The service we provide

We provide a large variety of solutions connecting "Things" wirelessly for the individual requirements of our customers.

The purpose of our services is providing the wireless capability that can get easily for everyone who want to make some wireless remote monitoring/control devices but feel that it is hard to achieve.

You might be confused since there are several wireless specifications. However, each specification has its own specific purpose. The WiFi is for connecting PCs to LAN, the Bluetooth is for connecting smart phones or PCs to the peripheral devices and TWE(the Wireless Engine) is for connecting "Things" wirelessly.

The wireless microprocessor module TWELITE is utilized for connecting "Things" wirelessly such as IoT(Internet of Things) or M2M(Machine to Machine) networks.

The TWELITE is small size to fit for anything, low power consumption to last battery life for several years, long range transmission to reach for a long distance and many devices can join to the network. Every features are suitable connecting "Things" wirelessly.

The various information can be gathered or transmit using the TWELITE. The TWELITE will be a function block to add the wireless functionality building a final product.

We have prepared a plenty of application software and the development platform to customise them. We also provide the high performance antennas and the energy harvesting power management modules.

We provide the complete turnkey solutions to make product using the wireless capability.

Who is our user?

The wireless microprocessor module TWELITE is designed for the "MAKERS". The "MAKERS" means who loves making something includes engineer, artist and designer both professional and amateur.

It was not so easy to implement the wireless function into the product before. We removed the difficulty and offer usability to all of the "MAKERS". The TWELITE is able to utilized for the wide range of market such as hobby, education or industrial products.

Wireless Microprocessor Module TWELITE

The TWELITE is a IEEE802.15.4 standard complied wireless microprocessor module.

The TWELITE is not a single functioned wireless module. It's a microprocessor module that has wireless capability. It doesn’t require the external microprocessor and it makes the final product small and simple.

The TWELITE is a small all in package sized 13.97 square millimeters(0.55 square inches) includes 32 bit RISC microprocessor, digital input/output, analog input/output, PWM, comparator, pulse counter and the RF circuit.

The TWELITE controls the sensors, displays, LEDs, switches and the others without any external microprocessor. It reduces the total cost and shorten the development time.

Any software is necessary to function the TWELITE. The TWE standard app is preinstalled and it runs immediately. The app can be replaced or can be newly developed.

The TWELITE uses 2.4GHz Global Frequencies(ISM band) that is shorter wavelength. Since the wavelength is shorter it makes antenna length shorter and the final product smaller.

Complies with European EN300 440 with the CE logo, U.S FCC Part 15.247, Canadian IC RSS-210 and Japanese ARIB STD-T66.

Lead-free / RoHS product.


The TWELITE has two types of form factors. The SMD(surface mount device) and the 2.54mm (0.1in) pitch DIP device. Both of the types has the same functions but the pin assignment are different.
