[Solicitation Order] ESP8266 Open Source Game Console

Beggar’s version of ARDUBOY costs less than an Atmega32U4. I have been working on the Arduboy game console recently, but the price is relatively expensive and the information is relatively sparse. Occasionally I see an Arduboy with esp8266 but it is relatively simple, just like to supplement the complete version 2021/12/3 First edition It's almost done. Although there are some minor problems with the software, I can play some basic games. 2021/12/11 The second version of welding is completed. Since the ch340 was previously powered by LDO step-down to 3.3V, the WIFI of the ESP8266 When transmitting, the 3.3V will be instantly lowered to about 2.5V, causing the CH340 to reset. You can imagine that the task manager has been refreshing the device. This revision changes the ch340 to 5V power supply. Of course, instantaneous sudden changes in voltage cannot be ignored. ΠRC filtering and large capacitor adjustment are used to significantly improve the low voltage. Problem solved!
