multifunctional pcb ruler

LEDs: flat, the pcb has no holes for the leds. Resistances: possibly 220 ohms, flat, there are no holes for resistances. From above: pin 1 RXD0, pin 2 TXD0. The LEDs are connected, starting from the left to: AD0, AD1, AD2, AD3, AD4, AD5, AD6, AD7, A8, A9, A10, A11. In the PCB there are holes at every centimeter, so that it can also be used to make circles. Its marketing is prohibited.
