I made this case, because I like everything in one box. Installed is a Raspberry Pi 4 with a MMDVM Dualhat. You can run this Hotspot by 12V AC Adapter or with integrated Li-Ion Battery, It also works as a Powerbank.
The cap's for SD Card slot and USB port's are removable. The vent cap is glued in.
Material:
1x Raspberry Pi 4
1x MMDVM Dualhat (V1.3 MMDVM_HS_Dual_Hat Duplex Hotspot Board P25 DMR YSF NXDN For Raspberry pi)
1x UPS (With RTC & Coulometer) For Raspberry Pi SKU: EP-0118https://wiki.52pi.com/index.php/UPS_(With_RTC_%26_Coulometer)_For_Raspberry_Pi_SKU:_EP-0118
1x Nextion NX4832T035 3.5 Inch 480x320 TFThttps://nextion.tech/datasheets/nx4832t035/
2x 18650 Battery, LG INR18650HG2 3000mAh 20A
4x M3x20 Standoff for mount the complete System in the Box
4x Countersunk Screw M3x10 for the Standoff
4x Screw for mount the top to the box
You have to extend the antenna connectors
2x Delock SMA Jack 90°https://www.delock.de/produkte/G_65848/merkmale.html
2x Delock Adapter SMA plughttps://www.delock.de/produkte/G_89990/merkmale.html
2x Antenna SMA for 430MHz
Please note, i didn't make holes for the screws which hold the top with the TFT. After mounting everything, i drilled 2.5mm holes and just screw the M3 in.
It works, after 2 hours, the temperature is around 61.3°C / 142.3°F, maybe you have to mount a fan when you work in hot areas.
Use at your own risk.
