Purpose The Apex-Link is a DIY remote controller designed for low-latency robotics and RC vehicle control, such as quad-spiders, hexapods, or racing rovers. It utilizes the ESP-NOW protocol for control without requiring a WiFi router. Practical Uses This transmitter provides dual-stick precision and real-time telemetry, including signal strength, battery percentage, and mode information via an LCD. It is intended for use as a bridge between a pilot and a machine. Included Parts - ESP32 Dev Board - 2 Analog Joysticks (X/Y axis with click buttons) - 16x2 LCD Display (I2C version recommended) - 1 Rotary Encoder - 1 SPST Toggle Switch - 2S 18650 Battery Pack (7.4V) - 1 DC-DC Buck Converter - 3D Printed Housing Included Files - controller_case_v1.stl - Controller_cover_v1.stl Printing and Assembly Guidance For the shell, use 3-4 perimeters to prevent joystick screw holes from stripping. The main body may require tree supports for the joystick cutouts. For wiring, using a small piece of protoboard is recommended to centralize the Ground and VCC rails for the LCD and joysticks.
This model is a 3D printed Landy Mini scaled at 125%. It features a modified chassis specifically designed to adapt the mechanics of a WPL-C24 and its available metal upgrades. The author reports that all holes are compatible with the assembly kit screws. Practical uses for this model include RC vehicle hobbyist builds. The motor compartment is designed to accommodate two 18650 batteries in a 2s1p configuration, and the seats are hollowed out to allow for the placement of electronics inside. Included parts consist of various STL files including the front, rear, central, and front/rear chassis components, body parts (hood, rear body, roof, fenders), interior elements (dashboard, seats, steering wheel, floor), and lighting components (headlights, rear lights, front grill), as well as a steering bar and servo mount. Printing guidance provided by the author: Material: PLA. Chassis and interiors: 0.20 mm layer height. Body: 0.16 mm layer height, no supports; place the STL files as with the Landy Mini printing.
