Product idea: A Series output only board - spacerunner - 03-14-2023
Hi,
It would be nice to have the opposite of a KC868-AI board but for outputs only. Call it KC868-AO
.Maybe for 32 / 64 channels, without extras like inputs. Just the MOSFET driver lines, ESP32, ethernet RJ45 and maybe I2C, RS485 or some other serial header.
Just ordered a KC868-A128 because I wanted the output flexibility of Mosfets, but the entire loaded board is actually too much.
Having Inputs and Outputs separated and both driven by ESP32s would be awesome. It eliminates single points of failure a bit and you could physically spread I/O across wider locations by simply using ethernet.

"but the entire loaded board is actually too much" do you means the PCB too large?
do you want only have 32 mosfet output, let pcb smaller?
RE: Product idea: A Series output only board - spacerunner - 03-15-2023
It’s a bit of everything:
1. Boards loaded with many more options (inputs etc) are much more expensive in electronic parts (most important)
2. Loaded boards are bigger
3. Having the option to be modular is awesome
4. There is NO ESP32 based multichannel (16,32,64,128) MOSFET output driver on the entire market.
5. Especially the design of souring multiple voltages per 8-Block like on KinCony controllers is extremely useful, allowing to drive different relay blocks with one interface.

8 channel, 16 channel, 32 channel mosfet ESP32 board under designing
but will include INPUT port, if without INPUT ports, output can't manually control. or do you have another way for manual control extend relay?

Yes, of course. External control can be done over ethernet / Wifi (MQTT or whatever), or maybe even RS485 or I2C.
"Manual Control" by buttons etc is mostly not needed for an interface only product.
Think of an MOSFET output only board as an "EPS32 programmable output interface". Like the KC868-AI is for inputs.
It's also good for extensions. That's why I would not start below 32 channels.

ok, thanks for your suggestion, will make a AO (32CH mosfet) for you
RE: Product idea: A Series output only board - spacerunner - 03-16-2023
Great
As I said in my first post, I just ordered a KC868-A128. So I don't need it right away, but it would be awesome to have for my next upcoming project. Think of it this way for many applications, for example multiple Buildings or stories:
Great: KC868-A128
Even better: KC868-AI + KC868-AO64 (Floor 1 / Building 1) + KC868-AO32 (Floor 2 / Building 2)
just as an example
RE: Product idea: A Series output only board - admin - 03-16-2023
do you use by home assistant via ESPHome?
we will make AO32 firstly, if market accept this, maybe will plan for AO64
how about the current of every channel MOSFET for load? 4A?
RE: Product idea: A Series output only board - spacerunner - 03-16-2023
My system setup is a bit different, mostly node red / MQTT based with interfaces to Home Assistant / OpenHab. So, my I/O interfaces will have custom firmware.
Most important to me: RJ45 ethernet.
MOSFET load: concept of KC868-A128 500mA 5-24V is perfect. It allows driving all kinds of interfaces while being low on power consumption. Also, keep the price in mind. 4A / channel would make it more expensive.

do you wrote your own arduino code download to ESP32?
