My version of arduino with ARK connectors and better voltage regulators.
Fully working board
This version of board allow you to upload your code via usb uning CH330N microchip
Now there is also 3.3V high current voltage regulator as well as 5V
# ATmega328P piano synthesizer. (RUS: Синтезатор пиано на ATmega328P) #
***There are 3 versions of the Board: (RUS: Всего имеется 3 версии платы:)***
1. Lite (Does not have a Mini Jack connector and tone adjustment) (RUS: Не имеет Mini Jack разъема и регулировки тона)
2. Main (It has only tone adjustment buttons) (RUS: Имеет только кнопки регулировки тона)

A Lipo charger and protection circuit, a boost converter, a bunch of WS2812b and an ATMega328p - All of this makes a circuit forremote operating LEDS.
The circuit include a header to plug a RF module (nRF24 ?).
The ATMega is used with it's own internal oscillator (not precise 8MHz), but it's sufficient enough to drive this small circuit.
More compact speedometer with OLED display and temperature measurement.
This is the version 2 of the ATtiny85 speedometer. It features an ATmega328p uC that has more memory, pin functionalities, higher frequency and to which you can easily find the needed libraries (the ATmega328p is used on Arduino Uno). A serial-to-USB converter is needed for programming. It has the previous version's batte...
