Hardware delivered to your door

Program a real EV control board from home.

The EV Embedded Development Kit puts an STM32 controller, a Smart BMS unit, CAN bus, sensors and displays on one labelled board. Built by EVI Technologies and DIYguru, it takes you from your first blinking LED to battery monitoring, motor control and vehicle networking.

Why this kit

Everything an EV control unit does, on one board

Videos explain embedded systems. This board lets you do the work: write the firmware, flash it, watch it fail, debug it and make it right.

A real BMS on your desk

A dedicated Smart BMS unit with its own STM32, a battery cell with temperature sensing, charging, a charge/discharge relay and three switchable loads. Watch a pack being charged, loaded and protected.

CAN bus, the language of every EV

An onboard CAN interface with screw terminals. Pack, send, filter and debug the same kind of frames a BMS sends to a vehicle control unit.

Two microcontrollers, like a real vehicle

One STM32F103C8T6 as the main controller and a second as the BMS unit, so you write firmware for separate control units and make them work together.

Nothing to wire before you start

Every block is built, labelled and isolated with DIP switches. Switch on the peripheral you want and spend your time on firmware, not on loose jumper wires.

Sensors that matter in a vehicle

A 3-axis accelerometer and gyroscope, a BMP280 pressure and temperature sensor, an analog input, battery temperature sensing and a real-time clock.

Two displays and real controls

A 16×2 LCD, an OLED for the BMS, a 4×3 matrix keypad, six navigation buttons, RGB LEDs, a buzzer and a relay output. Build interfaces people can actually use.

What you get

What's on the board

Each block is printed with its name and pin labels, so you can see how the circuit maps to your code.

What you'll build

15 experiments, from first blink to RTOS

Each one builds on the last, so by the end you have combined sensing, control, communication and protection in working firmware.

  1. 01

    GPIO and LED patterns

    Configure clocks and pins, then drive LED sequences. Your first STM32 program.

  2. 02

    Keypad and buttons

    Scan the 4×3 matrix, debounce inputs and build a standby → active → fault state machine, the way EV controllers change state.

  3. 03

    ADC and analog sensing

    Read the potentiometer through the ADC and work out resolution and reference voltage. Every voltage and temperature in an EV passes through an ADC.

  4. 04

    PWM and LED dimming

    Set up timers, change the duty cycle and see how power output is controlled.

  5. 05

    UART communication

    Send data between the controller and your PC to monitor and debug a running system.

  6. 06

    I2C sensor integration

    Read motion from the MPU6050, then process and show it in real time.

  7. 07

    SPI devices

    Read the BMP280 and store data in external memory, using the same bus BMS front-end chips use.

  8. 08

    LCD and OLED dashboards

    Show live readings and let the user move through menus.

  9. 09

    Motor control

    Control speed and direction with PWM, the principle behind every EV motor controller.

  10. 10

    Battery monitoring

    Measure the cell under switchable loads and control charging and discharging.

  11. 11

    Safety and alert systems

    Build overcurrent, tilt and temperature alerts that act through the relay, buzzer and LEDs.

  12. 12

    CAN messaging

    Pack battery data into CAN frames, transmit it, then filter and decode it. Standard and extended frames.

  13. 13

    Bluetooth link

    Send live readings wirelessly to a phone or laptop.

  14. 14

    Real-time clock and logging

    Timestamp readings and keep them in flash or EEPROM memory.

  15. 15

    RTOS implementation

    Split the work into real-time tasks, as production BMS and motor-controller firmware does.

Questions

Before you order

What does the kit cost?

₹10,000 + 18% GST, so you pay ₹11,800 in total. It is a one-time payment by UPI, card or net banking through Razorpay.

Can I buy the kit without joining a programme?

Yes. Anyone can order it from this page. It is also sold separately for learners on our programmes and courses, so it is not part of a course fee.

Which microcontroller does it use?

The STM32F103C8T6, an Arm Cortex-M3 device. The board has two of them: one as the main controller and one as the Smart BMS unit.

Do I need to solder or wire anything?

No. The blocks are already built and labelled, and DIP switches connect or isolate each peripheral. You will connect the board to your laptop to program it.

Do I need experience in embedded systems?

No. The experiments start with GPIO and LED control and build up to CAN, motor control, battery monitoring and RTOS. Basic electronics and some C will help you move faster.

Is it safe to use at home?

The board runs from a single low-voltage cell, not a high-voltage traction pack. Treat the lithium cell with normal care, and follow the polarity markings and experiment instructions.

What do I need besides the kit?

A Windows, macOS or Linux laptop that can run STM32CubeIDE.

How and when will it be delivered?

Enter your delivery address with PIN code at checkout. Our team contacts you within one working day of your order to arrange delivery, and your dashboard shows the courier and tracking number once it ships.

What if the kit arrives damaged or with a part missing?
