[Verified] Arduino O development board

Overview

The circuit expands OLED and four buttons based on Arduino nano to facilitate the development of display menu interaction, leads to all IO ports, and uses USB TYPE-C (convenient). Normally, USB power supply is sufficient. If external power supply is required, the theoretical power supply is within 6-15V, and 12V is recommended.

There is not much else. The hardware is similar to UNO. Since it uses a 32-pin IC, it has two more interfaces, A6 and A7, than UNO. Please note that these two interfaces can only be used for ADC.

This project was originally created to make it more convenient for personal use. It has been boarded and verified for normal use. On the one hand, open source welcomes anyone who can use it. In addition, I also hope that you can give me suggestions on circuit design and PCB design. Let’s learn together

STM32 uses TIM1 trigger, why not configure TIM1?
It's still the same old question. The ADC of STM32F429 is very confusing when reading the example program. The ADC is configured as ADC_ExternalTrigConv_T1_CC1. This should be triggered by TIM1. Why i
