HotSpot MMDVM Case

thingiverse

This project is for Amateur (HAM) Radio use. You need a HAM Radio license and callsign. This is a case I designed in OpenSCAD for my MMDVM hotspot project. It is loosely based on https://www.thingiverse.com/thing:2997294 but I designed this one from the ground up. So not a true remix but I still wanted to give credit to the designer of the other case. This case is designed for the Raspberry Pi Zero W board and a hotspot board I found on eBay, along with a .96" OLED display also found on eBay. Parts: 1x Case bottom 1x Case top 1x Case frame 4x Standoffs 1x Raspberry Pi Zero W 1x Hotspot board (https://www.ebay.com/itm/For-Raspberry-pi-2018-Latest-MMDVM-Hotspot-Pi-star-Support-P25-DMR-YSF-Antenna/233145671274?hash=item3648909e6a:g:WgcAAOSww4Jcc8Wh) 1x OLED display (https://www.ebay.com/itm/US-0-96-I2C-IIC-Serial-128X64-LED-OLED-LCD-Display-Module-for-Arduino-White/322520336866) 4x M3 25mm hex socket cap screws It should be noted that the power pins on the display I used are incorrect and need to be swapped when connected to the hotspot board. Otherwise it works great. 04/26/2020 - For the display, I removed the 4-pin header and then soldered in 4 short wires I then used to connect it to the HAT in the correct order. You will also need a micro sd card, at least 2GB and an image from https://www.pistar.uk/ to make the hotspot work.
