### DESCRIPTION

USB Pic dev. board with CH340 and PIC12fxxx (PIC12f675).


You can learn serial comunication, create battery charger(1.2V NiMh,NiCD...), test RGB LED WS2128, IR protocols(NEC,RC5)

Scheme: https://ibb.co/hkOXkx




### TECHNICAL DETAILS / COMPONENTS

USB Power supply.

You can use this board how : USB<->UART convertor.

Without a processor you can control ch340 outputs, inputs(CTS-DSR-DCD-DTR-RTS,RX,TX)

You can use my Linux application to communicate with UART:

With a processor you can make IR receiver,battery charger(You have to calculate the values of the components according to your own requirements.)


### LEARN / TOPIC / BUILD INSTRUCTIONS

Now I soldering 2 pcb and i find 1 fail: i use fritzing for my project and problem is bad usb gnd-vbus polarity. If you want to use the usb A male conector you need solder it on bottom side :(

USB A female solder on top side.


I tested sw uart tx 9600 baud with internal oscilator 16MHz.

Now i tested IR NEC kodec scaner.
