Inductance and Resistance meter, Arduino based. Push button input. 3 tests, 4 resistor test ranges. One Inductance test, Analog input display , outputs to serial monitor and OLED. Resistor range is from 0 ohms to 2 Mohms , Inductor range is 80uH to 30,000uH.

An SRAM IP Uniquely designed with open source tools. Static RAM is a type of random-access memory that uses latching circuitry (flip-flop) to store each bit. The size of SRAM specs is 32kbit/4k bytes with 1.8v. A 6T SRAM pairs up with two access transistors for read, write state and cross coupled inverter to hold/regenerate the state.
