Sensors & Modules for Robotics, IoT & Automation

Expand your microcontroller with 16 digital I/O pins through I2C using only SDA and SCL. Suitable for buttons, LEDs, relays and control circuits.

The 3-6V 400KV High Voltage Generator Boost Module converts a low 3V to 6V DC input into a high-voltage pulse output using an internal boost circuit. Its compact size and simple two-wire input make it suitable for high-voltage experiments, scientific demonstrations, ignition systems, and educational electronics projects. The module requires only a suitable DC power supply and switch for operation.

Warning: This module generates extremely high voltage and should only be handled by experienced users following appropriate electrical safety precautions.

The TTL FTDI USB to Serial Converter is a reliable FT232RL-based USB-to-UART module designed for programming, debugging, firmware flashing, and serial communication. It supports 3.3V and 5V output levels through a selectable solder jumper and features a DTR pin for automatic reset, making it ideal for Arduino Pro Mini and other microcontroller projects. Built-in TX/RX LEDs provide real-time data activity indication, while the Mini USB interface offers convenient PC connectivity. With data speeds up to 1 Mbps, it is suitable for GPS, GSM, robotics, embedded systems, and electronics prototyping.

The USB to TTL Serial Converter Module is a reliable interface board for connecting computers with microcontrollers and TTL-based devices for programming, debugging, and serial communication.
