This is a 8MHZ Crystal. This is a low cost crystal oscillator with?oscillation frequency of 8Mhz. Crystal are normally required to provide?clock pulses to your micro controller or other IC's which require external clock?source.

An oscillator crystal has two electrically conductive plates, with a slice or?tuning fork of quartz crystal sandwiched between them. The crystal oscillator?circuit sustains oscillation by taking a voltage signal from the quartz?resonator, amplifying it, and feeding it back to the resonator. Quartz has the?further advantage that its elastic constants and its size change in such a way?that the frequency dependence on temperature can be very low.

MAX232 is a communication IC. It is used to convert TTL Signals to RS232 Signal and vice versa.?MAX232?provides RS-232 voltage level outputs (approx. ? 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to + 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.
