Texas Instruments LM324 Low Power Quad Op-Amp SMD ICThe LM324 IC consists of four separate, high gain, internally frequency adjusted operational amplifiers designed to operate across a wide voltage range from a single power source. It is also feasible to run on split power supplies, and the low power supply current drain is unaffected by the size of the power supply voltage. The default input offset voltage is very low which is of magnitude 2mV. The operating junction temperature ranges from 0C to 70C

A small red and blue bi-colour 3mm light-emitting diode with a common anode that produces consistent light and consumes little power

and it may be turned down by software with very little standby current

This boost converter is an excellent complement to the DSO138 oscilloscope kit

These are Metal Film Resistor with a value of 39k ohm 1W and tolerance of ±5%

Only one external resistor is required to set the segment current for all LEDs
