The software was developed using the ESP-IDF framework and freeRTOS as an RTOS.

I was also impressed with the ability to get a stable connection speed at 60 MHz when using simple SPI (i.e. The speaker can be seen in the first photo of the PCB.ДЇinally, I must say it again вЂ“ the screen is amazing in terms of price and size. The sound quality leaves much to be desired, some sounds are lost, but overall the sound is quite decent. Speaking of speaker, itвЂ™s very difficult to find a cheap SMD speaker that has enough room on the board, so I found a sounder with a good frequency range that fits on a PCB. I think this is enough to avoid damaging the speaker.

This driver converts from I2S to ADC, it can be configured to work with mono / stereo signal and the gain is configurable. It also contains a boost converter that guarantees a stable 3.3V output this solution avoids lower screen brightness and unstable battery drain behavior. If you do not change the value of the resistor R2, it will damage the lithium polymer battery. This resistor sets the charging configuration for the TP4056 chip. If you want to use less capacitance, then it is important to replace the resistor R2 so that the value is correct. This allows a larger battery capacity to be used.

Therefore, in this version of the PCB, the connector is used only for charging the device and connecting to the serial console to view the debug log.ДЄs you can see in the second photo, I used a standard PH 2.0 connector to connect the battery. It looks like every manufacturer implements USB-C sound differently. I thought about adding headphone support via the USB-C connector, but I dropped that idea because I didnвЂ™t find enough information about the implementation standard. In addition, I believe that apart from games, the device can be a very useful tool in developing projects with ESP32, because it is possible to run Arduino sketches and / or binary files of ESP-IDF projects from an SD card as an application without removing the main firmware. Therefore, it became obvious that the device requires a full layout of the SNES gamepad with the prospect of further updates. Well, yes, so far it is only capable of running 8-bit games, but after doing a thorough search, I found out that the first ports of the SNES and SCRUMV emulator already exist for ESP32. On the other hand, you may be wondering why add an SNES gamepad layout (directional buttons, 4 action buttons, Start, Select, L and R) when the device can only emulate 8-bit games? The most important thing is that the texts in the game are readable, you only need a magnifying glass. And all this in the tiny cartridge size of the first GameBoy.
