It has a pre-mounted FMT1030 Attitude and Heading Reference System (AHRS) and comes with the extensive MT Software Suite and USB-cabling. The FMT1030 module includes accelerometers, gyroscopes, magnetometers, 10ppm crystal, and a dedicated MCU with onboard pitch, roll, and yaw solutions.

ISL29125 Digital RGB Color Light Sensor

The ISL29125 is a highly sensitive digital RGB color light sensor but with low operating voltage and low current supply. It operates in a voltage range of 2.25V to 3.63V, consumes 0.5uA current when powered down and 85uA current utmost when it is active. The design of ISL29125 includes rejection of IR in light sources making it possible to operate normally when exposed to sunlight or used in dark rooms. The device offers two optical sensitivity ranges, Range 0 ranges from 5.7mlux to 375lux and Range 1 ranges from 0.152lux to 10000lux. This range selectivity permits the user to optimize the device capabilities for a specific application. Read more

16-button Inductive Keypad Using a16-Bit Ultra-Low-Power Microcontroller

Most systems of keypad are prone to breaking due to the moving parts and dependence on electrical contact. This system uses a 16-button inductive keypad using a 16-bit MCU. The Inductive sensing is capable of handling rugged and wet environment. It is also has low cost maintenance compared to other system in rugged and wet environment, and scalable keyboard. The system consist of a keypad assembly, MCU, two 4:1 analog multiplexers, and an inductive to digital converter. The system is supplied by a 5V USB power. A low dropout linear regulator is used to step down the 5V USB power to the 3.3V required by the LDC1314 inductive to digital converter and MSP430 MCU.

Miniaturized Pulse Oximeter

Electronic equipments for medical purposes plays a big role in saving lives everyday. It needs to be accurate in data and precise in each reading. In this reference design is a miniaturized pulse oximeter, a device that measures the changes in oxygen level in the human blood through light reflection. Read more

Centralize Light Switch using QTouch

The lighting control of modern building is now into touch panel. It provides convenience to lighting control because it becomes more compact unlike the typical 2-way switch. In this design, it features single-key QTouch touch sensor IC that have one-configurable as either a single key or a proximity sensor. Since the key outline different sizes and shapes, several combinations are possible. It is settable as toggle switch or momentary switch while the signal processing is self-calibration, auto drift compensation, and noise filtering. Read more

Wireless Relay Control using IC2262/2272 and ATmega328PB

The IC2262/2272 transmitter is powered by a 12V battery. The receiver and the microcontroller operate with a 5V power supply. The optocouplers, transistors, and relays use a separate 12V power supply to isolate the high voltage devices attached to the relay contacts from the low voltage devices use in this circuit just like the microcontroller and receiver.

MCP9600 Thermocouple EMF to Temperature Converter

A thermocouple is a device that acts as a temperature to voltage transducer. In this circuit, a type K thermocouple is inserted at the input side of the type K thermocouple adapter or connector, PCC-SMP-K-100. This design can be used in different applications such as industrial equipment thermal management, ovens, industrial engine thermal monitor, temperature detection racks, etc.
