Devantech SRF04
Ultra Sonic Ranger Module

The SRF04 Ultra Sonic Ranger Module is a high quality ultra sonic range finder, which can easily be connected to many microcontroller's to measure/detect the presence of obstacles.

Using a 5V supply and drawing from 30mA typical. to 50mA max. The SRF04 can be connected directly to many micros without the need for a separate power supply.

Devantech SRF08
Ultra Sonic Ranger Module

The SRF08 is an evolutionary step up from the SRF04. It requires less power to operate, has a longer range (up to 6m) and it performs its own internal timing of the return echo. The SRF08 is also fitted with an LDR to measure light levels.

Communication with the SRF08 is via the I2C bus that is available on many popular microcontroller's.

Miniature Size: Only 15mm high - 32mm long - 10mm deep

Devantech SRF10
Ultra Sonic Ranger Module

The SRF10 is a miniature ultrasonic range finder, controlled over a I²C bus which is available on most popular micro controllers, (including AVR devices).

Like the SRF08, the SRF10 will operate up to 6m while performing its own internal timing of the return echo.

Devantech CMPS03
Magnetic Compass Module

The CMPS03 Magnetic Compass Module has been specifically designed as a robot navigation aid.

This module can easily be connected to many popular microcontroller's via the I2C bus.

The compass uses two Philips KMZ10A magnetic field sensors that are sensitive enough to detect the Earths magnetic field. The module generates a number that indicates the bearing of the robot in relation to the local magnetic field. This number can then be read by the microcontroller.

TPA81 Thermal Sensor Array

The TPA81 can detect a candle flame at a range 2 meters (6ft) and is unaffected by ambient light and it can also detect body heat!

The TPA81 is a thermopile array that can be used to measure the temperature of 8 adjacent points simultaneously. Moreover if used in conjunction with a servo (to pan the module), a thermal image of a heat source can be built up.

USB-RS485 Convertor

The USB-RS485 is a complete, self powered, USB to RS485 interface working at any baud rate up to 250k baud. It features automatic bus turn-around - any time your not transmitting the module is listening. Uses the MAX487 quarter power tranceiver, so you can have up to 128 devices on the bus.

USB interface uses the FTDI chip which has drivers available for Windows XP64, XP, 2000, ME, 98, CE.NET V4.2, Linux, Mac OS8, OS9, OSX.

USB to I2C Convertor

The USB-I2C module is a low cost USB to I2C module, with a simple command set, and interfacing to any I2C device.

The USB-I2C module provides a complete interface between your PC and the I2C bus. The module is self powered from the USB cable and can supply up to 70mA at 5v for external circuitry from a standard 100mA USB port. I2C Devices - Any registered or unregistered I2C device. Host support - Drivers available for Windows XP64, XP, 2000, ME, 98, CE.NET V4.2, Linux, Mac OS8, OS9, OSX. Voltage - Self powered - 5v available Current - Up to 70mA available for your own circuits On-board Pull-up resistors - 4.7k Digital I/O - 1 Input and 2 I/O available when not using I2C. Analogue Input - 2 10-bit channels available when not using I2C.
