How to use
It is very easy just to tie this board to the PC with a USB cable. It is not necessary to change the setting of the board. The power supply of the module supplies by default 3.3V from 3V3OUT of FT232RQ.
MEMO
-
Current measurment To measure the current, please cut the shorting 1pin and 2 pin of CN6. And connect an ampere-meter between the pins of connector CN6 to monitor the current directly.
-
About the power supply of the module
When you use external power supply, please supply power from 15 and 16pin of CN3. On this configuration, please cut the short circuit 1pin and 2pin of CN5 in order to separate 3V3OUT of FT232RQ. -
USB to serial UART interface
It needs to install driver of FT232RQ to use USB for UART interface. The drivers are available on FTDI website. http://www.ftdichip.com/Drivers/D2XX.htm In addition, by the application development, please assign GPIO as follows.
GPIO | UART |
