Heltec T114 Case (w/ 103450 Battery and Power Switch)

This is a custom, snap-fit enclosure designed specifically for the Heltec T114 LoRa development board. It is engineered for long field deployment and durability, with easy access to all controls.

The case is designed to house a large 103450 (2000mAh) battery, which provides an impressive 9 days of operation on a single charge for the T114, making it perfect for remote MeshStastic nodes or environmental monitoring.

Key Features:

• Snap-Fit Assembly: The two halves lock together securely using internal latches. No screws or glue are required for the main assembly.

• External SMA Antenna: Features a dedicated port for an external SMA antenna, allowing you to use high-gain antennas for improved range while keeping the connector strain-relieved by the case.

• Integrated Buttons: The buttons are printed directly into the case. They are designed to actuate the tactile switches on the T114 board without needing separate button caps.

• On/Off Switch: A precisely placed opening on the side provides direct access to the node's SMD power switch. You can easily turn your device on or off without opening the case, saving power during transport or storage.

• Meshstastic Branding: A subtle "Meshstastic" logo is embossed into the front face of the enclosure.

• High-Capacity Battery Fit: Specifically designed to accommodate a 103450 prismatic cell (thickness: 10mm, width: 34mm, length: 50mm). This is a common LiPo form factor that gives the T114 extended life.

Important Assembly Notes:

• Tight Fit: The internal clips are intentionally robust to ensure the case stays closed in harsh conditions. You will likely need a pair of tweezers or a small flathead screwdriver to gently depress the internal latches when inserting the board or separating the halves.

• Board Installation: Insert the Heltec T114 at a slight angle, seating the USB-C and antenna side first. You will hear/feel a click as the board snaps past the retention clips. Ensure the SMD power switch aligns with the side cutout.

• Battery Placement: Place the 103450 battery in the bottom compartment before inserting the board.

Printing Guidelines:

• Material: PETG recommended for outdoor durability (PLA may deform in hot environment temperature).

• Supports: NO supports needed if printed with the flat side (bottom half) on the build plate. The snap features and small openings are designed to be support-free.

• Resolution: 0.2mm layer height works well.

• Infill: 10-15% is sufficient.

What you need:

• 1x Heltec T114 Board

• 1x SMA-female to U.FL pigtail

• 1x SMD switch

• 1x 103450 Battery (2000mAh)

• 1x SMA Antenna
