Review: Works with MMDVM hat and Bluedv - There is no information included with the board, but the info needed is in the pictures and description. Download the driver from Sparkfun, put the switch in the “A” position, put the MMDVM hat on, and go. It has the same footprint as the Pi Zero and fits in a standard Pi hotspot case. No complaints so far.
Review: Missing chip - Got the board, put it together, and had to put it away. Life gets in the way. Got it out and couldn't get it to work. Got looking closer and it is missing the chip above the x1 spot. No wonder it won't work. Please help me. *Update* Quick response from the company. Sent me a new board that works as intended. Thank you for the quick response!!

### ⭐⭐⭐⭐ Yes it works. Useful little device.
*by D***N on January 29, 2023*

I have used the original Bluetooth version of the this device (BLUESTACK)so I was curious about this AURSINC USB to Serial Hat board . I decided to try it out with a AURSINC MMDVM HS HAT. I have been building HOTSPOTS since 2017 and I have used all sorts of boards to make my hotspots . Pi 2's, ZERO W's, and Pi 3's with and without displays. I got it to work on Windows with the most recent version of Blue DV for Windows on Serial and I got to work on Android Serial OTG with a Galaxy Z Fold 3. Then I decided to push my luck and tried a ZUMSPOT board from 2016 and it worked too. Don't waste your money on a MMDVM Hat with OLED is it not supported with BlueDV also you can only use D-STAR, DMR and Fusion. Those are limits with BlueDV. Now I need to go find my 2 Original Bluestack boards. Since the MMDVM USB with MMDVM HS Hat is the same size as the PI Zero W and MMDVM Hat I 3D Printed a nice case for it too. I have been using it with MY ID-51a need to try it on the other modes. A fun weekebd project and I didn't have to pull out any of my remaining hair.
