A FCU for Wolverine airsoft HPA system

Small Presentation of the project

It's an custom hand made fcu based on arduino nano. i've some options like marg switch and charging Handle connection. In addition to standards mode like semi, burst and full auto, a sniper mode is available. Unfortunately, no shotgun mode due to lack of nozzle poppet solenoid

For the switch, use something like this : https://aliexpress.com/item/32847441181.html?spm=a2g0o.order_list.0.0.8b0b5e5brNzxPX&gatewayAdapt=glo2fra
