Usb To Serial 9 Pin Wiring Diagram. The arduino software serial library is for carrying out a serial communication between the nano and the computer. 4 led indicators.
Upload via serial adapter like pyupdi with serialupdi nano running jtag2updi or any microchip updi programmer or compatible. Note that you also need a 10 kω potentiometer to set the contrast of the display and a 220 ω resistor to control the brightness of the backlight. Opencm904s schematic is based on 32bit cortex m3 core stm32f103cb microcontroller.
