### ⭐⭐⭐⭐⭐ Ideal DIY hotspot solution for DMR and other digital modes
*by M***F on October 20, 2025*

### ⭐⭐⭐⭐⭐ Works well for WPSD Hotspot.
*by J***M on December 30, 2025*

Works great with my rasperry pi 5 8gb to operate a wpsd hot spot!

### ⭐⭐⭐⭐ Incorrect Firmware Upgrade Instructions
*by A***R on November 2, 2025*

I would have given this 5/5, but the instructions for upgrading the firmware were incorrect. You only need to connect the JP1 connection to unlock the firmware for flashing. If you try to also jumper the boot connections, it will yell at you. Otherwise, awesome little product, does exactly what it says it will. And having duplex connectivity really makes things seamless.
