Take an old Android phone you may already have lying around.

- Remove any SIM card

- Install VOIP softphone app and configure with WiFi.

- Go enjoy the $175 you didn't spend on this.

maybe read the specs first?

my old phone doesn't have:

20 pin programmable header on back of phone (including SPI, UART, I2C)

I2C Qwiic port (a lot of adafruit sensors have qwiic ports)

and code that i can modify in arduino ide

But your old phone probably has USB or Bluetooth with which you can connect some cheap board with all the pins you desire.

Your android doesn't natively support all hardware communication protocols like I2C, SPI, and UART... It's still a walled garden without access to the source code. You can't modify the firmware, drivers, or hardware behavior.

They have it on their website. They make an RC Car with it.

But I can make an RC car without it too. It’s a WiFi RC car. I too am curious who wants to modify a WiFi phone’s firmware and for what.

I also couldn't imagine what one was supposed to do with phone apps. The thought was: If functionality is useful just add it in hardware or to the OS?

I guess there will be awesome niche applications for this phone that are supper useful to an audience of one person.
