The MAX3420 is a USB peripheral
controller chip with an SPI bus. This page hopefully contains enough information to help you easily make use of the device in your projects. The MAX3420 provides a very simple approach to adding a USB interface to a circuit. It uses a SPI bus to connect to your system. It does require a reasonable amount of configuration and control, so you’ll need to connect it to some form of microprocessor/microcontroller.
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]
