Heltec LoRa32 V3 Meshtastic Case with Encoder/Buzzer/Vibro/GPS/Environment sensor/Belt clip/M5Stack CardKB Keyboard-ready

### Differences of the remix compared to the original This is a customized 3D model of an enclosure designed for the Heltec LoRa32 V3 board. The original design was created by slabua, and this remix adds several important improvements:

* **Enlarged GPS antenna slot** to fit a larger GPS antenna. * **Relocated lid mounts** to provide space for a pigtail connector without obstruction. * **Added cutout for a vibration motor**, allowing optional haptic feedback integration. * **Integrated belt clip mount**, making it easier to attach the device to your belt or strap.

### Printing Recommendations:

* **Use adaptive layer heights** (up to **0.2mm** max) for optimal surface quality and faster print times. * **Tree supports recommended** for clean and easy support removal.

**Components:**

1. **Heltec LoRa32 V3** 2. **NEO-6M GPS Module NEO6MV2** 3. **SMA Female to IPX UFL/IPX Extension Cable** 4. **GY-BME280 (3.3v)** 5. **3.7V 974058 3000mAh Lipo Polymer Lithium Battery** 6. **EC11 rotary encoder** 7. **Mini Vibration Motor DC 3V** 8. **Active buzzer  3V** 9. **HY-4P** (for M5Stack CardKB Keyboard) 10. **Antenna** (in my case 433MHz soft antenna)

### **Wiring:**


Encoder A - Heltec 5 Encoder G - Heltec GND

Encoder B - Heltec 6 Encoder Sw1 - Heltec 7 Encoder Sw2 - Heltec GND

Buzzer (+) - Heltec 45 Buzzer (-) - Heltec GND

Vibro (+) - Heltec 40 Vibro (-) - Heltec GND

GPS VCC - Heltec 3V3 GPS RX - Heltec 48 GPS TX - Heltec 47 GPS GND - Heltec GND

BME280 VCC - Heltec 3V3 BME280 GND - Heltec GND BME280 SCL - Heltec 42 BME280 SDA - Heltec 41

HY-4P Black - Heltec GND HY-4P Red - Heltec 3V3 HY-4P Yellow - Heltec 41 HY-4P White - Heltec 42

**It is possible to use a 2N2222 NPN Transistor to enable/disable the GPS module.In that case, the GPS connection needs to be modified as follows:**

GPS VCC - Heltec 3V3 GPS RX - Heltec 48 GPS TX - Heltec 47 GPS GND - 2N2222 C 2N2222 B - Heltec 46 2N2222 E - Heltec GND

### Assembly Hardware:

* **3 x M3x5mm screws** for securing modules inside the case. * **2 x 2x8mm self-tapping screws**. * **1 x M3x15mm screw** for the belt clip. * **1 x M3x8mm screw** and **1 x M3x15mm screw** for assembling the enclosure. * **6 x M3x6mm heat-set inserts** for reinforced threaded mounting points.
