Circuit board for a remote control car/vehicle (Arduino or ESP-IDF)

Details

Loco.Engineering car/vehicle module is a circuit designed for remote control battery-powered cars and other movable vehicles (such as cranes, boats, trains, etc). A car/vehicle can be controlled from a web browser on phones, tablets and computers or by a remote controller (we provide code examples to develop a remote controller).

Main features

  • 6 layer PCB with everything you need to build a RC battery-powered car/vehicle with realistic physics even in small scales (1/87 and bigger)
  • Based on ESP32S3 - Dual-core XTensa LX7 MCU, capable of running at 240 MHz with 4MB flash memory and 2MB RAM.
  • Control up to 2 DC motors and similar loads with 2 new DC motor drivers from **[Texas Instruments](https://www.ti.com/)**, total current up to 3A, Back EMF, and current sensing.
  • Control up to 2 servo motors.
  • WiFi/BLE connectivity.
  • Battery charging - you can connect a li-poly or li-ion battery with a nominal 3.6V.
  • Built-in audio amplifier - just connect a speaker and you can play sounds from your vehicle.
  • Source available firmware based on Arduino and ESP-IDF, including special firmware for a remote controller. Check the repository on GitHub.
  • 7 GPIOs with PWM to control lights and other loads.
  • Battery level indication.
  • I2C and SPI to connect external sensors like gyroscope.
  • 5V and 3.3V outputs.
  • The smallest circuit with such features available on the market that fits even vehicles in scale H0 or 1:87, dimensions - 15mm x 27mm.
  • Over-the-air updates.
  • Firmware updates every week.
  • Designed and produced in Europe.
  • Available in 2 versions - bare circuit and with soldered wires.
  • Fast and friendly support.
  • Costs less than buying development modules with components and soldering them together.
  • Commercial license available for everyone including small indie brands and manufacturers without any "leave you phone number, we'll discuss details". We charge a small fee (2%, max 2EUR) per each sold product with our hardware and firmware without any additional fixed and initial fees.
  • Possibility to connect UWB (Ultra-wideband - https://en.wikipedia.org/wiki/Ultra-wideband) modules for indoor tracking with accuracy in a few centimeters.
  • Possibility to connect an NFC reader.
  • Car modules can communicate with other car modules to make your layout more interactive or just play with friends.
  • Removable USB type-C for charging and firmware uploading.
  • Possibility to connect your own charging module - for example, wireless charging.
  • Zero vendor lock-in, you can change the firmware as you want.

What remote-control battery-powered projects can you build with the Loco.Engineering car/vehicle module?

The module features 2 DC motor drivers capable of controlling 2 brushed DC motors, 5V and 3.3V outputs, and 7 GPIOs for connecting servo motors and other sensors, NFC readers, and UWB modules. Here are a few examples of projects you can create with this board:

  • Cars for your train and city layouts where cars follow magnetic links.
  • Small RC cars where you can use only a brushed DC motor for steering because there is not enough space for a servo motor. The module has 2 independent DC motor drivers, allowing you to use 2 DC motors in your car.
  • Any battery-powered vehicles such as cranes, boats, etc.
  • RC cars with steering powered by a servo motor and realistic physics.
  • RC battery-powered trains that require 5V or less.
  • Convert your favourite Hot Wheels and other cars to a remote control car
  • Create interactive layouts with cars, traffic lights, movable infrastructure objects (for example, garage doors), displays, sound

How to control a car/vehicle with the Loco.Engineering car module:

  • Using a remote controller over ESP-NOW. Firmware and schematic examples with 2 joysticks powered from a battery are available in our git repository. The kit with all required components to build a remote controller is available at our online shop.
  • Over WiFi from a browser on a mobile device or computer.
  • Over BLE from a browser on a mobile device or computer.
  • Over USB from a computer (on our roadmap, expected release in June).
