DYS is releasing a new 4in1 ESC, the F20A. In this post I will share some close up photos and talk about the features of this ESC.
Thanks to DYS for sending me this ESC to test, I will be putting it in a new quad and see how easy it is to use, and how well/reliable it performs. 4in1 ESC is a great way to simply building and wiring, also allowing more centralized mass in the quadcopter. The F20A will be available here: http://bit.ly/2nlhQS6.
Specification and Features
- Power rating: 20A constant, 25A burst (10 seconds)
- 2S-4S LiPo
- 5V/12V 3A BEC output
- Dimension (mm) : 36x36x8 (L*W*H)
- Weight: 12.5g (excluding any wires), 23g including XT60 and wires
- BB2 processor, runs BLHeli_S firmware
- Supports DShot600 and Multishot out of the box, as well as other ESC protocols
There will be 10A, 20A and 30A versions.
Unboxing
The DYS 4in1 F20A ESC comes in a nice plastic box, along with nylon hardware (standoffs, nuts, screws), and some cables for ESC signals and 5V/12V power outputs.
Note that the XT60 connector is already soldered on the ESC, the wires are about 9.5cm long. I guess you can desolder it if you need longer or shorter wires for the XT60. Maybe they should have just left the XT60 unsoldered, so users could decide how long they want wires to be and do it themselves.
Motor connections at the 4 corners, great layout. Lots of filtering capacitors on there, hopefully it’s low in noise.
Personally, I don’t like these connectors. Never a fan of tiny plastic JST connectors, and while it’s might be totally okay in this case, I would prefer solder pads. Because it’s more solid, and possibly a little lighter and more flexible to work with.
The wires that come with it are PVC coated, would be so much nicer to have silicon wires instead.
Anyway you can see in the following image, this connector carries the 4 ESC signals, as well as 5V, grounds, and a BAT+ pin (to connect to the VBAT on FC if there is on).
And in the follow image, we have another connector that gives 12V, 5V and grounds.
Looks like the components are coated with waterproof material. Note that there is also a 10-pin black connector. I believe it would be used to stack a FC on top to eliminate any wire connections. Maybe DYS is secretly developing a new FC? :D
Edit (Jun/2017): We were right, the connector is designed for the new DYS F4 Pro FC.
The pin-outs are:
(JST connector here) -------- GND GND 5V S2 S1 S4 GND GND S3 BAT+ --------
Okay so far so good! I will share my build with this ESC soon, stay tuned.

That “waterproof material” is called conformal coating. It is not waterproofing. It is sprayed on high-temp acrylic. It prevents corrosion in a high humidity environment.
The “10-pin black connector” is surface mounted and would be very risky to use for stacking connections (with only 10-pin and no extra anchor…those intended for stacking have metal tabs at each end that are soldered to the board…this mfgr is being cheap) unless the board is fully secured with standoffs; see previous readers comment.
Hello, I have the 20a version of this.
i connected it to my FC everything looks great but when I connect to battery (3s) the ESC has red light is that normal? the light is next to M3 connection.
When you power yours does it have a red light too.
In the manual it does not say anything about led lights.
Great article by the way.
Have you found out what it means and if you could keep flying? Mine shows a red light now too
To make the current sensor work on the DYS F4 with the DYS 4in1 ESC can you just solder the pig tail with XT60 plug on the DYS F4 first, then run power through the board and out the 4 esc output pads to the positive and negative pad where the pig tail solders onto the 4in1 ESC. Wouldn’t that make the current sensor functional?
yes, that’s what we suggested in the article :)
but you need to take into consideration that both boards outputs 5V, would they fry each other? You might need to cut the pins that connects the 5V between them. Second problem would be the loss of vibration damping. It’s just not a very clean solution to use these boards together..
Have you out the 4 in 1 in a new build yet? I have the new F4 FC they recently put out and was looking to get this new 4 in 1 esc, but in 30a version.
My question is, if you are running the new 4 in 1 esc, how do you like them, and Vladimir said the current sensor wouldn’t be functional on the F4. Is this true, and what problems would that cause?
Sorry for the long question, a bit new to builds still, and this is my first 4 in 1 rig.
Thanx
hey Oscar, for the 4 in 1 solutions out there, is the current rating total or per motor connection? can I connect 4 motors to this that each draw up to 20A?
the current rating is per channel (motor).
Hi
I have both flight controller and 4 in 1..esc
Beware the plug that they plugin to each other when they stack is very fragile..or mine was not soldered properly
The connector on the 4 on 1 that connects to the flight controller separated from the esc board after about 5 flights..not completely but some solder joints causing escs to arm and disarm during flight..scary stuff.
Hi Oscar! Thank you for a great review and a lot of useful information you are sharing with us! You know DYS has made new DYS F4 controller. It is possible to stack it with DYS 4in1 ESC, but seems that current sensor located on F4 will not be functional. Any ideas how to fix this by simple way ? )))
Sorry i am not sure, they’ve not update me on this…
