prusaprinters

UPDATE 19.05.2025:Added a stubby antenna cover as the original antenna just doesnt do the build justice.Simply slide the antenna in from the top and close it up on top._________________________________________________________________I tried to put as much stuff in a slim case without sacrificing runtime  ( yeah the Heltec V3 is everything else then  NOT power hungry :D)  but you get around a whole day with heavy use no problem. The Amade1 feature's GPS,  a buzzer, rotary encoder for canned messages, a max of 1800mAh battery , a Power switch and a metal belt clip,  neatly packed into a somewhat rugged case. I used brass inserts for M2.5 screws but you should be able to simply screw M3 screws directly into the plastic, of course its much nicer with the brass inserts and fitting screws. Things your going to need for this build: GPS module:GT-U7 GPS modul navigation satellite positionierung kompatibel NEO-6M 51 ein-chip-mikrocomputer STM32 für Arduino (aliexpress.com)3 volt buzzer 8.5x8.5x3mm10 stücke smd Summer 5020 7525 8530 9650 1230 9032 3V 3,6 V 5V magnetischer Mini aktiver passiver Piezo-Summer Lautsprecher elektronisches Kit - AliExpressMetal belt clip with rivets: /20pcs meetee 56x25mm Doppel löcher Metall Feder gürtel Holster Mantel Clip Verschluss Schnallen Zubehör mit 8mm Kappe Bolzen Schrauben (aliexpress.com)Heltec V3 Lora dev board: APKLVSR LoRa ESP32 Entwicklungsplatine,LoRa V3 Board mit OLED Display und Antenne USB C Dual-Core IOT Board 240MHz Bluetooth WiFi Modul SX-1262 863 928MHz für Arduino: Amazon.de: Computer & ZubehörRotary encoder: PENGLIN 10PCS 20mm 5Pins 360-Grad-Drehgeber-Codeschalter Digitales Potentiometer mit Druckknopf und orangefarbener Knopfkappe DIY-Kit für Arduino Raspberry Pi : Amazon.de: Gewerbe, Industrie & WissenschaftPower switch: 10/20 stücke 50V 0,5 EINE SS12F15 Mini Größe Schwarz SPDT Rutsche Schalter für DIY Power Elektronische Projekte g6 1P2T Kippschalter Griff 6mm - AliExpressTreaded brass melting inserts:  M1.6 (OD2.5mm)50pcsM1 M 1,4 M 1,6 M 1,7 M2 M 2,5 M3 M4 M5 M6 M8 Messing Wärme Gewinde Einsatz Mutter hot Melt Gerändelt Injection Einbettung Mutter von 3D Pringting (aliexpress.com)M1.6 Screws 5 mm 50 pcs5/50 stücke M 1,6 M2 M 2,5 M3 M4 M5 M6 M8 304 Edelstahl CM Sechs-Lappen Torx ultra Dünne Super Niedrigen Flache Wafer Kopf Schraube Bolzen - AliExpressFor use in the EU I got myself some 868MHZ Antennas ( Not suitable for the US as they use 915MHZ)Eightwood 868 MHz Antenne Kipp-und-Schwenkbar SMA Stecker NFC RFID Antenne 2 Stücke für Homematic CCU3 CCU2 CC1101 Raspberry Pi GSM Wireless WiFi Ham Radio MEHRWEG: Amazon.de: Elektronik & FotoI am still sourcing the correct battery once I found out the 2300mAh rating was wrong with the battery I used ( It actually was just a 1800mAH), ordered one but still have to verify it fits the build, then I am gonna add the info here!!31x87x7mm max battery size! In addition you will need some double sided tape for the battery and GPS PCB, solder iron and related equipment and very thin wire and of course the knowledge to do that kind of work.Tolerances are pretty tight, consider printing it  100-101% in case you have problems with assembly.
