The WiPhone can be completely disassembled, using only 6 screws, to be repaired or re-purposed, and the whole back of the phone comes as an expansion port and prototyping area, which can be replaced with a breadboard or any custom PCB. The Arduino-compatible firmware is open and easy to understand, claims Wilson, which eases the modification or replacement of software functionality.
The 120x50x12mm phone also comes free from built-in trackers, spy tools, and cannot be triangulated from cell towers, highlights the campaign. Owners can even disable automatic firmware updates, or completely remove the stock firmware and use their own. The phone is built around an ESP32 dual core processor running at 240 MHz, it has a 2.4” screen (320x240), a 25 buttons backlit keypad (all keys being user programmable), a micro USB connector, a 3.5mm audio jack and an internal microSD slot. Its 700mAh battery gives the WiPhone an estimated 8 hours talk or 1 week standby time.
