB but without PAD for ESCs, Also in this case we can connect without problems the lipo battery thanks to the integrated BEC. Let’s start by connecting 4-in-1 ESCs to this flight controller. Usually when we have 4 in 1 with a flight controller like this we can make the connection using the connectors in the boards. If ESC and flight controller belong to the same stack there are no problems, but if you use ESCs with a different brand of Flight Controller, most likely the pinouts don’t match. In this case it is necessary to have the diagrams and connect the motor, power and ground cables together. The power cable is usually called VCC, BAT+, B+ or similar. On the ground, we can find GND, G, or the like. For sengale cables we can have ESC1, M1, S1 and so on. In some cases, we have wires called nc wires, this means “not connected”. or wires where there is no input, which can be easily removed. As I have already said the wires Current and Telemetry we can remove them because they are not necessary. So we connect B+ with VCC; GND with GND; M1 with ESC1; M2 with ESC2; M3 with ESC3; M4 with ESC4. Let’s remove the other cables. At this point we can proceed by creating a Custom cable by soldering the two cables together and protecting them with heat-shrink. Alternatively, we can use the ESC connector and reposition the cables correctly. We pull up the tab of the connector with a cutter, we pull out the cable and reposition it in the right place according to the pattern of our components. Now let’s connect this type of Flight Controller to individual ESCs. In this case, since the card does not have pads for ESC we are forced to use a PDB. PDB, short for Power Distribution Board, is used to distribute the battery current to all esc and to the Flight controller. Usually in PDBs we also have a 5V BEC and a 12V BEC for peripherals that cannot be powered directly from the battery. As you can see, I connected the four ESCs to the corners, the XT60 connector and the ground and VCC cables that will power the flight controller. In this case I’m carrying the direct battery voltage because the flight controller has the integrated BEC. Now we just have to connect the signal and power cables to the Flight Controller. Once again, we connect the ESCs according to the betaflight engine order. So let’s connect signal N°1 to motor N°1, signal N°2 to motor N°2, signal N°3 to motor N°3, signal N°4 with motor N°4. Finally, we connect ground to ground and power to power. The end result will be this. If you use this type of flight controller my advice is to prefer ESC 4 in 1, because with single ones you have to use a PDB, by adding an additional stack to the build. The last case we’re going to run into are those Flight Controllers. that don’t have ESC pads or integrated PDBs. This means they need 5V to be powered, because if we connect them to the battria without a BEC, we’ll burn them immediately. The easiest way to power the flight controller is to use a PDB with integrated BEC. Alternatively, you can find single ESCs or 4-in-1 ESCs with integrated 5V BEC. Find ESCs with integrated BEC is rare because manufacturers to keep costs down are no longer putting this component on their ESCs. In any case, even if you have ESCs with integrated BEC, a PDB is always necessary. With single ESCs because you need pads for connection, with the 4 in 1 ones because you need pads to power the camera and VTX. We start with individual ESCs. As always, we connect ESCs in the 4 corners but this time we solder the power cables to the 5V output. At this point we locate the motor and power pads to make the connections. In this Matek f405 the pads are below so we weld 5V, ground and engines according to Betaflight’s scheme. On this SPRacing F3 the engine pads are these above, for feeding we can use any of the positive and negative pads of the files below. The end result will be this, as always, I connected motor 1 to signal 1, motor 2 in signal 2, Motor 3 in signal 3 and motor 4 in signal 4. Finally, let’s see how to connect 4 in 1 on this type of flight controller. Not being able to feed the card directly from ESCs we connect the power supply in the PDB that will provide to give the 5V output to power the flight controller. The end result will be this, as you can see we have a stack of 3 boards. In my opinion it is quite cumbersome and may not work well for more compact frames. If you have a Flight Controller with no ESC pad and no PDB I recommend that you avoid the 4 in 1 because you may have difficulties with the build, The ESCs can be selected individually for a more compact system.
