A plug-and-play development board designed to skip messy breadboard wiring. Features onboard L293D, stepper ports, LCD pre-wiring, and dedicated slots for Bluetooth, Wi-Fi, GSM, and RF transceivers.
The onboard L293D driver is pre-wired in a fixed-enable configuration (conserve GPIOs for sensors; direction-only inputs, no PWM speed control). Standard female Arduino headers might require male extension pin headers depending on setup preference.
Product Overview
Everything Pre-Wired. Nothing to Guess.
The DSIB Universal Robotics Trainer Board is designed for students, educators, and robotics enthusiasts. Breadboard circuits are easily bumped, prone to loose wires, and tedious to debug. This trainer board integrates all essential components—such as power regulation, motor drivers, and standardized sensor ports—directly onto a professionally manufactured, solder-masked PCB.
🔌
Standardised Sensor Ports
6 sensor ports (ST-A1 to ST-A4, ST-B1 to ST-B2) — 4-pin standard (VCC · GND · DO · AO). Compatible with 100+ sensor modules. Swap without rewiring.
⚙️
Onboard L293D Motor Driver
Controls 2 DC motors via direction input pins. Enable pins hard-wired to VCC for immediate operation. No external motor shield required.
🔄
ULN2003 Stepper Driver
Onboard stepper motor driver for 28BYJ-48 and similar unipolar stepper motors. Pre-wired 4-wire digital interface.
🦾
6-Channel Servo Interface
Dedicated servo headers SM1–SM6 with PWM signal routing. Supports SG90, MG996R, and standard hobby servo motors.
📡
4 Wireless Module Slots
Dedicated onboard slots for Bluetooth (HC-05), Wi-Fi (ESP-01), GSM (SIM800L), and NRF24L01 RF transceiver. Pre-routed to Arduino GPIO.
⚡
Multi-Voltage Power Rails
Onboard regulated outputs: 5V, 3.3V, 4.2V (GSM supply), and 12V motor rail. Resettable fuses on motor outputs. Bridge rectifier for polarity protection.
Perfect for Engineering College Labs
Standardize your robotics and microcontroller practicals. With every board pre-mapped to identical GPIO channels, lab instructors spend zero time troubleshooting loose wire connections and can focus on teaching C/C++ programming and hardware automation.

Common Queries Answered
Which Arduino boards are compatible with this trainer kit? +
This trainer board is designed for any Arduino Uno-compatible board. Standard Arduino Uno (DIP or ATmega328P), clones, and Uno-form-factor compatible boards all work. Note that standard female headers on the Arduino may need to be replaced with stackable connectors or male pin headers depending on your connection preference. Contact us if you require a specific connector configuration.
Why is PWM speed control not available for the motor driver? +
The L293D motor driver on this board uses a fixed-enable configuration — the enable pins (EN1, EN2) are permanently connected to VCC. Only the direction control pins (IN1–IN4) are routed to Arduino GPIO. This design conserves 2 GPIO pins for other sensor and module I/O, which is critical when running multiple peripherals simultaneously. For applications requiring speed control, an external PWM-capable motor driver (such as L298N with separate enable wiring) can be used alongside the board.
What external components do I need to purchase separately? +
The base kit does not include sensors, motors, wheels, or wireless modules. You will need to purchase these separately based on your intended projects. Required components typically include: DC gear motors (×2), wheels/tyres (×2), robot chassis, 18650 Li-ion batteries (×2) with holder, and the specific sensor or wireless modules for your project (e.g., HC-05 for Bluetooth, MQ-2 for gas detection).
