USB IR Boy

Note

This is my page about USB-IR-BOY. My original works are PCBs and schematics in Eagle for USB-IR-BOY and PROMMER.

USB-IR-Boy Prommer

Part list

one 16pin PDIP case Maxim RS232
four 10kOhm resistors
one 10MOhm resistor
one 2.2kOhm resistor
one 6Mhz crystal
two 22pF condensators
four 100nF condensators
one fast diode (dont think it matters what type)
RS232 connector

Electronic schematic

Following electronic schematic represents the home made prommer that we have been using to program the MCU.

In the schematic, there is optional regulator sircuit to be used if you would like to use higher voltage than 5V as the source voltage of the board.

Created with gEda

Some points

Vcc is 5V
Vreg is 3.3V reguladed by MCU
MAX232 power pins are not shown in the schematic due the way gEda handles default chip power pins.
( VCC=pin 16, Gnd=pin 15)
