Update: Arduino Demos on ESPlay Micro V2

This is the updated version of the ESPlay Micro, the project Hackaday page at https://hackaday.io/project/166707-esplay-micro.

ESPlay Micro is a Handheld game console based on ESP32, which is from Espressif with great functionality and really mature on the software development side. This project most inspired by Odroid Go and Pocketsprite, those devices are great and have well community support, but some of them had some issues that can be updated. Odroid Go had shared its SPI for both display and SD card, and they need patched esp-IDF version for it and SD card not work very well in SPI mode, Then Pocketsprite only has esp32 WROOM module without psram and also without SD card support so limited portability for saving collection of games.

So that is what this ESPlay micro updated. With SD card support added, customers can collect many more games. High-quality sound I2S DAC also added to make it possible a good Walkman.

Compares to the V1 version, the main updates for the V2 are:

• Acrylic Case added
• Upgrade button and caps, to make the pressing feels much better
• Lipo battery added in the package
• Upgraded Lipo Charger IC TP4054, for faster battery charging
• 2.54” I2C breakout

Features:

• Integrated WIFI and Bluetooth 4 BLE
• 2,4" ILI9341 TFT Panel
• More button (expanded via PCF8574 I2C GPIO)
• Micro SD slot connected to SDMMC Host in 1 Line Mode for saving GPIO pin
• Integrated I2S DAC via UDA1334A
• Integrated USB to Serial for programming and debugging using CH340C
• Built-in TP4054 Li-Po charger
• I2C port for expandable function
• 3.5mm Headphone jack
