920MHz obi radio data link module
Umeda Electric

Without the need for wireless or electronic circuits, we will provide 920MHz radio that is easy to use for software engineers and general hobby users by allowing PC vs. PCs, PC -to -PC, substrate vs. substrates, etc. (Use a certified wireless module) ■ Current problems In recent years, the 920MHz band special small wireless technology, which has been attracting more attention in IoT sensor network applications, has become easier to use as medium -long range radio due to the revision of the radio wave law in the fall of 2014. We have developed a 920MHz data link unit that can be easily used as USB (CDC) /USART. ■ Points ･ 2.4GHz (Wi-Fi, Bluetooth, Zigbee) is less existing and has a relatively good radio environment. ･ 430MHz band has higher throughput and many channels ･ Long -distance communication is possible compared to 2.4GHz pair (over 2 km depending on the environment) ･ Prior to the revision of the Radio Law in the fall of 2014, the products equipped with 920MHz modules had to be obtained separately, but they are now alleviated. ･ Up to 50kbps ■ Specifications ･ 920MHz telemeter module using special small wireless ･ Can be connected by USB or UART (3.3/5V) ･ Operation only with USB bus power (it is recognized as a COM port from the PC) ･ Small LCD with backlight, RGB LEDX2, push switch X2, buzzer ･ The installed 32bit ARM core firmware can be upsit version by USB connection ･ Custom firmware (authentication / encryption, etc.) is also possible ･ Correspondence to the housing (made by Takachi: TWF5-2-5) ■ Applied case ･ Various wireless data communication ･ Wireless data logger ･ Telemeter 《Industry, Agriculture, Construction, Welfare, Amusement, etc.》
