2.0 5.0V & 3.3V Power Supplies
Figure 2.1 – The Chameleon PIC power supply design.
The Chameleon PIC system has a duel 3.3V / 5.0V power supply system that is feed by a single 9V DC unregulated input
from a wall adapter or feeds from the USB port header. The supplies design is shown in Figure 2.1 for reference. The
supplies are straight forward, the only interesting thing is the coupling of the USB power and the regulated power at node
1 of the power switch SW1. This allows the system to use power from either the regulated supply or the USB port. The
Chameleon PIC is a mixed voltage system to support 5V I/O and 3.3V PIC and Propeller chips. Both supplies are
independent and can each supply up to 500 mA for all your needs. Additionally, the power supplies are exported to the
expansion header J7 for external interfacing.
3.0 Reset Circuit
Figure 3.1 – The Chameleon PIC reset circuit.
The Chameleon PIC can be reset externally via a number of sources including the reset switch SW2, the ISP
programming port as well as pressing as thru the DTR or RTS lines of the USB UART. The reset circuitry on the PIC 328P
