¶ Controller Core
The core board is the heart of CyberBrick, offering logic control, wireless connectivity and programming capabilities. All current CyberBrick projects use the same core board, giving creators a unified development standard and enabling users to switch between different projects without buying multiple expensive main control boards.
Based on the ESP32-C3 microprocessor (MCU), the core board provides key GPIO pins and supports Bluetooth and WiFi connectivity. It comes with CyberBrick’s unique underlying runtime library and Bluetooth-upgradable firmware. Creators can develop with MicroPython at the application level. For programming details, refer to the Code Repository.

¶ Functional Shields
The core board's computational power must be complemented with various peripheral devices to create interesting applications. In CyberBrick's first - batch projects, remote - controlled vehicles are the most common application, which often use output devices like motors, servos and LEDs on the vehicle, while the remote controller needs to read signals from input devices such as buttons and joysticks. Therefore, we've launched two functional shields for the transmitter and receiver ends. They convert the main control board's GPIO into peripheral device interfaces and incorporate additional circuits for driving motors.
CyberBrick also has advantages over traditional development boards, thanks to its standardized, solder-free connectors and standard libraries. Users can simply plug in the required modules as per the instructions and call the corresponding software controls. This eliminates the need to worry about interface and voltage compatibility or search for the necessary code libraries.

¶ Input Module
Input modules, like joysticks, buttons, and touch sensors, capture user actions or environmental changes and convert them into system - recognizable signals. When you push a joystick or press a button, the system receives the corresponding control commands via these modules.
¶ Single-Axis Joystick Module-XA009
Single-channel joystick modules are single-axis analog input modules that auto-center when not in use. Unlike dual-channel joysticks, they move in one direction, outputting a single analog signal. They're ideal for controlling speed or position in independent motion systems.
For instance, in a vehicle model, one module can control speed while another handles steering. In a tower crane model, it can control hook height. On a tracked vehicle, two modules can separately control each track's speed.
¶ Hardware Connection
Connect the single - channel joystick module's terminal to an SH1.0 - 3pin cable, and link the cable's other end to the analog input ports on the remote transmitter board's sides.
¶ Software Configuration
Behavior control allows devices to output corresponding to the analog values of designated channels. It's commonly used for controlling motor speed or servo angles via joysticks. You can view the hardware connection status of the receiver, including motor devices, by checking "Hardware Connection" beside the motor devices.
Event control divides each channel's values into three cases (greater than, equal to, or less than the median), allowing you to control a device's status. It can link actions, like connecting turn signals to steering movements.
If the joystick drifts after centering, use parameter settings to perform mid-point calibration and adjust the dead zone size.
¶ Dual-Axis Joystick Module with 3Pin SH1.0 Connectors-XA011
A dual-channel joystick module is a two - axis analog input device that automatically centers when not in use. It's suitable for controlling both speed and direction in scenarios where movements are interrelated. For instance, in vehicle models, one axis can control movement speed while the other steers. In crane models, one axis can handle rotation and the other controls distance.
¶ Hardware Connection
Connect each end of the dual - channel joystick module to an SH1.0-3pin cable, and plug the other ends of these cables into the analog input ports on the sides of the remote transmitter board.
¶ Software Configuration
Behavior control adjusts a device's output to match the analog values of a designated channel. It's often used for joystick-based motor speed or servo angle control. Checking "Hardware Connection" beside motor devices lets you see the receiver's hardware connection status.
Event control splits each channel's values into three cases (greater, equal, or less than the median) to control device status. It can bind actions, like linking turn signals to steering movements.
If the joystick drifts after centering, use parameter settings to perform mid-point calibration and adjust the dead zone size.
¶ Three-Position Rocker Switch Module-XA010
A 3 - position switch module is a single - channel analog input module with three switch positions representing three states.
It can be fixed in left, center, or right positions, making it ideal for state-switching tasks like toggling lights or transformations. For example, it can switch vehicle model headlights on/off or control multiple vehicles in a one-to-many remote control setup.
¶ Hardware Connection
Connect the 3-position switch module's terminal to an SH1.0-3pin cable, and plug the cable's other end into the analog input ports on the remote transmitter board's sides.
¶ Software Configuration
In the three - position switch module configuration interface, you can set the device status corresponding to the switch status, such light as effects, motor speed, and servo position. Suitable for switching light states and controlling model transformations.
¶ Power Switch Module-XA007
The switch board is a dual-position switch. It's used to control power on/off without removing the battery. It has two 2-pin XH2.54 ports and is usually connected in series between a power source (like a lithium battery) and functional shields (like remote transmitter/receiver boards). This allows you to cut off power without removing the battery, preventing battery drain from standby mode.
¶ Hardware Connection
Connect one side of the switch board to the power source, and the other side to an XH2.54 2 - pin cable. Connect the other end of the cable to the XH2.54 power port on the expansion board.
¶ Momentary Button Module-XA008
The momentary button module is a binary input module that can recognize various actions, including short press, long press, button down and button up.
Unlike a three-position switch, it has only two states: pressed and released, and it always returns to the released state. This module allows for cycling through modes in a set order, and triggering or stopping actions in real-time. For example, it can trigger a launch mechanism in a model or switch light modes and colors in models with LED lights.
¶ Hardware Connection
Connect the momentary button module's terminal to an SH1.0 2 - pin cable, and plug the cable's other end into the digital input port on the underside of the remote transmitter board.
¶ Software Configuration
