We design this board in order to have a tool when we need to program devices via JTAG, such as FPGAs, microcontrollers, etc.
With this design we have a USB 2.0 JTAG interface implemented with the chip manufacturer FTDI FT2232HL. Also this board has a RS-232 serial communication interface and 3.3V levels available, which gives us a number of possible applications.
- IC FT2232HL
- Mini-USB connector
- IC EEPROM series 93C46B/SN
- Voltage regulator
- USB connection LED indicator
- Power LED device programming
By J2 we access the JTAG interface signals and the serial channel.
We also have available +5V from the USB connector on the PC.
The LED D2 turns on, when properly connected the USB-JTAG board to program the device.
When the board is connected to the PC should turn the LED D1.
Connection to the PC is via the Mini-USB connector.
