ODROID-GO Advance Cell Phone: A Custom Built and Coded Cell Phone

Recently, I decided to build my own cell phone out of an ODROID-GO Advance using a SIM800L module which included a speaker and mic. Thanks to the ample space inside the case, this hardware installation was pretty easy. For this build, I used a Debian Buster image with the SIM880L connected to the ODROID-GO Advance’s UART2.  ▶
