Electronic

Because of the few space available arround the display, the FCU electronic card has been splited into two boards :

• Motherboard : Manage all stuff except display
• Display : support digits, leds and Pad leds for symbols and texts

Status

• PCB design [95%] : draft v2
• Arduino program [80%] : draft
• Common libraries and Arduino-Jeehell bridge [50%] : draft
• Buy parts [50%] : partial, to test and validate PCB design
• Prototype build [20%] : -
• Tests [10%] : -
• Mechanical design [5%] : -
• Final build and assembly [0%] : -
