FCUWOLVERINE

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

Basic features & specs

• Only lipo 2S compatibility -- Voltage control and warning, block firing if battery is too low -> see menu settings to find options relative to battery voltage
• Dwel and rof setting. Dwel is common for all mode and ROF for burst and full auto mode.
• Sniper mode with adjustable delay
• Magazin settings -- Max bb's per mag settings, blocking fire when "empty mag", alarm "near to empty", charging handle to reset mag capacity, mag switch to prevent blank fire

For more details about options and features, see menus below ;)
