The LCD Terminal just like a normal terminal, it can connect to any host via RS-232 serial cable. A PC keyboard must connect to it as the input device and what ever you type will send to host via RS-232 and display on a 40x4 LCD.
Data receive from host can also display on the LCD unit.
You can use this device as any Unix/Linux machine's console.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
