I am interested in RusEFI NANO module for small 1 or 2 cylinder engine. I've seen module in SHOP, but can not find information about schematic. Can you post shortcut in github with hardware details?

https://www.shop.rusefi.com/shop/p/nano is a closed-source design

Do you have any specific questions you think we should document somewhere?

We have seen RusEFI MICRO and fount it very good for 4 cylinder engines. We would like EFI for 1 or 2 cylinder light RC plane engines. Does NANO board
has the same principles as MICRO? The same IC set?

Yes, pretty close.

Can you disclose schematic?

Hi!
What the difference between OUT_IGN2 pin and OUT_IGN2_SMART pin? I just truing to connect rusefi nano to my 50cc scooter engine. Do I need drivers for the injector control signals or are these drivers in the EFI compression and just connected directly? Is there something wiring schematic for RusEFI NANO with all necessary additional equipment?

I am not sure what is "EFI compression" sorry, please help.

"smart coil" is popular EFI terminology to describe different kinds of ignition, you scooter probably has "dumb" kind - hopefully it's not CDI on your scooter.

I've just improved naming and comments on https://rusefi.com/docs/pinouts/nano/

nano definitely has on-board drivers for high-z injectors which are more or less the only kind we care about these days unless GDI

Thanks a lot. "EFI compression" means "EFI connection' sorry for typo. As far as I can get all equipment should be connected directly without drivers and adaptors.

Does the Nano accept a hall effect sensor for the crank trigger? Can the analog inputs be used as digital input? I am thinking this could be used as a methanol controller with rpm / boost .

just updated https://rusefi.com/docs/pinouts/nano/?connector=26-4&pin=3D

Thanks for the update AndreyB.

I ordered a nano for some testing. Would it be possible to update the Pinout with the MCU pins for each signal? I use lua scripting like: local enableWmiTank = readPin("PB4") . I would need to know the processor pins for my lua scripting to work.

Hi, group.
I have some questions about CKP+ and CKP- pins. A guess it crankshaft position sensor's pins. I would like to use 3-pins sensor 237314M50B with internal driver. Can I use it with RusEFI NANO?

Yes
Keywords: VR, Hall, digital

Hi, group.
Can I use MAP sensor with RusEFI NANO? How I can connect 7700101762 MAP sensor to RusEFI NANO? The sensor give voltage about 0.4-0.5V proportional manifold pressure.
Thank in advance.

I have a question about "dumb" ignition coil connection. Is it "cold" wire? I mean in classical connection coil connected to the 12V and IGBT key connect primary section terminal to the ground. Or IGBT connected to the 12V and should be connected to the primary section of ignition coil?

It does not works...
