![]() ![]() ![]() Note: A 3.3V device should only be programmed using 3.3V expansion board, otherwise a permanent damage may occur.ģ.3V device are: PIC12F1xxx, 16F1xxx, 18FxxJxx, 18FxxKxx, 24Fxxxx, 24Hxxx, dsPIC33xxx. (A clear circuit diagram is provided in the attachment.) In 3.3V expansion (LVICP) board a 5V to 3.3V,a voltage regulator such as LM1117 or similar is need.įig 5 and Fig 6 shows the expansion boards and circuit diagram for different series of microcontrollers. For different series of microcontrollers, different expansion board is used. ![]() I made the expansion board using perf board. It gives the advantage of easy to program the microcontroller to the user.Įxpansion board can be easily made using the perf board or in breadboard, because it is very simple circuit. The different series of microcontroller is having different pin and configuration for programming. Expansion board interfaces the programmer with the microcontroller. ![]()
